Abstract

The invention discloses a comprehensive prevention and control method for soft rot of kiwi-fruit. The method comprises the steps of clearing an orchard in winter, carrying out prevention by using reasonable pesticides before germination in spring and at an initial stage of flower buds, carrying out flower strengthening, carrying out prevention and control by using reasonable microbicides and insecticides after 80% to 90% of flower drop, carrying out fruit setting for 10 to 30 days, treating young fruits by using microbicides and a plant growth regulator in a fruit soaking manner, then, carrying out bagging, carrying out unbagging after fruit picking, and rapidly spraying microbicides. According to the method, the infection of pathogenic bacteria of the soft rot of the kiwi-fruit is hindered by fruit bagging bags, and the bagging bags with light transmittance are used, so that the photosynthesis of the fruits during growth is guaranteed, and the quality of fruits is ensured. If baggingis carried out by using plastic films, the increase of fruit picking and grading efficiency is facilitated. According to the method, on the premise of guaranteeing the quality of fresh kiwi-fruit fruits, the soft rot of the kiwi-fruit is efficiently solved, the consumption of pesticides is reduced, and thus, the method is particularly applicable to the germination stage, blooming stage, young fruit stage and fruit swelling stage of the kiwi-fruit in continuous-rainy and high-humidity regions.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a comprehensive prevention and control method for kiwifruit soft rot. Background technique [0002] Soft rot of kiwifruit is another major disease that endangers the kiwifruit industry in China in recent years. In recent years, it has commonly occurred in the main producing areas of kiwifruit in Guizhou, Sichuan, Shaanxi, Jiangxi and other provinces, causing great harm to fruit quality and postharvest storage and transportation. In the early 1980s, the disease was reported in New Zealand, Italy and other countries. At present, Botryosphaeria dothidea and Phomopsis sp. are found to be the main pathogens of the disease in countries including China, Japan and South Korea. The above-mentioned two kinds of pathogenic bacteria live through the winter on the branches with mycelium, conidia and ascus. The main routes of transmission are wind-borne and rain-borne, and insect...
