Abstract
The invention relates to pesticide composition containing fluensulfone and fluoxastrobin. The pesticide composition comprises effective components including fluensulfone and fluoxastrobin, and the balance of auxiliary components which are available and acceptable in pesticides, a ratio of fluensulfone to fluoxastrobin in parts by weight is (1:20)-(20:1), and the total weight of fluensulfone and fluoxastrobin is 5%-50% of the weight of the pesticide composition. The pesticide composition is mainly used for controlling cucumber root-knot nematode diseases and seedling diseases, and indoor antibacterial tests and field tests indicate that the pesticide composition has a very high control effect on root-knot nematodes, especially cucumber root-knot nematodes, and is a compound preparation worthy of popularization.
Description
Technical field
The present invention relates to a kind of compounded preparation of pesticide, its active ingredient is fluorine alkene line sulfone, the phonetic bacterium of fluorineEster, for preventing and treating cucumber root-knot nematode.
Background technology
Fluorine alkene line sulfone (fluensulfone) belongs to non-stifling novel nematicide, raw to eachThe nematode in long stage all has good prevention effect. The mode of action of common non-fumigating nematicideBe to make nematode lose ability to act, but after a period of time, nematode can recover, fluorine alkene line sulfone isNematode is thoroughly killed. The time that fluorine alkene line sulfone enters soil is only 12 hours, and its homicideThe time that nematode agent enters soil is generally about 5 days.
Fluoxastrobin (fluoxastrobin) belongs to methoxy acrylic bactericide, and fluorine is phoneticThe mechanism of action of bacterium ester is also mitochondrial respiratory inhibitor, passes through at cytochrome b and C1Between electronics shift suppress mitochondrial breathing. Fluoxastrobin application optimum period, is wide, no matter invades fungiDye early stage as spore germination, germ tube growth and invade leaf portion, still can at growth period of hyphaExtraordinary protection and therapeutic action are provided; But infect the most effective to spore germination and initial stage. CauseThe excellent systemic activity having, it can be rapidly absorbed, and can be in leaf portion equably to topTransmit, therefore there is the resistance of rainwater washing against ability that root is good.
At present the nematode of the known crop of causing harm mainly contain high bow root-knot nematode, peanut root-knot nematode,North root-knot nematode, Meloidogyne incognita, javanese root knot nematode and beet root-knot nematode etc.Nematode host range is extensive, melon, the solanaceous vegetables of often causing harm, beans and radish, calabash radish, lettuce30 various vegetables such as lettuce, Chinese cabbage, can also propagate some fungus and bacterium venereal disease evils.
Mainly the cause harm root of various vegetables of root-knot nematode, shows as lateral root and fibrous root compared with normal and increasesMany, and on the fibrous root of young root, form the spherical or conical white root nodule differing in size, haveBe beads shape. Short and small, slow, the leaf color anomaly of killed strain overground part growth, result is few, outputLow, even cause plant dead ahead of time.
Fluorine alkene line sulfone and fluoxastrobin are mixed for preventing and treating cucumber root-knot nematode at present without report.
Summary of the invention
The object of the present invention is to provide a kind of composite increasing that contains fluorine alkene line sulfone and fluoxastrobinEffect composition, for preventing and treating cucumber root-knot nematode.
Technical scheme: for achieving the above object, the invention provides one and contain fluorine alkene line sulfone and fluorineThe composition pesticide of Fluoxastrobin, active ingredient is fluorine alkene line sulfone and fluoxastrobin, fluorine alkene line sulfone andThe weight ratio of fluoxastrobin is 20:1～1:20, and fluorine alkene line sulfone and fluoxastrobin weight summation existPercentage by weight in composition is 5%～50%, and all the other use and can connect for allowing in agricultural chemicalsThe auxiliary element being subject to.
Described composition pesticide can be according to well known to a person skilled in the art method, is mixed withGranula, microcapsule suspending agent, suspending agent.
Described composition pesticide also contains in the required agricultural of preparation pesticidal preparations acceptableInsecticides adjuvant, be selected from solvent, wetting agent, emulsifying agent, dispersant, disintegrant, binding agent,In filler, macromolecule cyst material, pH adjusting agent, thickener, defoamer, carrier etc.One or more, be known substance, be various auxiliary agents conventional in pesticidal preparations, according toDifferent situations can change to some extent, are not particularly limited.
The production technology of described composition pesticide application forms all belongs to existing known technology, at thisRepeat no more.
Composition pesticide provided by the invention, is applied to control cucumber root-knot nematode.
Compared with prior art, the invention has the advantages that:
1, fluorine alkene line sulfone and fluoxastrobin are composite has a beyond thought synergistic function, thanSingle dose is used separately the prevention effect having improved insect and germ;
2, fluorine alkene line sulfone and the fluoxastrobin mechanism of action are different, mixed can delay insect andThe drug-fast generation of germ;
3, two kinds of active ingredients of fluorine alkene line sulfone and fluoxastrobin are composite, reduced agricultural chemicals use amount,Reduce use cost and alleviated the pollution to environment.
Detailed description of the invention
