Embodiment 1

[0037] This embodiment provides a comprehensive prevention and control method for litchi downy mildew. The method is aimed at the four important growth stages of litchi spring shoot stage, flower bud stage, young fruit stage and fruit development later stage, and is carried out on litchi downy mildew. The four control measures of early disease monitoring, agricultural control, chemical control and biological control are integrated and assembled to construct comprehensive control measures for litchi downy mildew suitable for each growth stage, which specifically includes the following steps:

[0038] (1) Litchi spring shoot stage: Use PCR technology to monitor the early occurrence and damage of litchi Phytophthora without obvious symptoms; pruning dense branches to ensure ventilation and light transmission; keep the soil loose and breathable, clear ditches in rainy seasons to facilitate drainage Wet; scientific fertilizer, mainly organic fertilizer; according to the disease moni...

Embodiment 2

[0043] This embodiment provides a comprehensive prevention and control method for litchi downy mildew. The method is aimed at the four important growth stages of litchi spring shoot stage, flower bud stage, young fruit stage and fruit development later stage, and is carried out on litchi downy mildew. The four control measures of early disease monitoring, agricultural control, chemical control and biological control are integrated and assembled to construct comprehensive control measures for litchi downy mildew suitable for each growth stage, which specifically includes the following steps:

[0044] (1) Litchi spring shoot stage: PCR monitoring in the early stage of disease, cut off diseased branches, clear ditches in rainy season, and apply organic fertilizer; according to disease monitoring, spray 70% mancozeb wettable powder 500-800 times liquid in litchi spring shoot stage 1 time.

[0045] (2) Litchi flower bud stage: PCR monitoring in the early stage of disease, cutting o...

Embodiment 3

[0049] This embodiment provides a comprehensive prevention and control method for litchi downy mildew. The method is aimed at the four important growth stages of litchi spring shoot stage, flower bud stage, young fruit stage and fruit development later stage, and is carried out on litchi downy mildew. The four control measures of early disease monitoring, agricultural control, chemical control and biological control are integrated and assembled to construct comprehensive control measures for litchi downy mildew suitable for each growth stage, which specifically includes the following steps:

[0050] (1) Litchi spring shoot stage: early PCR monitoring of disease, clearing ditches in rainy season to facilitate drainage and dehumidification; apply organic fertilizer; according to the monitoring situation, use 500-800 times liquid of chemical control 70% mancozeb wettable powder on litchi Spray once in spring shoot.

[0051] (2) Litchi flower bud stage: PCR monitoring in the early...

Abstract

The invention discloses a comprehensive prevention and control method for peronophythora litchii, which is characterized in that four prevention and control measures of early disease monitoring, agricultural prevention and control, chemical prevention and control and biological prevention and control are integrated and assembled for the peronophythora litchii aiming at four important growth stages of a spring shoot stage, a flower bud stage, a young fruit stage and a later fruit development stage of litchis. And a comprehensive prevention and control measure suitable for the peronophythora litchii at each growth stage is constructed. According to the invention, the modern molecular biological technology PCR is used for monitoring and then guiding prevention and control, so that the occurrence of the litchi peronophythora blight is more effectively prevented and controlled, the prevention and control effect is more obvious, the comprehensive prevention effect on the litchi peronophythora blight is more than 90%, and the yield and quality of litchis are improved. According to the method, measures such as disease monitoring, agricultural prevention and control, chemical prevention and control and biological prevention and control are comprehensively adopted, the litchi peronophythora blight is effectively prevented and controlled, the use frequency and the use amount of pesticides are remarkably reduced, and the method has great significance in litchi industry development and environmental protection.

Description

technical field [0001] The invention belongs to the field of crop disease prevention and control, and relates to a comprehensive prevention and control method for litchi downy mildew. Background technique [0002] Lychee downy mildew caused by Peronophythora litchii is one of the most important diseases of litchi, which seriously affects the yield, quality, storage, transportation and export of litchi. The disease was first reported in Taiwan, my country in 1978. Lychee downy mildew is currently occurring in Fujian, Guangdong, Guangxi, Hainan, Yunnan, Guizhou, Sichuan, Taiwan and other places. shoots, leaves, flower spikes, fruiting twigs, fruit stalks and young fruits, causing a large number of fruit drop and rotten fruit, yield loss of up to 80% or more, or even no harvest, resulting in huge economic losses. In recent years, the epidemic frequency and prevalence of the disease have gradually increased, and it has become an important obstacle to litchi production. [0003]...
