What are the prevention and control methods of the three insects in early autumn?

We all know that autumn is the harvest season, but it is also the season of high incidence of pests and diseases, and in the early autumn season, the insect infestation is particularly serious, and if the management cannot keep up, it is very likely that our economy will suffer lossesTherefore, in terms of prevention and control measures, agricultural prevention and control should also be the mainstay, supplemented by physical and pharmaceutical prevention and control methods, only in this way can we better increase productionI hope everyone can know this, and at the same time, we must strictly follow the instructions for the use of the dosage, so that our lives will not be affected.

1. Which three insects are specifically referred to in early autumn.

Generally speaking, the three insects in early autumn refer to the bean pod borer, deciduous flies and red spiders, for red spiders, we can be said to know very well, the red spiders on the beans, also known as bean leaf mites, can be sprayed with a sprayer to hit the encirclement after the occurrence of pesticide spray, which can prevent the spread of red spiders. Pod borers and deciduous flies can prevent the spread of pests and diseases by removing fallen flowers and feet in the field and plucking infested curls and carobs, hopefully everyone will be aware of this.

2. What should be paid attention to in the use of pesticides?

Many pests and diseases can be solved with pesticides, for the choice of pesticides, it is generally necessary to go to the regular seed station to buy the corresponding drugs, I hope everyone can know this, but we need to pay attention to the use of the content of the agent must be strictly in accordance with the instructions, only in this way will not affect our personal life.

3. What other things do we need to pay attention to?

There are a lot of insects in the land, therefore, we must observe the growth of crops in time, if there is a problem, we must solve it in time, only in this way can we strangle the danger in the cradle, and we need to pay attention to the fact that we must plant the corresponding crops on the right land in life, and we must not use the land to do experiments.

In early autumn, the three insects are harmful, and the control methods are as follows: remove the fallen flowers and corners in the field, and remove the damaged curly leaves to reduce the source of insects; Set up black lights, use the phototactic habits of adults, and trap them; spraying for culling; Use sticky insect plates to trap and kill adult insects; Adults mainly lay eggs on the back of the leaves, and the spraying solution focuses on the back of the leaves. It is necessary to pay attention to the rotation of drugs and advocate the use of high-efficiency and low-toxicity biological pesticides.

It can be controlled by drugs, it can also be controlled by crops, it can also be controlled by some vegetables, it can also be controlled by some pesticides, and it can also be controlled by spraying pesticides.

To spray pesticides in time, we must choose targeted pesticides, we should also pay attention to the time when spraying, we should choose excellent varieties for planting, we must also water in time, and we must apply organic fertilizer in time.

Insect pests occur seriously in early autumn, and the three insects in early autumn are pod borer, leaf miner fly, and red spider. In terms of prevention and control, agricultural prevention and control is the mainstay, and both physical and pharmaceutical prevention and control are emphasized.

The control methods for pod borer are:1Remove fallen flowers and corners in the field, and remove the infested curly leaves and beans to reduce the source of insects.

2.Set up black lights, use the phototactic habits of adults, and trap them; 3.

The agent is 5% fipronil 2000 times solution or 40% fenvalerate 6000 times solution, deltamethrin 3000 times solution and other agents, and sprayed once every 10 days.

The control methods for leafminer flies are:1Use sticky insect plates to trap and kill adult insects; 2.At the beginning of larval infestation, choose an insecticide with both systemic and contact killing effects, such as 48% chlorpyrifos emulsifiable concentrate 800 1000 times, etc., and spray 2 times 3 times in a row.

The control methods for spider mites are:1Timely removal of insect leaves and burning, timely irrigation and fertilization in case of dry weather, promote plant growth, and inhibit the proliferation of leaf mites.

2.General treatment with a selective acaricide is carried out before the pod-setting period and after the pods are harvested, focusing on spraying evenly on the underside of the leaves. It can be sprayed with 20% compound liuyangmycin EC 1000 times or avermectin EC 1500 2000 times, 15% pyridafen EC 3000 times, 20% metamidine EC 2000 times, etc.
