60 spring classic pesticide formulations, let you 1 minute understand!（2）

Many farmers leave a message that for some crop diseases and insect pests, the effect of a single drug is not very obvious, in fact, if the existing pesticides are mixed reasonably, can play a good effect to improve the prevention effect, reduce the dosage, reduce labor costs.

Biological control will be the main direction, reducing drug use, green health is the fundamental development of agriculture.

Another pesticide factory accident!Much of the implementation of the suspension of production to be examined, agricultural chemical raw material prices to come?

One person has been killed and four others injured in a burst fire at zhaoyuan jinheng chemical co LTD in xinzhuang town, yantai city, shandong province.

According to the preliminary investigation and analysis, the direct cause of the accident is: leakage of water in the jacket of the tetraphenyltin reaction kettle or excessive water content of the raw material stannic chloride and the solvent xylene, violent reaction to meet the incomplete reaction of the metal sodium to produce hydrogen, and the air to form an explosive mixture of gases, when static electricity and other ignition sources occur.

Through the state industrial and commercial information website query, the explosion of the main production of tin chloride triphenyl (also known as tin acetate triphenyl), tin acetate triphenyl, tin hydroxide triphenyl;

Tin triphenylacetate is commonly known as daoqu jing, which is mainly used to prevent rice blast disease, daoqu disease, striped spot disease, sugar beet brown spot disease, potato late blight, and has a special control effect on snails, algae and water snails, which is better than a kind of medicine bailuoban.

After the March 21 incident, most domestic chemical enterprises took the initiative to carry out hidden dangers investigation, but some enterprises still had hidden safety problems.

Many provinces emergency deployment clear investigation time

On March 22, the emergency management department held a symposium on the safety work of chemical industry (hazardous chemicals) along the Yangtze river in wuhan, hubei province, attended by provincial emergency management departments in hubei, Shanghai, anhui, jiangxi, hunan, chongqing, sichuan and yunnan.At the meeting, it was proposed to strengthen the screening, rectification and risk prevention and control of potential safety hazards, pay close attention to the implementation of the main responsibility of enterprises for production safety, seriously pursue accountability, and accelerate the construction of emergency facilities.

At the same time, jiangsu, hebei, liaoning, anhui, hainan, shandong, sichuan, guizhou, fujian and other provinces, emergency deployment of hazardous chemicals production safety hidden trouble investigation and rectification work.According to incomplete statistics, up to now, more than 20 provinces in China have carried out the work of hazardous chemicals safety rectification.

At the same time, the local chemical safety regulation work set a time requirement.

A week-long inspection of hazardous chemicals was launched in Beijing on March 24.

Shandong requires all enterprises of hazardous chemicals and explosion-related dust in the province to complete self-examination and self-correction of safety risks within 3 days, and all emergency management departments of cities and counties should complete the inspection of relevant enterprises within a week.

At the end of march, hubei province supervised and urged enterprises to complete the investigation and input of safety risks of hazardous chemicals with high quality.

Jilin, henan and other provinces are required to complete the inspection and input of dangerous enterprises before the end of June 2019.

Gansu province from today to the end of July the whole province to carry out a special safety rectification of chemical enterprises.

Tianjin city from March 23, the establishment of the inspection team to launch a 20-day blanket thorough investigation of chemical risk sources.

Carpeting the whole process of chemical production

     

In addition, the state council's safety commission also called for in-depth investigation and rectification of safety risks in coal mines, non-coal mines, road traffic, fire control, construction and other industries to prevent all kinds of accidents.

Emergency notice issued by jiangsu province, focusing on the investigation of safety risks in the production, storage and operation of hazardous chemicals;

Qinghai province committee office issued an urgent notice, requiring the deepening of road traffic, dangerous chemicals, mining, fire protection, building construction and other special campaigns, immediately organization of chemical enterprises in qinghai province and joints between urban and rural areas, rural, remote courtyard, old workshop and other places to "carpet, trawl, full coverage" hidden perils.

Jiangsu province issued an emergency notice on March 22, requiring secret investigations, joint law enforcement and centralized law enforcement to maintain high pressure on areas and units with major risks and hidden dangers, key parts and links, and accident prone areas and units.

Beijing requires, increase law enforcement frequency, maintain high pressure situation, strict inspection of habitual violations, strict inspection of the operating procedures do not implement the behavior, strict inspection of hidden dangers, investigation and treatment of formalism, will be reported to the municipal emergency management bureau every day.

