Radishes planted in autumn and winter are susceptible to clubroot disease. The club root disease is characterized by the formation of tumors on the lateral roots. The main roots do not grow, do not swell, and are small in size. The shoots grow slowly, the plants dwarf, and the leaves wilt at noon, recovering early and late. The leaf color is chlorotic and yellow, plants wither and die, and the roots of the flesh have a bitter taste. Radish root cyst is a fungal disease. Its prevention and control methods are as follows: Before planting radish, use lime to disinfect the soil, use 75 to 100 kilograms per acre, spread it evenly in the soil, and then use ploughshare tillage to make it Full contact with the soil in order to eliminate various germs in the soil and adjust the soil to slightly alkaline, which is conducive to the growth of radish, and inhibit the propagation of germs. When radishes are grown, applying 400 to 500 kg per acre of cooked organic fertilizer as base fertilizer can effectively enhance the ability of radish to resist clubroot disease and reduce the incidence. In the seedling stage, combined with soil, apply 25-30 kg of 50% calcium cyanamide granules per acre and apply the soil after the application to protect the seedling roots from root tuberculosis. During root elongation of radish roots, an aqueous solution of 800 times Bacillus subtilis, or 800 times 50% aqueous solution of pentachloronitrobenzene, or 600 times 50% aqueous solution of sodium propionate, or 1000 times, is applied to the roots every 10 to 15 days. 25% fludioxonil aqueous solution, 1000 times 30% Famylline aqueous solution, 600 times 47% spring thunder-king copper aqueous solution, or 1000 times 25% methyllithophoric acid aqueous solution for prevention and control, continuous showering 2-3 Secondly, evenly soak the soil around the roots of the radish plant, and it is advisable to completely penetrate the soil around the roots without flowing out. In this way, radish will not be infected with clubroot disease. Corn Starch ,Corn Starch Heb,Bulk Corn Starch,Cornstarch Healthy Shanghai J.Shine Co.,Ltd , https://www.jshinechem.com
