Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of compositions preventing and treating rice blast and preparation method thereof.
Background technology
Rotenone, universally present in the root bark portion of plant, is the material that a kind of specificity is the strongest, to insecticide especially in toxicology
It is that cabbage caterpillar, diamondback moth and aphid have strong tagging and stomach toxicity two kinds effect.Research in early days shows the work of rotenone
Mainly affect the Repiration of insecticide by mechanism, a certain composition mainly and between nadh dehydrogenase and ubiquinone occurs
Effect.Rotenone makes the electron transport chain of pest cell be suppressed, thus the ATP level reduced in organism finally makes insect
Can not get energy supply, then drumble, paralysis and slowly dead.
Rice blast is one of important disease of Oryza sativa L., can cause the significantly underproduction, and the underproduction 40%～50% time serious, even No kernels or seeds are gathered, as in a year of scarcity.
Ge Dao district of the world uniformly occurs.Primary disease all has generation in various places, wherein occurs as many with leaf portion, joint portion, can cause not after generation
With the degree underproduction, especially panicle blast or joint pestilence occurs early to weigh, and can cause dead ears so that having no harvest.In recent years, Guangdong rice blast year
Occurring area is no less than 500,000 mu, and occurs increasing trend year by year, and locally great outburst is much, and at present, rice blast may
There is any days in province territory, any season.
