草莓生产中,由于防治病虫害对化学药剂的过度依赖导致害虫或病菌的抗药性增强,而草莓的花果期又长达半年,在这个时期内进行药物防治,很难做到在农药的安全间隔期采摘上市,这会导致草莓采摘时的农药残留无法控制,安全品质也不能得到保证。因此,对草莓的病害症状以及发病规律进行分析,可为正确掌握防病技术提供参数与借鉴。1.灰霉病草莓的灰霉病主要为害其果实、
Strawberry production, due to pests and diseases of pesticides over-reliance on pesticides or pathogens led to increased resistance, and the strawberry fruit flowering period of up to six months, during this period of drug control, it is difficult to do in the pesticide safety interval Period picking and listing, which will lead to pesticide residues can not be controlled when picking strawberries, safety quality can not be guaranteed. Therefore, the analysis of the disease symptoms and pathogenesis of strawberry can provide parameters and reference for the correct control of disease prevention technology. 1. Botrytis cinerea strawberry gray mold mainly harms the fruit,
