Get twice the result with half the effort in winter

Pests do not eat or move in winter, which is the weakest link in their life cycle. Therefore, pest control in winter can often get twice the result with half the effort. The main measures are as follows:

Some pests often lurk in the residues of host plants, such as stubble, residual plants, withered branches, fallen leaves, fallen fruits and so on. After harvest, these residues are collected and burned, compost or buried deeply, which can destroy a large number of overwintering pests.

Winter ploughing and winter irrigation through deep ploughing in winter can change the original living environment of pests, make the pests in the deep soil turn to the surface and dry to death, freeze to death or be pecked by natural enemies, so that the pests buried deep in the ground can not be normally feathered and suffocated, thus reducing the source of overwintering insects; followed by winter irrigation after tillage, it can not only settle and weathered the soil, but also freeze to death some overwintering pests.

After crop harvest, some pests are often transferred to the field and surrounding weeds to survive the winter, and in early spring, these weeds often become the "sanctuary" and wild host of overwintering pests. Therefore, combined with fertilizer production and eliminating weeds inside and outside the field, it is an effective measure to control overwintering pests.

Some pests (corn borer, etc.) of the treated host often overwinter in the stalk or ear axis of the host crop after harvest. The treatment of stalks or spikes of these host crops in winter can greatly reduce the overwintering base of pests.
