Description
Technical field
The invention belongs to technical field of pesticide, are related to composition pesticide, and in particular to a kind of agriculture for preventing and treating citrus bacterial canker disease
Drug composition.
Background technique
Citrus is as the favorite fruit of people, and with the propulsion of high-efficiency agriculture, industry production is rapidly developed, and cultivated area is fast
Speed expands, and increases citrus bacterial canker disease pathogen radix in orchard year by year, and then citrus bacterial canker disease is caused to be on the rise.Mandarin orange
Tangerine canker will cause treetop ulcer lesion, and blade is largely fallen ill, fruit rind deformity, ulcer, seriously affect fruit appearance and
Mouthfeel loses edible value.Can also field be caused to be lost simultaneously, or even cause to seriously endanger in the storage and transport of fruit.
For the prevention and treatment of citrus processing, there are no effect good control measures and method at present.At this stage during Orange Producing
Main control measure to canker is still the means such as sprinkling chemical agent, but since long-term uses chemical drugs to burst
Ulcer germ produces drug resistance to various sterilization agent, simultaneously because high-intensitive uses pesticide, results in pollution environment and peasant
A series of problems, such as drug cost increases.
It is current development pesticide new product and prevention and treatment resistance disease that the pesticide active ingredient of different role mechanism, which is carried out compounding,
A kind of effective quick way of bacterium.After different pesticide active ingredients are compounded, three kinds of type of action can be shown: being added and make
With, synergistic effect and antagonism.In general, only by after largely testing and capable of just learning different pesticide active ingredients compounding
