Description

technical field [0001] The present invention relates to a soil conditioner product, more particularly, the present invention relates to a soil conditioner for controlling clubroot of cruciferous crops. Background technique [0002] Cruciferous crops are an important vegetable group in my country. Due to the damage of clubroot, many diseased areas can no longer grow cruciferous vegetables, which seriously affects the production, life and economic benefits of farmers. Experimental studies have shown that the pathogenic bacteria of clubroot of cruciferous crops is the fungus of the genus Plasmodium brassicae of the class Flagellate. Mainly waterborne. The long-distance spread is the seed with bacteria, and the commercial vegetables with bacteria are transported and spread. [0003] Clubroot of cruciferous crops was first discovered in Zhejiang Province in 1950, and has now spread to 12 provinces (cities, districts) across the country. The damage is becoming more and more seri...

Problems solved by technology

Only three kinds of chemical pesticides such as domestic chlorothalonil and Japanese nebizin have obvious control effects, but they need to be watered or sprayed, and the pesticides are applied on the surface of the plow layer. Multiple times of pesticides are needed in one growth cycle of crops. The dosage per mu is 2-8 kg, and the control effect can reach 60-80%. However, the control cost per mu is 120-238 yuan, and the use method is limited by the production level and conditions, so it is difficult to popularize and apply it on a large scale.
