Description
Technical field
The present invention is a kind of nematicide combination preparation, it is characterized in that containing iprodione composition, in order to overcome the resistance problem that iprodione Long-Time Service causes, with the addition of the Related Component that other are important.
Background technology
Root-knot nematode (Meloidogyne) is a kind of omnivorousness plant pathogeny line insect of height specialized form.The nematode of known vegetables of causing harm mainly contains high bow root-knot nematode, peanut root-knot nematode, M hapla, cucumber root-knot nematode, javanese root knot nematode and beet root-knot nematode etc.Nematode host range is extensive, and 30 various vegetables such as melon, the solanaceous vegetables of often causing harm, beans and radish, calabash radish, lettuce, Chinese cabbage, can also propagate some fungus and bacterium venereal diseases evil.
The control of nematode is a difficult problem in the world at present, much outstanding chemical agent was for many years once had once to play important effect, as high-toxic pesticides such as nemagon, phonamiphos, cadusafos, carbofuran, Aldicarbs, along with environmental requirement is more and more higher, these medicaments in succession limit and use or forbidding.Agriculturally prevent and treat nematode at present and substantially concentrate on prevention nematode to the invasion and attack of plant, after high-toxic pesticide forbidding, chemical control is only limitted to few several kind at present.Alternative low toxicity nematocide is little.Iprodione is a kind of low toxicity bactericide, respond well to a lot of fungal disease, and nematode is many times exist along with soil-borne disease bacterium simultaneously, simultaneously continuous cropping plot soil-borne disease bacterium and nematode spore are more serious for many years, simultaneously with the phenomenon such as soil compaction, land capacity degeneration.Find that iprodione has Plant nematode through test and certain kill activity, but iprodione is used alone, effect is not ideal enough, and easily brings out nematode and produce resistance, is unfavorable for continuing to control, but better effects if when adding other active components.
Summary of the invention
The object of the invention is to: a kind of low toxin preparation being applicable to agriculturally using is provided, not only nematode is had to better control efficiency, meets low toxicity and low residue simultaneously, has the function improving soil environment.
The present invention is achieved by the following technical solutions:
One kills nematode combination preparation, it comprises active ingredient and auxiliary agent (all the other are pesticide adjuvant composition), its active ingredient is iprodione and active component, described active component is the one in Avermectin B2, carbosulfan, nitrolim, fluorine pyrrole bacterium acid amides, amino-oligosaccharide, chlopyrifos, Imidacloprid, Affirm (Merck Co.), phoxim, mushroom polysaccharide, oligosaccharide, wax Bacillus, thick spore Verticillium dahliae, Paecilomyces lilacinus, and the gross mass percentage composition of described active ingredient in nematicidal agent composition is 1 ~ 90%.
The mass ratio of above-mentioned iprodione and active component is 60:1 ~ 1:60.
The formulation of above-mentioned preparation is suspending agent, aqueous emulsion, microemulsion, missible oil, wetting powder, water dispersible granules or granule.
Preferably, the gross mass percentage composition of above-mentioned active ingredient in nematicidal agent composition is 6 ~ 60%.
Select as one, above-mentioned active component is Avermectin B2, and the mass ratio of described iprodione and Avermectin B2 is 5:1.
