Abstract
The invention relates to a pesticide compounded preparation comprising the active compositions fosthiazate and difenoconazole and used to control cucumber root knot nematode disease and seedling-stage diseases. Indoor bacteria-inhibiting tests and field tests prove that when fosthiazate and difenoconazole are compounded according to the ratio of 3:1-10:1, the drug-effect reducing case does not appear, relatively good purpose of governing diseases and insects is realized, the drug application frequency is reduced and the labor cost is effectively saved. A particulate agent is prepared according to the ratio, and a lot of field tests prove that the compounded preparation of fosthiazate and difenoconazole has extremely high controlling effect on cucumber root knot nematode disease and seedling-stage diseases, and is a compounded preparation worth popularizing.
Description
Technical field
The present invention relates to a kind of composition pesticide, active ingredient is fosthiazate, Difenoconazole, for preventing and treating cucumber root-knot nematode and sprout term disease.
Technical background
Fosthiazate has tags and systemic action, and toxicity is lower, and to root-knot nematode, pratylenchus has special efficacy.Kill nematode scope wide, to root-knot nematode, pratylenchus, stem eelworm, Cyst nematode etc. have good control efficiency, fosthiazate has excellent performance of tagging, when using dosage reaches recommendation consumption, medicament, once contact the dead wire worm that just can tag with nematode, has strong Uptake and translocation effect in plant, can in effectively preventing nematode invaded plants body, also can effectively kill the nematode in intrusive body.Simultaneously to overground part insect, as to aphid, tetranychid, thrips etc. also have doublely controls effect, and it is long to kill the nematode lasting period, annual crop 2-3 month, perennial crop 4-6 month.Kill nematode effect not by the impact of soil temperature.
Difenoconazole is that in triazole bactericidal agent, safety is higher; Difenoconazole has protection, treatment and systemic activity; it is sterol demethylation inhibitors; the biosynthesis of T suppression cell wall sterol; stop the growth of fungi; fungicidal spectrum is wide, and leaf surface treatment or seed treatment can improve output and the guaranteed quality of crop.
Summary of the invention
The object of this invention is to provide a kind of composition pesticide simultaneously can preventing and treating cucumber root-knot nematode and sprout term disease.
The object of the invention is to be achieved through the following technical solutions: a kind of composition pesticide containing fosthiazate and Difenoconazole, active ingredient is fosthiazate and Difenoconazole, the ratio of quality and the number of copies of fosthiazate and Difenoconazole is 3:1 ~ 10:1, and optimum quality portion rate is 5:1.
Described composition pesticide can adopt known processing technology, selects suitable insecticides adjuvant, is processed into the application forms of applicable agricultural use, preferred particulates agent in the present invention.
The insecticides adjuvant used in composition pesticide of the present invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, pH adjusting agent, defoamer, antifreezing agent, deionized water, filler etc., all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption, according to recipe requirements, are determined through simple test.
Composition pesticide of the present invention, for preventing and treating the composition pesticide of cucumber root-knot nematode and sprout term disease, can reach the object that desirable sick worm rules, reduce times for spraying, effectively saved labor cost, be a kind of be worthy to be popularized sterilization, disinsection compound preparation.
Technology origin of the present invention: the present inventor has carried out symphyogenetic development test to fosthiazate with the mixed of Difenoconazole.
Evaluate drug combination mode according to Gowing method, its formula is as follows:
E
0﹦X﹢Y–XY/100。
In formula, X be fosthiazate alone with certain dosage time control rate to target pest; Y be Difenoconazole alone with certain dosage time to target fungus inhibiting rate; E
0for the theoretical value to target inhibiting rate when fosthiazate, Difenoconazole two kinds of pharmacy mix; Measured value to target inhibiting rate when E is fosthiazate, Difenoconazole two kinds of pharmacy mix.
Evaluation criterion: as E – E
0during > 10%, be expressed as synergistic effect; As ﹣ 10%≤E – E
0when≤10%, show as summation action; As E – E
0during < ﹣ 10%, show as antagonism.
Table 1, indoor detection fosthiazate, Difenoconazole are evaluated the synergy of cucumber root-knot nematode.
Test shows, fosthiazate, Difenoconazole all show summation action according to the mass ratio of 3:1-10:1 is composite to cucumber root-knot nematode preventive effect, is especially added action effect when fosthiazate, Difenoconazole are composite with the ratio of 5:1 more obvious.
Detected by toxicity, by fosthiazate, Difenoconazole according to the composite discovery of 3:1-10:1 ratio, there is not antagonism in the two, the fosthiazate being mixed with different content Difenoconazole can play better preventive and therapeutic effect to cucumber root-knot nematode, and the single dose of same Difenoconazole mixture to the inhibiting rate of cucumber fusarium axysporum and corresponding concentration is also more consistent.So fosthiazate, Difenoconazole mixture have feasibility, the two is with the ratio best results of 5:1.
Embodiment
The present invention is described by following specific embodiment, but the invention is not restricted to following specific embodiment.In embodiment, each component percentages is mass percentage.
Embodiment one: 6% fosthiazate Difenoconazole granule.
Above-mentioned active ingredient and auxiliary agent are mediated through mixing and water adding, uses pinch-out granulator pinch out and be shaped, afterwards by particle fluid-bed drying, screening, 6% fosthiazate Difenoconazole granule can be obtained.
Embodiment two: test examples.
Adopt embodiment one 6% fosthiazate Difenoconazole granule control cucumber root-knot nematode and seedling stage fusarium wilt, test site is Guangdong Huizhou city, and test period is in August, 2012, selects the field that in soil, nematode population is more, adopts before transplanting and spreads fertilizer over the fields mode.With 20% fosthiazate soluble granule, 500 times of liquid, 24% difenoconazole suspending agent, 1500 times of liquid for contrast medicament, 6% fosthiazate Difenoconazole granule mu carries out test with 3000 grams and processes.Investigate preventive effect respectively at 1d, 3d, 7d, 20d after medicine, after medicine, 3d preventive effect calculates in strict accordance with the computational methods of regulation in National Standard of the People's Republic of China's " pesticide efficacy field trial criterion ".Above medicament 7d post-equalization preventive effect sees the following form.Test shows that 6% fosthiazate Difenoconazole granule has cucumber root-knot nematode, fusarium wilt and well prevents and treats therapeutic action.
Table 2, control cucumber root-knot nematode test of pesticide effectiveness result.
Table 3, control cucumber fusarium axysporum test of pesticide effectiveness result.
Shown by indoor biometrics test and a large amount of outdoor field comparison test, 6% fosthiazate Difenoconazole granule to cucumber root-knot nematode and seedling stage fusarium wilt there is good control efficiency, be that one is worth of widely use pesticide species.
