Method for preventing and controlling radish seed plant diseases

Abstract

The invention discloses a method for preventing and controlling radish seed plant diseases, and the main diseases are black spot disease, black rot disease and soft rot disease. Specifically, the method includes the steps of (1) prevention and control in a vegetative growth period: removal of old leaves: removing old radish leaves; loosening of soil: in the middle of radish vegetative growth, turning the soil for a soil zone where each radish is planted, filling in with sandy soil mixed with zinc, manganese particles and lime; water control; and spraying of chemicals; (2) prevention and control after the end of the vegetative growth period: selecting harvested radish seed plants with the diameter of the epidermis lesions less than or equal to 3.2 cm for prevention and control; and first cleaning infected parts, then carrying out initial sterilization and dipping and absorption, then subjecting the infected lesions to electrode induction treatment, and finally applying the infected parts with mixed powder; and (3) field planting. The method of the invention effectively solves the problems of material loss and the like due to that fleshy roots are infected by fungal diseases and bacterial diseases in the vegetative growth period and winter storage period of radish seed plants, solves the problems existing in the prior art, and satisfies the practical use.

Description

technical field [0001] The invention relates to a method for preventing and controlling radish seed plant diseases, and belongs to the technical field of vegetable disease and insect pest control. Background technique [0002] Radish is an important vegetable crop that originated in my country. The ecological environment in my country is complex and diverse, and radish germplasm resources are very rich. Although the country pays more and more attention to the protection of radish germplasm resources, with the popularization of fine radish hybrid varieties and the change of farmers' planting habits, many high-quality radish germplasm resources that have not been collected and preserved by breeders in time are gradually disappearing , so there is an urgent need to protect and utilize these radish resources. In the process of collection and storage, the fleshy roots of radish are easily infected by major diseases, resulting in the loss of scarce materials. At present, the pre...
