First, artificial control:
1. The dry base is painted with white and grass to prevent the pests from laying eggs. In the period of spawning of dried cockroaches such as Pleurotus ostreatus, the main coating is white coating agent (the preparation ratio is 5 kg of lime, 0.5 kg of sulphur powder, 20 kg of water, 0.02 kg of rosin); the grass is tied on the dry basis, The larvae are lysed at the beginning of the egg, and the grass is burned intensively.
2, artificially cut off the worm's tip: the main spotted pests such as the two-spotted black velvet beetle are invaded from the top of the young shoots. After the picking of the pepper, the shoots at the top of the young shoots should be cut 5-10 cm below the dead part. Burn it out in the middle.
3. Thoroughly clean the litter and reduce the source of pathogen infection.
4. After the leaves of the peppers are defoliated, use the grass to wipe off the overwintering adults on the branches. Eggs.
Second, the drug control:
1. Spray protection blade: After the pepper is harvested, it is the prosperous period of its leaf disease, 70% methyl thiophanate 600-800 times liquid in this period, or 25% powder rusting wet powder 800 times liquid. It can effectively control the spread of pepper disease and brown spot disease.
2, dormant sulphur sulphur mixture: spray the stone sulphur mixture before germination after the defoliation of the pepper, can effectively kill the pathogens over the winter on the tree.
