• selection of resistant varieties: selection of more resistant varieties such as zheng potato 5, zin quo 8, netherlands 3, chinese potato 3, etc. • strict quarantine: quarantine of origin is strictly applied for seeding, as well as the testing of potatoes and the prohibition of seeding from the sick areas. • choosing non-pathic potato: sowing the whole potato, avoiding scissor transmission, using small seeding methods, increasing the yield rate and reducing the incidence. • choosing of sunburn: the seeding of potatoes is laid outside the room before sowing, and the sprouts cause visible symptoms of the cassava to be phased out. • sterilization of cycling diseases: circulatory diseases are mainly transmitted through scissors, with the preparation of two cutches, a pot of potion, the cutting of tails for observation on the basis of the elimination of sick chips, the phasing out of disease, the elimination of disease-free species, the removal of a chip in exchange for a knife, the use of disinfectant water for 0. 1 to 0. 2% litres of mercury fluid, 5% cyrate, 0. 1% potassium permanganate, 0. 5% salt water, 75% alcohol. • sterilization containers: packagings may be evaporated, high-temperature disinfection or copper sulphate treatment, and agricultural machinery may be used for bleaching solutions or ff. • medicinal impregnation of potatoes: circulosis is present in cavity cassiterites, common drugs make it very difficult to kill bacteria inside the chips, and 200 mg/kg thioacin, cythin or mercury-leaving chips are commonly used in production. Potato chips are impregnated for 5 minutes with 50% more than 800-1,000 times more vinyl or 80% more than 1,500 times ethylene emulsion, 2000 times more with new corin, 47% more than 500 times more with humid powder (cronin + copper chloride). • medicinal control: at the beginning of the onset of the disease, the use of sulphate or 72 per cent of the agrosulphate sulphate soluble powder 4000 times the fluid or 25 per cent of the ammonium copper water agent 500 times the fluid, 77 per cent of which can kill the wettable particulate powder 400-500 times the fluid, 50 per cent of the bacterial humid powder 400 times the fluid, 47 per cent of the garine humid powder 700 times the root, 0. 3-0. 5 l, one in 10 days, and 2-3 consecutively. • prevention and control of agriculture: potato cultivation should be carried out in a rotational manner, with the whole area torn apart and the source of the winter bacteria eliminated. At the same time, field management is being strengthened, pest and disease control is being carried out, manure management is being strengthened and the capacity of potatoes is being improved. • field management: long-term, long-term pine, earth-breeding, water-watering, grass-brawling, rational fertilization, field-based fruit and tiring, increased potato capacity for fertilizing, increased immuno-prevalence and improved potato productivity. The above-mentioned integrated response allows for effective control of the occurrence and spread of potato cyclic disease。
