Potato beetles are pests that seriously affect potato production. In order to effectively strengthen the interception, prevention and control of potato beetles, this plan is specially formulated. Encrypted investigation and monitoring scientifically arrange monitoring outlets in the occurrence area and the main potato production area to keep abreast of the occurrence and growth of epidemic situations. From May to September, during the period of adult migration and adult and larval harm, implement a regular reporting system to ensure early detection, early reporting and early extinguishment of the epidemic. Select representative host crop fields and wild host distribution areas in the occurrence area to carry out monitoring surveys, use GPS technology to accurately locate the occurrence field, and carry out unified prevention and control in a timely manner. In the incoming risk area, do a good job of monitoring the insect situation around the potato concentrated planting area, breeding base, vegetable trading market or distribution center. Eradicate the new epidemic situation, organize and carry out emergency prevention and control in time for the new epidemic situation, spray the pesticides on the plants in the center of the epidemic center and the surrounding area of ​​10 square meters, and remove and bury them manually. If possible, an 80 km wide biological isolation zone without potato beetle host plants should be established around the epidemic site to prevent the spread of potato beetles. Deeply turn over the soil at the epidemic spot (20 cm), cover with fumigated and pressurized soil, kill the pupae and adults in the soil, and prevent the potato beetle from escaping. Promote comprehensive prevention and control measures according to local conditions, take multiple measures, and scientifically carry out epidemic prevention and control. One is chemical prevention and control. For the epidemic outbreak area, seize the peak of the overwintering adult worm unearthed, the first and second generation larvae peak chemical control. The second is manual capture. Using the "false death" of the adult potato beetle, during the unearthed period of the overwintering adult in the spring, tissues were artificially captured and the leaves with egg masses were removed. The third is ecological governance. Rotation stubble is implemented to remove wild host plants such as celestial celestial beings and calyx solanum to reduce the occurrence area. During the sowing period, the mulching technology should be implemented according to local conditions to control the overwintering of adult insects. After harvesting, turn winter irrigation in time to reduce the base of overwintering. Strict quarantine inspection Strengthen the quarantine and quarantine of the origin, and strictly supervise the transfer of potato seeds and products. Jilin and Heilongjiang should step up quarantine inspection at the Potato Seed and Potato Breeding Center. Pay attention to strengthening the quarantine monitoring around the storage, transportation, processing and other places of the transportation of goods from the Russian Binhai New Area to prevent the spread of the epidemic with the relevant commodities.

Antibiotic:
A drug used to treat bacterial infections. Antibiotics have no effect on viral
infections. Originally, an antibiotic was a substance produced by one
microorganism that selectively inhibits the growth of another. Synthetic
antibiotics, usually chemically related to natural antibiotics, have since been
produced that accomplish comparable tasks.
Antimicrobial:
A drug used to treat a microbial infection(antibiotic drugs).
"Antimicrobial"
is a general term that refers to a group of drugs that includes antibiotics,
antifungals, antiprotozoals, and antivirals.
