How to prevent and control the weight of wheat sucking insects? These methods are quickly collected!
As one of the most important crops in China, wheat is essential in life. In the north, you can see large areas of wheat fields. During the planting process, the most important thing is to control the pests, such as the larvae. So how do you control the wheat sucking insects? Let's take a look at it.
First, wheat sucking insects
Wheat midge is a common pest of wheat. During its larvae, it sucks the grain juice that is being grouted, hence the name of the larvae. The larvae are wintering in the soil and phlegm in the booting stage. When the head is stalked, the worms are feathered, and the eggs are produced in the wheat ears. After the larvae hatch, the larvae are harmed by the flowers and the granules are sucked. Before the wheat is harvested, the larvae enter the soil for winter.
Second, what harm does the larvae have on wheat?
Wheat heading and flowering period is very vulnerable to wheat sucking insects. Once the wheat is harmed, if it is not timely prevented, it will cause 10%-30% reduction of production, and serious damage may be directly caused, and the damage is very serious.
Third, the control method of wheat sucking insects
Agricultural control (mainly prevention)
(1) In the case of wheat planting, insect-resistant varieties can be selected, and different varieties of wheat have different pest resistance. The basis for the purchase can refer to the incidence of wheat midge in the previous years. If the pest is serious, then it is necessary to purchase seeds with strong insect resistance.
(2) When wheat is planted, we can use the rotation method to prevent pests. If a piece of land is used for growing wheat for several years, the probability and harm of the occurrence of the larvae is increasing, but if it is carried out, Planting other crops, such as beans and cotton, can also prevent it every other year.
Chemical control
Chemical control is also divided into two methods, one is soil treatment, and the other is chemical control.
(1) Soil treatment: Before the wheat is planted, the soil should be deeply ploughed, and then the mixed toxic soil will be evenly scattered in the ground, so that in the deep ploughing, the toxic soil can be turned to the bottom, so that it can be started. For the purpose of prevention and control, toxic soil can be made with phoxim or methyl isoflavin.
(2) Pharmacy spray: During the heading period to the flowering stage of wheat, it is found that there is a larvae in the wheat field, then it should be immediately sprayed with a chemical spray. There are many kinds of medicinal agents that can be selected. Common chlorpyrifos, kungfu, deltamethrin Anything can be done, as long as they are not particularly difficult to control, they can be controlled.
The above is the introduction of wheat sucking worms. When planting wheat, it is best to do certain measures to control the larvae. This is also to avoid the troubles in the later period. If the early period is not done well, then the late stage can not be careless, in order to ensure wheat. The production of this pest must be done well.