However, this round of production stoppage is not finished, then another explosion, through the state industrial and commercial information website query, the explosion of the main production of tin triphenylchloride (also known as tin triphenylacetate), tin triphenylacetate, tin triphenylhydroxide;

Raw material prices may rise again

No matter be chemical industry of water of sound water chemical industry 16 chemical companies are forced stop work, or countrywide each district rectify check, a large number of chemical plants stop production or delay production, had caused the concussion of whole chemical industry market apparently.The price of chemical products is in chaos, which directly leads to a surge of price increase due to the shortage of goods.

It is understood that the herbicide market, glyphosate glycine manufacturers quote to 25,000 yuan/ton or less;The downstream terminal of glyphosate was gradually started, and the quotation was within 147,000 yuan/ton.At the same time, the supply of many selective herbicides is relatively tight, such as cyperazine, oxaoxone, spermaquinolone, nicosulfuron and pentafluorooxalamine.

In terms of pesticides, abamectin manufacturers have a strong willingness to raise prices, and nicotinoids are mainly stable. Malathion, propylbromophosphorus, diazarin, acarate and biphenylhydrazine are limited by the limitation of starting production and high prices.

As for fungicides, due to the pressure of environmental protection, the enterprise started less and the supply was relatively tight.Pyrazole ester manufacturers fierce competition, the downstream inventory gradually digestion, market wait-and-see mood is serious, the market price reported 190,000 yuan/ton.

Will tell to each district dealer, the biggest worry is whether stock up on goods, but what need to remind is, dealer can buy goods according to local condition, before rising in price tide, polish eye, want reason to deal with, can ask cooperative manufacturer specific circumstance directly, avoid to fall into the trap that certain manufacturer takes this to hype a price!

Both explosions belong to a big classification industry, which shows the importance of safe production. It is estimated that the situation of safe production will be more severe in the future, and it is called on enterprises to pay attention to safe production to avoid the occurrence of tragedy.The price of pesticides may not be very optimistic for distributors and growers. I hope you can pay more attention to your upstream enterprises and make preparations in advance.

Key Points and Remedial Measures of Apple Flowering Frost Defense Technology

Irrigation of water once before and after germination to reduce the soil temperature and delay the phenological period. Due to the high water content of the soil, the temperature on the ground drops slowly, which can supplement the water of the trees, and can reduce the ground radiation, increase the air temperature, and delay flowering.

     According to the weather forecast combined with the weather, smoke was smoked in the evening before the frost. If the temperature is below -5 ° C, the effect is poor. There are two kinds of smokers: one is anti-frost aerosol, the effect is very good, the formula is 20%~30% ammonium nitrate, 50%~60% of sawdust, 10% of waste diesel, 10% of fine coal powder, these materials The finer the better, and then put into paper bags or containers for standby; the other is commonly used smoking materials, which are formulated as crop tobacco, weeds, fallen leaves and other materials that are easy to produce. To make a cigarette stack method: first set up a wooden stake in the middle, and then put a wooden stake in the "ten" character, then put the smoking material together and put it around the stake, and finally put a thin layer on the stack. earth. The smoke stack is generally 1.0~1.2m high, and the bottom diameter is 1.5m. It can be placed in 3--4 heaps per acre. When you smoke, first remove the two stakes, and then ignite them with flammable materials in the holes near the ground. Ignite immediately when the temperature drops to -0 °C. If the smoke pile burns too much, you can press some soil to promote it. Warming and defrosting to alleviate frost damage.

Spraying Shanghai Yongtong Kuabao Organic Water Soluble Fertilizer on apple leaf surface to enhance the cold resistance and stress resistance of the tree, alleviate the damage caused by low temperature freezing damage to the tree body and increase the fruit setting rate. At the flowering stage, a total of 3% of polymycins 1000-1500 times +0.3% borax + 0.1% glucose is sprayed in the whole garden, and 5% isoform urea suspension can be used 1000-1500 times to prevent mildew and increase the fruit setting rate.

How should tomato colouring not even do?

Tomato in the transition period management negligence, directly affect the tomato color.

So, what factors can cause tomatoes to turn uneven color?

01. The temperature is too high or too low

The color of tomatoes depends on the lycopene in the fruit.Practice has proved that lycopene is easy to form when the temperature is 23-28℃, which promotes the fruit to turn color.If the temperature drops below 13℃ or above 32℃, lycopene production is blocked.

