In recent days, the temperature has gradually increased, and pests such as mulberry scale insects and scale insects will infest a large number of mulberry sprouts. Diseases such as mulberry disease and mulberry plaster disease will also infect mulberry trees. Management of spring mulberry fields should focus on pest control to reduce the number of wintering pests. To ensure high quality and high yield of spring leaves. Due to the extremely low temperature in extreme cold weather in winter, the wintering mortality rate of mulberry fieldworm pests dominated by mulberry mulberries is low, and the base number is high, which occurs in large quantities in spring mulberry fields. According to surveys conducted at the beginning of April of each monitoring site, Mulberry was mainly based on 2-3 instars, with 280-3035 heads per mu and 826 heads per mu. The occurrence was 5.8 times that of the same period last year. At present, a few branches have started activities. Harmful mulberry buds. Sang plaster disease and scale insects occurred in the old mulberry gardens, and a few plots were seriously endangered. Last year, a few mulberry mulberry diseases occurred more severely. The pathogens overwintered in mulberry branches and soil. Once the climatic conditions are suitable, they will gradually spread to spread and spread. Agricultural control saw the piles of dead fists, pruning fine and weak branches, and brought them out of the mulberry field to burn out in time before the pests ran out. The mulberry tree with dry blight is cut off in time. Ploughing and weeding, it is clear that there is an unreasonable nesting within the mulberry garden. For non-fertilized plots, as soon as possible, supplement fertilizer with mainly available nitrogen fertilizer is applied. Renovate the ditch system so that the ditch is unobstructed, the differential level is clear, and irrigation can be performed. Manual killing of mulberry mulberry worms and larvae, clearing and killing indoor wintering mulberries.

Chemicals prevention and control Before April 20, all mulberry fields were treated with 90% methomyl WP 3500 times, with a safety interval of 12 days. Among them, the large-scale field of mulberry pods can also be treated with Parite 24% chlorfenapyr suspension for 2000 times (the chlorfenapyr is effective against ulnar pests, and the larvae and other pests are generally effective). Safety intervals It's 3 days. It was found that Sang Tianniu harmed the mulberry trees, and 80% of dichlorvos EC 50 times solution was injected into the boreholes to kill the larvae of S. tiansinensis. High-efficiency pesticides could not be injected into the boreholes to prevent residues and affect the safety of silkworms. Precautions Do not use pesticide varieties with unreliable quality. The 71% mulberry varieties must not use organophosphorus pesticides to prevent induced bacterial diseases. According to the standard preparation of liquid medicine to ensure the safety of medication. The spraying should be comprehensive, and the branches should be up and down, especially the mulberry punches must be all wet and spray thoroughly. Mulberry horses have more fields and can add 40% dimethoate EC 12ml to each barrel. In case of mulberry trees where mulberry diseases occur, the diseased branches and diseased leaves must be timely cut and incinerated and treated with mulberry disease regulators or mulberry disease inhibitors alternately, once a week for 2-3 consecutive times.
