山东省露地辣椒病虫害的化学防治及高产稳产策略

Chemical Control of Pests and Strategy on Pepper Stable-yield and High-yield Production in Open Fields of Shandong Province

近年来,山东省露地辣椒种植面积不断扩展,已成为重要的经济作物之一。然而,高复种指数、幼苗带菌、高温多雨的气候条件等因素加重了辣椒病虫害的发生,尤其是辣椒炭疽病的防治难度增大,严重制约了辣椒产业的发展。本文综述了辣椒病虫害的发生规律和化学防治手段研究进展。根据本课题组多年从事辣椒病虫害防治的工作经验,结合药剂的登记现状,阐述了对辣椒病虫害高效、有序控制的看法,并提出了一套切实可行的高产稳产策略。

In recent years,the growing area of pepper in open field has gradually increased in Shandong province and pepper has become one of the most important economic crops.However,high multiple cropping index,seedling pathogen,high-temperature and wet climate conditions lead to the heavy occurrence of pests on pepper.Specially,pepper anthracnose,which was hard to be controlled,has severely restricted the development of pepper industry.The occurrence rules of pests on pepper were reviewed in this paper and the research progress in chemical control was also described.Based on many years＇ experience on pest control,the authors have elaborated the the points on the efficient and orderly control of pepper pests combined with the registration status of pesticides,and presented a serials of practical strategies for pepper high-yield and stable-yield production.
