Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the examples.

[0014] (1) Take 50 catties of waste molasses produced by the sugar factory, 20 catties of garlic, and 50 catties of water, mix them, pack them in plastic barrels or other containers, seal them for anaerobic fermentation, and use them within 10 months.

[0015] (2) Weigh 3 catties each of Eucommia ulmoides leaves, Eucommia chinensis, black ink grass, and comfrey, soak them in 100 catties of 50-degree wine, and soak them for 5 months before use.

[0016] (3) Take the above garlic fermentation liquid and medicinal wine and mix according to the ratio of 1.5:1 to get the finished product.

[0017] When in use, add water at a ratio of 1:100 to the drug, and then spray it.

[0018] If it is used to prevent pests, it can be prepared by adding water at a ratio of 1:200 and spraying.

Abstract

The invention relates to a biological agent for citrus canker pest control. The biological agent is prepared from raw materials in parts by weight as follows: 50 parts of molasses, 20 parts of garlic and 50 parts of water, the materials are mixed and subjected to anaerobic fermentation; folium eucommiae, herb of savatier monochasma, yerbadetajo herb and radix arnebiae are soaked in liquor, garlic fermentation broth is mixed with the medicinal liquor, water is added, and the product can be used. The biological agent is a non-toxic and residue-free strong biogenic bactericide and has a special effect on canker, after application for 12 h, a dark brown greasy outer ring and a yellow halo ring on periphery of each disease spot start darkening, after application for 24 h, the dark brown greasy outer ring and the yellow halo ring on the periphery of each disease spot are dehydrated, wrinkled and recessed, holes are formed in part of disease spots on the fourth day, and no new canker point is formed when observation is performed on the tenth day. The control effect can reach 90% or higher, and the biological agent is safe to fruit trees and environment-friendly. The biological agent not only can control citrus canker effectively, but also can kill pests such as red spiders, aphids and the like, has the characteristics of rich resource and low cost and is easy to popularize and implement.

Description

technical field [0001] The invention relates to the field of biological pesticide preparations, in particular to a biological agent for controlling citrus canker disease and insect pests. Background technique [0002] Citrus is an important tropical and subtropical fruit, and its production is widely distributed. There are 145 countries producing citrus in the world, and its output ranks first in the world. China is the world's largest producer of citrus. It is widely cultivated in 19 provinces (cities, districts) in mainland China. Like other crops, citrus is also damaged by various pests and diseases. Currently, the most serious damage to citrus in my country is Huanglongbing and canker. Both diseases are quarantine bacterial diseases. Citrus canker is a bacterial disease caused by Xanthomonas axonopodispv. citri (Hasse) Vauterin et al. The pathogen mainly infects Rutaceae plants, and sweet oranges, navel oranges, limes and other varieties are the most susceptible. It ma...
