Nylar as far back as 1989 by Japanese Sumitomo Chemical Co., Ltd. registers use in public health service, nineteen ninety-five starts to be registered in agricultural and to use in Japan.Application is abroad very general, comprises that the product of the various formulations of numerous foreign corporations such as SUMITOMO CHEMICAL KCC obtains registration at whole world most countries and area.
This product has interior suction transfer activity, low toxicity, and the lasting period is long, to crop safety, and to fish low toxicity, the feature little to eco-environmental impact, but its action effect is also very single, and after large-scale application, resistance risk is also very high.
Summary of the invention
The object of the present invention is to provide a kind of water dispersible granules and application thereof that has beta-cypermethrin and Nylar; said composition active ingredient is beta-cypermethrin and Nylar; wherein the weight ratio of beta-cypermethrin and Nylar is; beta-cypermethrin: Nylar=1:5-1:10; farthest alleviated the problem of current pest resistance to insecticide; thereby reduced the consumption of agricultural chemicals; also alleviated the impact for environment; the trend that meets future society environmental protection, composition of the present invention is received best crop protection effect.
Technical scheme of the present invention is:
A water dispersible granules for beta-cypermethrin and Nylar, active ingredient is beta-cypermethrin and Nylar, wherein the weight ratio of beta-cypermethrin and Nylar is, beta-cypermethrin: Nylar=1:5-1:10.
As preferably, the weight ratio of beta-cypermethrin and Nylar is, beta-cypermethrin: Nylar=1:5-1:7.
The water dispersible granules of beta-cypermethrin of the present invention and Nylar, it consists of following component by weight percentage:
Beta-cypermethrin 5-10%,
Nylar 25-50%,
Dispersant 5-8%;
Anti-hard water agent 1-3%;
Wetting agent 5-6%;
Disintegrant 10-15%;
Filler surplus.
Wherein, described dispersant is: a kind of in polyoxyethylene polyoxypropylene block copolymer, lignin sulfonic acid sodium salt, naphthalene sulfonic acid-formaldehyde condensation product sodium salt.
Described anti-hard water agent is: a kind of in sodium phosphate trimer, EDETATE SODIUM salt, laminated crystal of sodium disilicate.
Described wetting agent is: a kind of in alkylsurfuric acid sodium salt, alkyl naphthalene sulfonic acid sodium salt, alkylaryl polyoxyethylene ether sulfate.
Described disintegrant is: a kind of in anhydrous sodium sulfate, ammonium sulfate, polyvinylpyrrolidone.
Described filler is: a kind of in fine particle calcium carbonate, corn starch, kaolin, bentonite.
Wherein, the total weight percentage of described active ingredient is 40～60%.
The water dispersible granules of beta-cypermethrin of the present invention and Nylar, for preventing and treating the insect of citrus vegetables and ornamental plants, as Bemisia tabaci, scale insect, diamond-back moth, beet armyworm, prodenia litura, pear psyllid, thrips, large trypetid, be particularly useful for preventing and treating citrus fruit fly.
Beneficial effect of the present invention is:
Said composition is composite water dispersible granules composition, compare with single product, the feature with binary composition, strengthened significantly effect, delay the generation of pest resistance to insecticide, and expanded effective active control spectrum, and thering is speed fast, the lasting period is long, consumption is low, eco-friendly feature, the more important thing is, this compounded combination has effectively resisted the problem that pest resistance produces, farthest alleviated the problem of current pest resistance to insecticide, thereby reduced the consumption of agricultural chemicals, also alleviated the impact for environment, met the trend of future society environmental protection.The control efficiency of composition of the present invention is especially good to control citrus fruit fly, is mainly by the result of the synergistic function between each component.
Compound synergic research to composition of the present invention, test adopts the diamond-back moth in field, after raising for test.
Concrete grammar is: adopting commercially available former medicine to carry out composite is needed preparation.Examination worm is the pickles chrysalis of picking up from field, four generations of indoor feeding, select the second instar larvae of growth uniformity, access is put in the culture dish of 10 centimetres of diameters of cabbage leaf (black leaf Chinese cabbage, outermost layer blade), and every ware connects 40, every processing connects three wares, with POTT spray tower, under SOPSI pressure, spray, spray a ware at every turn, 4 milliliters of every ware spraying liquids.General each processing arranges 1-7 concentration gradient.The culture dish of processing is put into 25 ℃, in 12H/l2H illumination box, cultivates, and within 48 hours, checks survival borer population, calculates insect population decline rate.Blank spray equivalent clear water.By method of least squares, calculate virulence equation and lethal concentration of 50 LC50, according to the abundant method of Sun Yun, calculate the toxicity index of medicament and mixed co-toxicity coefficient (CTC value).
The toxicity test result of the different proportion relations of table 1 to diamond-back moth
| Process | LC50（PPM） | Co-toxicity coefficient |
| Beta-cypermethrin 1: Nylar 5 | 0.877 | 557.1 |
| Beta-cypermethrin 1: Nylar 6 | 0.703 | 745.3 |
| Beta-cypermethrin 1: Nylar 7 | 0.62 | 845.5 |
| Beta-cypermethrin 1: Nylar 10 | 0.723 | 637.60 |
| Beta-cypermethrin | 21.04 | ? |
| Nylar | 0.614 | ? |
As can be seen from Table 1, beta-cypermethrin and Nylar composite, has very high synergistic effect, especially beta-cypermethrin: during Nylar=1:5-1:7, synergistic effect is more obvious.
