How to avoid using expired pesticides?

Each pesticide has a certain shelf life, which can be used in the guarantee period to ensure the safety and effectiveness.Crops once used the expiry date of pesticides, rather than treating extermination effect, instead will cause the disease and insect resistance, delay optimal period, the prevention and control of plant diseases and insect pests to difficult or unable to control, more major is to make the crops to produce the adr, irreparable consequences.Therefore, farmers' friends must ban the use of expired pesticides.So how do you avoid using expired pesticides?

When choosing pesticide, see production date.

The choice of pesticide must go to the formal agricultural capital unit.When the choose and buy, the first to see need to purchase pesticide varieties, and then to see the pesticide production date and product manuals, because pesticides have shelf life, such as found that more than shelf life of pesticides, don't buy, close to the shelf life of pesticides, try to do with how many, how much to buy now buy now.

The remaining pesticides in the home have expired or have no conclusive evidence that effective pesticides are not used.

Rural households if entities from the residual pesticide, in this year before use, first to see the label are in good condition, whether still in the warranty period, if found over shelf life of pesticides, advise or best without.The remaining pesticides, such as the label shedding, cannot be used to identify the pesticide varieties, so as to avoid the harmful effects on the crops, resulting in greater economic losses.

The residual pesticides are labeled.

The remaining pesticide stored by the farmer must have a complete bottle sticker, the name of the pesticide, the batch number, the production date and the expiration date should be clear.If the bottle is damaged, the farmers must write the shelf life of the pesticide and use the cautions, and put it on the outer packing of the pesticide.

The remaining pesticides are in good storage.

The remaining pesticides are improperly stored, which can reduce the insecticidal effect and even produce the drug damage.Therefore, the pesticide that the farmer bought in that year has not been used up, ready to use next year, in the custody process to do the following:

1. Seal preservation: some pesticides are volatile and ineffective, causing air pollution. The bottle cap must be tightened and sealed when storing.

2. Keep the temperature: most powder pesticides are susceptible to the high temperature.The higher the temperature, the easier it is to melt, decompose, volatilize, and even explode.Some emulsion pesticides will also destroy their emulsifying properties and reduce the effectiveness after they encounter high temperature.And some bottles of liquid pesticide when faced with after low temperature freezing, form a block, or make the bottle burst, should keep indoor temperature when keeping this kind of pesticide in more than 1 ℃.

3. Avoid light: some pesticides are afraid of light, long-term exposure to light, can cause the decomposition and deterioration of pesticides, and avoid high temperature and sun exposure during storage.

4. Keep dry: powder pesticide and plant conditioner, it is easy to absorb moisture.Therefore, the storage of pesticides should be kept dry, and the rain will fall.Keep the Windows open for ventilation and keep the humidity below 75%.

5. Avoid mixing: pesticides are classified as alkaline, acidic and neutral.The basic pesticide has the enemy, the sulfur mixture, the bordeaux mixture, etc.Acid pesticide has deltamethrin and so on;The neutral pesticide has a gram distemper and so on.These three different kinds of pesticide, should be kept in storage in storage, the distance is maintained at more than 0.5 meters, otherwise, will make the pesticide deterioration failure.

6. Rigorous mixing: for two pesticides that were not used in that year, they should not be mixed in one bottle to avoid failure.
