Comprehensive control of diseases and pests in winter mulberry fields

The pest control in winter in mulberry gardens is generally neglected by the silkworm farmers. There are many factors such as low enthusiasm for pest prevention and control in mulberry fields, low intensity of control and prevention and control, and so on, which results in the increasing number of winter worms in mulberry gardens. In fact, a solid improvement of winter pest control in mulberry fields will greatly reduce the population density and index of overwintering populations and effectively control the occurrence of pests and diseases in mulberry fields in the following year. Specific prevention and control measures are as follows.
1. Chemical control: The use of pesticides in the winter to control mulberry pests is not afraid of damaging silkworms, but also improves efficacy and ease of operation. After the late autumn silkworm rearing, it is necessary to uniformly spray a high-efficiency pesticide on the mulberry garden, and the enemy can kill 2000 to 3000 times plus omethoate (or 80% dichlorvos) 1000 times: or 20% to resume 2,000 times. With a misting machine, Mulberry Garden and its surrounding crops and trees were sprayed with insecticides.
2. Clean Mulberry Garden: Collect the mulberry field and surrounding leaves and weeds before the winter turning, and burn them together or compost them. This can effectively reduce overwintering pests such as mulberry horses, red spiders and mulberry brown spot diseases. The mulberry field of mulberry tree dwarf disease should be inspected one by one, and the diseased plants were found to have been completely excavated and burned.
3. Sedula seduce: After mulberry defoliation till winter twigs, branching, seduce mulberry sedge, mulberry caterpillar and other pests sneak into the sow in the winter. In the spring before the pests are inactive, they are concentrated and burned, killing the pests in the sows.
4. Winter turning: The soil is deep-frozen before it is frozen. The depth is about 20cm. It can turn overwintering pests such as mulberry eggs, mulberry catfish larvae, mulberry mosquito capsules, chafer larvae and some adult worms to the surface. It is frozen to death, sunburned or eaten by birds.
5. Pruning and shearing: Because dry piles and branches are wintering sites for diseases and insect pests, the eggs of mulberry silkworms are overwintering at the shoot tip. The mulberry ululae egg overwinters on the branches, and the mulberry worms overwinter in dry mulberry branches and piles, so pruning and cutting are very important. The dry piles, death fists, and pests and diseases that have been refurbished should be brought out: Mulberry Park is concentrated and burned to prevent the spread of pests and diseases.
6. Artificially obliterate, fill in the hole: use burlap or grass to kill the scale insect and mulberry (to kill the mulberry to be intensively in the trunk after hatching in February, mulberry), and then use 10 times the oil emulsion to kill the residue body. Use bamboo strips to scrape the mulberry and wild egg masses on the trunk. The mulberry cracks and boring holes are filled with lime or clay to make the latent overwintering pests unable to climb out; the mulberry beak can be used to cut the stalks, and 80% of the dichlorvos can be used to smash the tips. The mulberries are placed on the mulberry trees. In the defecation hole, if you see the new hole, the defecation should be blocked in time.