02, the use of fertilizer is not reasonable

When nitrogen, phosphorous, potassium scale is maladjusted, especially when turn color period nitrogen high potassium is low will affect the formation of solanthin, lead to turn color is not uniform, the tendon that often appears on tomato rot fruit, green skin fruit, tawberry fruit and so on is caused by unreasonable fertilizer.Potassium fertilizer can promote fruit expansion and improve fruit color. Therefore, there is a large amount of potassium fertilizer applied in the fruiting stage, and it takes a process for potassium fertilizer to be absorbed and utilized by vegetables after it is applied into the soil. Therefore, potassium fertilizer should be used before fruit expansion, and water soluble fertilizer with high potassium once every half a month can promote fruit expansion and color transformation.Application of potash fertilizer before the fruit turned red was ineffective.At the same time adhere to the foliar spray containing calcium, magnesium foliar fertilizer, so that the color even.

03, too many thin leaves

Sparse leaves should be paid attention to, be sure to retain the right amount of leaves.In the stage of transchromatization, the diseased leaves and the old leaves at the bottom of the plant, the yellow leaves and the leaves around the fruit that block the light should be removed. Other leaves should not be removed as far as possible.The roots are raised on leaves, with too few leaves and too few photosynthetic accumulated nutrients. In this case, the root system is prone to premature aging, and its ability to absorb nutrients is greatly weakened, thus affecting the yield and quality of fruits.For the last batch of tomatoes in the transchromative stage, it is necessary to keep at least 4-6 leaves. It is not correct for some vegetable farmers to leave only a few parietal leaves.

04, fruit disease prevention should be timely

For example, tendon rot, stripe virus disease can lead to poor staining of tomatoes.These two diseases have a lot to do with proper management and should be combined with management measures for comprehensive immunization.In order to promote tomato color, many vegetable farmers excessively increase the temperature of the shed.It's not very scientific.High temperature will inhibit the production of lycopene, affecting the normal coloring of tomatoes. 

Tomato hualian fruit can be divided into the following several cases: chapped fruit, tawny fruit, tendon rot fruit, cork fruit, virus fruit, canker fruit and so on.Different situations have different causes and different preventive measures.

Chapped fruit: the fruit enters the ripening stage and appears at the shoulder or navel

The projective chaps are called chaps.The most important reason for chapped skin is improper control of temperature and humidity, and the secondary reason is improper leaf picking.For example, in the period of green fruit or white ripeness, high temperature and drought in the shed, low humidity, leading to dry peel will appear crack;The dew on the peel surface was quickly evaporated by sudden wind, and then tiny chaps were formed on the peel surface.

The prevention of tawny fruit should be started from the following two aspects. Firstly, balanced fertilization is recommended. During the leavening period of tomato, it is recommended to apply the full-water-soluble fertilizer with high absorption and utilization rate (acacia 20-20-20+TE or acacia 15-6-35+TE).Secondly, reasonable temperature control. In the management process of the shed, it is recommended to air out when the shed temperature exceeds 25℃, and try to keep the shed temperature below 28℃.

Tendon rotten fruit: tomatoes into the mature stage, in the fruit shoulder always appear a piece of green spots, with a knife cut open the peel, can find the skin vascular bundles brown, we call it tendon rotten fruit.In the case of excessive nitrogen fertilizer, insufficient potash fertilizer and excessive watering, tendon rot fruit is easy to occur.

The key to prevent sinew rot is proper watering, balanced fertilization, avoid soil moisture too much, high nitrogen and low potassium.It is impossible to make the fruit become normal in the plant which has been damaged by the sinew. It is recommended to spray the young fruit with potassium dihydrogen phosphate (nutritaphosphorus potassium) in time, and at the same time flush with high potassium (aike 15-6-35+TE) water-soluble fertilizer. After watering, pay attention to timely weeded to maintain good permeability of the soil.

Corknut: when the plant is short of boron, the fruit surface is prone to corknut brown streakings, which do not expand or rot, and the fruit is hardened. It often happens near the fruit pedicle.Prevention is simple: apply boron containing amino acid foliar fertilizer (root bovine amino acid water soluble fertilizer) regularly before and after flowering.

Virus fruit: tomato fruit surface appeared semicircular ring markings, leading to the fruit face, and the situation in the shed sporadic occurrence, can be judged as a virus disease.In recent years, hualian fruits caused by viral diseases have occurred from time to time, which is related to the resistance of varieties.

In order to prevent the appearance of virus diseases, it is suggested to spray the related insecticides of virus diseases on a regular basis, at the same time, cooperate with thiamethoxam, imidacloprid and other insecticides to eliminate the virus-spreading pests.

Canker fruit: tomato canker disease can form white near circular disease spot on the fruit surface, the center of the disease spot has brown small point, looks like a bird's eye, this is a typical disease of canker disease.
