Rapeseed virus disease

In recent years, rape virus disease has occurred in all regions of rapeseed production in the country. In the rapeseed on Brassica napus, there have been systemic types of spotting. Old leaves have early onset and symptoms are evident, and they spread to new leaves. At the time of initial onset, a pinpoint-sized transparent plaque was produced, which expanded into a nearly circular 2 to 4 mm macula. The center was dark brown withered and dead spots, and necrotic spots were stained around. Black and black fusiform to long stripe lesions appeared on the vegetable stems, and spread from the lower part to the branches and fruit stems. Lateral lesions on the stems were mostly split or horizontal, and flowers and pods were easy to wilt or die. The pods produce black dead spots and are often malformed. The pathogen is mainly turnip mosaic virus, which often reduces rapeseed production by 50% to 60%. The virus is mainly transmitted by locusts. The rapeseed cultivation area is dry or drizzle in autumn or spring and the temperature is high, which is conducive to the occurrence of locust infestation and migration of winged maggots. The disease is easy to occur and prevalent. Early sowing or transplanted rapeseed in spring and late spring rape are susceptible to disease.

Prevention and control of the disease mainly take the following measures: Antivirus disease should be adapted to local conditions to select rape varieties resistant to viral diseases, such as the resistance to turnip mosaic virus Ningyou 7, glycerol 5, oyster sauce 12, oyster sauce 13, Xiangza Oil No. 1, Rongyou No. 3, Yuyou No. 2, Zhongshuang No. 4 and other varieties.

Rapeseed field as far away as possible from cruciferous vegetable fields. Curing disease prevention. Timely use of dimethoate, 20% cyanogen, horse cream and other drugs to treat aphids. In the early stage of disease, spray 0.5% anti-virus mushroom proteoglycan hydrolysate 300 times solution or 10% virus king WP 500 times solution, or 1.5% plant disease emulsifier 1000 times solution, 83 agent increase agent 100 times solution , every 10 days, continuous control of 2 or 3 times.
