Silkworm is a white soil silkworm, generally active in seedlings or crops of the roots, stems and leaves and other parts, the harm is extremely great, for farmers, the control of real estate insect pests is a big problem, this pest is not to be removed, but to rely on the correct control methods.
The old evil shared the prevention and control methods with everyone, which was very practical and the effect was excellent.
<h1 class= "pgc-h-center-line" > methods for the control of silkworm infestations</h1>
The control methods of silkworm pests should be carried out from the aspects of field control, induced killing, drug seed mixing and physical elimination methods.
1. Field control
Field management is a major part of the elimination of silkworms, and the two most important points are rotation and preparation of soil for control.
(1) Land rotation: The purpose of rotation is to prevent silkworms from overwintering and hiding in the land, continuous cropping will continue the insect pests, and the soil should be deeply ploughed several times during crop rotation, turned to the ground, combined with artificial or pharmaceutical treatment methods to solve. The field should also be weeded in time, and the presence of weeds gives the silkworms a place to live, aggravating the insect infestation.
(2) Soil preparation: soil with drugs to prepare, strong pertinence, sprinkle fine soil on the surface of the soil mixed with drugs, after ploughing the land, silkworms will be infected with drugs and die, optional octyl thiophos granules, the effect is good.
2. Induce hunting
Induction of hunting should be based on the growth characteristics of silkworms.
Silkworms like to eat young leaves in their young age, the most rampant in the spring and autumn, the summer temperature is high and the harm is relatively small, and the nocturnal activity is frequent, according to these characteristics, you can find a suitable period to use the young leaves as bait, sprinkled with insecticides, and when they eat, they are invisibly eliminated. Of course, when inducing, you can also directly burn it with boiling water, and the silkworm will die.
3. Drug seed mixing
The most thorough harm of silkworms is to start with seeds, and even without time to grow, crops are nipped in the bud, mainly for young silkworms. The drug is fished together with the seed in a certain proportion and then re-sown, which also plays a role in controlling other insect pests. However, at the time of germination, some of the seeds will still be destroyed, and the seeds need to be replenished at a later stage.
There are many agents that can be used, including 50% parathion, 20% isosalphos, etc., the proportion of seeds is depending on the situation, and the concentration is larger in the areas where the pest infestation was more serious in the previous year.
4. Physical annihilation
There are many characteristics of silkworms, the most significant is the tendency to ferment the sweet and sour smell and black light, and the silkworms are directly used to gather them together in the most prosperous period of silkworm activity, and then artificially killed. Adding sugar to fermented bread or using a black light has a noticeable effect, which is how to physically eliminate it.

Want to kill silkworms efficiently, often in combination with a variety of methods to use together, such as after field control, the vegetable garden is still unable to avoid this pest, then you have to start using drugs to induce, or use physical control methods, the purpose is to introduce silkworms, so as to ensure high efficiency.
It should also be noted that it is best to choose the best control when the silkworm activities are at its peak, otherwise it is not complete at all.
< h1 class="pgc-h-center-line" > the last word</h1>
Silkworms must be eliminated, learning how to control it is very important, for farmers, just expect that field to eat, the degree of harm of this insect pest is very large, when the grain is not harvested, I hope that my sharing can help everyone.
