How to use insecticide for the best effect

No matter what kind of crops we grow, insecticidal work is very important. Insecticidal is a key measure to ensure the healthy growth of crops and not to be harmed by pests. When we are killing insects, pesticides and other pesticides are the main pesticides to kill insects. So how can we use pesticides to ensure the best results? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Habits of pests and timely use of drugs

There are many kinds of pests, some of which are mainly in the morning and some in the evening. Therefore, on this basis, our spraying time should be after 9-10:00 and 16:00. Because after 9 o'clock, the dew on the crops has gradually dried up, and this is when the activity of sunrise pests is at its peak. Therefore, if the medicine is used at this time, the pest can be directly exposed to the liquid and improve the efficiency of killing insects. After 16:00, the ultraviolet radiation in the sun decreases and the temperature gradually drops. And it is also the active period of nocturnal pests, at this time, medication can effectively control nocturnal pests.

2. Pest mouthparts and selective medication

There are many kinds of pests and there are different types of mouthparts. First of all, there are the pests of chewing mouthparts, which mainly eat the root buds on crops. On the other hand, the pests of piercing and sucking mouthparts mainly feed on the liquid in the crops. Therefore, if we want to improve the effectiveness of insecticide control, then we also need to choose drugs according to the mouthparts of pests. For example, contact insecticides, internal inhalers and so on, in the control of prick-sucking pests, an appropriate amount of penetrant can be added to pesticides to effectively improve their control effect.

3. Method of medication

The harmful parts of pests to crops are also different. For example, underground pests mainly harm the roots of crops and ground stems and so on. Therefore, when we control underground pests, we can spread pesticides on the ground, and then carry out deep ploughing to fully mix pesticides with soil. At the same time, it can also be applied near the root, or made as poison bait for crop control. For gnawing pests, then as well as stomach poison and contact insecticide-based spray control.

4. Other measures

When we use pesticides, we should be careful not to use a single pesticide for a long time. Otherwise, pests will become more resistant to pesticides, and the offspring produced by adults after mating will become more resistant to pesticides. Therefore, when we use drugs, we should rotate the drugs to prevent pests from developing drug resistance. Then it can be mixed according to the characteristics of pesticides, adding an appropriate amount of synergist, can improve the properties, enhance its insecticidal effect, but also prevent the emergence of drug resistance of pests. Finally, when we choose pesticides, it is best to give priority to biological pesticides with high efficiency, low toxicity and low residues.

The above is a brief introduction to how pesticides work best. That's all for today's introduction. This article is for reference only. I hope it can help you all.
