Abstract
The invention discloses a bactericide composition. The effective components of the bactericide composition include prochloraz and a plant extract, the weight ratio of the prochloraz to the plant extract is 1:2-16, the plant extract is the mixture of a tuber fleeceflower stem extract, a pseudolarix amabilis bark extract, a curcuma zedoary bark extract and a szechwan Chinaberry fruit extract, and the weight ratio of the tuber fleeceflower stem extract to the pseudolarix amabilis bark extract to the curcuma zedoary bark extract to the szechwan Chinaberry fruit extract is 0.5-3:1-2:1-2:4-6. The prochloraz and the plant extract are compounded to ensure that the activity of the composition is more remarkable than that of prochloraz used alone, the bactericidal effect is good, the effect is fast, and the prevention and control effect is more lasting. In addition, the bactericide composition is safe to crops, stable in chemical property and safe, the environmental destruction brought by a chemical pesticide is reduced, and residual harmful ingredients of soil are decreased.
Description
Technical field
The invention belongs to bactericide technical field, be specifically related to a kind of microbicide compositions.
Background technology
For a long time, chemical pesticide control damage by disease and insect, because it is efficient, quick-acting, cheap and easy to use, is in monopolization in place in plant protection.Along with the people are to pay attention to day by day that is healthy and environmental problem, chemical pesticide enjoys people to query because of problems such as it is residual, environmental pollutions.Particularly directly affect the healthy food of people, " Green Trade Barrier " has been carried out in countries in the world, limits the residual quantity of chemical pesticide.Therefore, less with chemical pesticide and find alternative chemical pesticide and carry out disease control and become the emphasis studied in the future.
Prochloraz (Prochloraz) Prochloraz is a kind of wide-spectrum bactericide, has obvious preventive effect to the disease that various crop is caused by sac fungi and imperfect fungus.To the multiple diseases on field crop, fruit and vegetable, turf and ornamental plants, there is treatment and eradicant action.Work by suppressing the biosynthesis of sterol, in plant corpus, have Uptake and translocation effect, the multiple diseases preventive effect caused for sac fungi and imperfect fungus is splendid.In Prochloraz, absorption is strong, and quick-acting is good, and the lasting period is long.
Traditional bactericide, mostly is chemical agent, and this kind is only by the bactericide that chemical agent is composite, although bactericidal effect is fast, environmental pollution is serious, and soil residual quantity is many, harm human and livestock health.
Summary of the invention
For the defect existed in prior art, the object of this invention is to provide a kind of microbicide compositions.
Described a kind of microbicide compositions, it is characterized in that being made up of active ingredient Prochloraz and plant extracts, the weight ratio of described SSF 126 and plant extracts is 1:2-16, described plant extracts is the mixture of Polygonum multiflower knotweed stem extraction, native rose of Sharon stem and bark extract, curcuma zedoary stem and bark extract, Fructus meliae toosendan berry extract, described Polygonum multiflower knotweed stem extraction: native rose of Sharon stem and bark extract: curcuma zedoary stem and bark extract: the weight ratio of Fructus meliae toosendan berry extract is 0.5-3:1-2:1-2:4-6.
