Do a good job of disease prevention
The diseases at the adult stage include viral diseases, bacterial wilt, scab, anthrax, gray mold, epidemic diseases, blight, and some physiological diseases. Among them, scab and bacterial wilt are bacterial diseases, anthrax, and gray mold. Diseases such as epidemic disease and blight are fungal diseases.
Virus disease originated in the middle and late May of Changsha, and it was prosperous in June and July. After a high-temperature drought in August, the condition became worse.
Control by the following methods. Select disease-resistant varieties; soak the seeds with clean water for 3 to 4 hours, and then soak in 10% trisodium phosphate solution for 30 minutes. Rinse and rinse after germination; control aphids; use A600-800 times virus or virus Fly 600 to 1000 times or virus 600 to 800 times liquid spray control.
Scab disease is prone to high temperatures and rain, which began in late May and peaked in June. It stopped at the end of the July rainy season. The main damage to the leaves, the initial emergence of spots on the back of the leaves, water stains, enlarged lesions after the irregular shape, the circumference slightly elevated, dark brown, lighter internal color, slightly concave, surface roughness was scab-like, and then leaves off. It can also harm stems and fruits.
In the early stage of disease, spraying prevention and control in time, using 80% dexamethasone wettable powder 700 times liquid, or Bordeaux mixture, once every 7 to 10 days 1 continuous control 2 or 3 times.
Bacterial wilt began to occur in May and June and the most serious occurred in July. Affected by the acid, alkalinity and variety of the soil.
The disease is locally infested and the entire plant is onset. At the early stage of disease, the entire plant or part of the plant wilted at noon and recovered in the early evening. It did not recover after 2 to 3 days and remained green when dead. Slightly immersed in a small section of diseased stems in water, a little can be seen that the fog gush (all bacteria pus). It is different from capsicum wilt or infective root rot.
Spotted sporadic strains were removed immediately. The cavities were sterilized with 2% formalin or 20% lime water to prevent the spread of soil bacteria. When contiguous, application of 100-200 mg / kg agricultural streptomycin or neophytin root. Irrigation liquid per strain 0.25 ~ 0.5 kg, irrigation every 10 to 15 days, 2 or 3 times in a row. Irrigation at the same time, spraying liquid medicine such as: 50% green milk copper emulsion 500 times or 14% ammonia water copper liquid 300 times, 77% can kill WP 500 times, 72% can be streptomycin for agriculture Wet powder 4000 times. Every 3 to 7 days, continuous spraying 2 to 3 times. Phortonone and Segoxin are new drugs that have a good control effect in the past two years.
