“Can you come and see our cabbage? Ah, many die to death.” Huang Sheng, Lanxi Town, Heshan District, Yiyang City, gave a call to the author. After the late rice cultivation in this village, there has been a fine tradition of more than 20 years of cabbage cultivation. Although the time of the price is good, the farmers have not left this business. In particular, this year, the retail price of Chinese cabbage is RMB 5/kg, and the wholesale price has also reached RMB 3.2/kg. It is well planted. When one serving of vegetables is sold every day, you can get a colorful ticket. With low yields, my heart suddenly jumped.

I came to the village of Cao Yong, a new piece of cabbage, and I saw Lao Cao's cabbage has been dwarfed plants, leaf shrinkage, mosaic, such plants issued by a small, small, little commercial. Some plants were "planted", and the diseased plants were removed. No new roots were found. The stem bases or short-stemmed stalks of the outer leaves of the plants had soft rot. They were dark brown in color. If they were broken by hand, they were found to have festered and browned. The smell of strong pungent odor smells that the plants are no longer commercial. Although some people seem to have good growth, scattered grayish-white near-circular lesions are commonly found on leaves. The lesions are about 6 to 10 mm in diameter, and the lesions are severely white, translucent and roasted like fire.

I saw the author watching slowly in the field, Cao Yong new side already anxious not.

"Your cabbage has at least three kinds of diseases." The author said, "The leaves are shriveled and mosaics are viral diseases. It is caused by locust transmission. The main reason is that in the high-temperature nursery in September, there were many locusts and no timely prevention and treatment. In November and December, when warm winters are encountered, prevention and control should be strengthened, and they can be controlled by imidacloprid, Aketai and other agents. In addition, the virus A, virus K and other agents should be sprayed to prevent spread.”

“This type of cabbage is a soft rot that you picked up. You smell and smell bad.” Soft rot is also a common disease in cruciferous vegetables in autumn and winter, and it is generally popular in rainy seasons. , serious can lead to devastating losses. Lao Cao's cabbage was made of sorghum and there was no stagnant water in the field, so there was not much happening. Otherwise, the entire field would have been destroyed. If this happens, we must remove the diseased plant in time and bury it deeply in the hole. Apply lime and spray or root with streptomycin sulfate or neomycin to prevent further spread. In early Daejeon, 100 to 150 kilograms of lime should be applied during the plowing. The planting density should not be too large, and weeding should be done in time to make the fields breathable and cool. "No wonder the next-door cabbage has applied lime. It really does die less." Lao Cao muttered next to him.

"The large gray lesion on the leaves is white spot disease, although it does not cause a large reduction, but it can not be ignored, can use carbendazim, thiophanate-methyl and other broad-spectrum agents to control two or three times." The author pointed Those gray spots that are obvious on the blades say.

"Help me write down these drug names, okay, I'll buy drugs right away." Lao Cao nodded as he listened, wrinkled brows showed signs of stretch.
