Removing a pest or an egg in the winter is equivalent to destroying hundreds of pests in the spring and summer of the second year. Pests have fewer workers and fewer investments in autumn and winter. The method is simple and effective.

To understand and master the hibernation patterns of pests, corn borers live in the stalks, cobs and roots of corn, millet, sorghum and other plants; wheat fly larvae thrive in wild grasses; wheat stalks are old and larvae. Hidden in the soil for winter; larvae winter as larvae; sweet potato hawk moth larvae in the soil for winter; cabbage caterpillars spend their winters in the hidden leaves, weeds, bark and other hidden places near the vegetable garden; potato ladybugs cluster with adults The lee, the cracks in the sun, the winter under the stones, and the weeds; the adults spend winters in the soil, under the fallen leaves, and in the weeds; the beet weevil spends winters with adults and larvae in the soil; the spider mites are mostly adults or eggs. The leeward, sunny branches, cracks, and axillary buds have been cracked for the winter.

At the turn of autumn and winter, pests such as rice, corn, millet, sorghum and other crop residues and pests in the straw should be used as a means of "destroying the house" by destroying the roots and removing stubble, deepening the frozen mat, returning the straw to the field, and removing the litter and weeds in the field. Come to a big turn to expose the pests to the surface of the earth. This will make it easier for birds to feed or freeze. Conditional farmers can be controlled by spraying or burning.

Treating soil with pesticide granules such as phoxim can eliminate a large number of underground pests such as cockroaches, cockroaches, wireworms, and floorworms.

In the autumn and winter, we actively build farmyard fertilizers, eradicate weeds, collect debris and branches, and eliminate eggs. In particular, serious land masses occur in various borers. In autumn and winter, all kinds of debris must be removed and destroyed.

For fruit trees and farmland protection forests, it is best to use “whitening agent” to coat the trunks, clean up the litter between the fruit trees and clean up the trunk holes to clear the pest eggs in between.
