Pollution-free control methods and techniques for sclerotinia disease of coriander
1. Agricultural control (1) Practice crop rotation or high-temperature control. In diseased fields, practice a 2-3 year rotation with grain crops, or a 1-year rotation with rice or with aquatic vegetables. Where protected cultivation land cannot be rotated, high-temperature control may be adopted, as follows: during the high temperatures of the three summer months, first clean the field, remove diseased leaves and stems and weeds, carry them out of the field and bury them deep or burn them; apply 50-100 kg of lime per 666.7 sq m, add 500 kg of chopped rice straw or wheat straw, spread evenly on the surface, immediately turn into the soil, form high ridges about 30 cm tall, and fill the furrows with water until saturated; to keep water in the furrows at all times, irrigate every day; cover with plastic film, seal the edges tightly with soil, and keep the greenhouse or room closed for 15-20 days. This method can not only kill the lower sclerotia, but also kill pathogens such as Fusarium and root-knot nematodes.
