Spiral shell worm ethyl ester has unique function Characteristics, is one of modern pesticides so far with two-way Uptake and translocation performance.This compound upwards can move down in whole plant corpus, arrives at blade face and bark, thus control is as on romaine lettuce and Chinese cabbage internal lobe, and the corticole insect of fruit.The interior absorption of this uniqueness can protect newborn stem, leaf and root, prevents ovum and the larval growth of insect.Its another feature is that the lasting period is long, can provide the effective control reaching 8 weeks.
But its action effect is also very single, 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 the application thereof that contain spiral shell worm ethyl ester; said composition active ingredient is beta-cypermethrin and spiral shell worm ethyl ester; wherein the weight ratio of beta-cypermethrin and spiral shell worm ethyl ester is; beta-cypermethrin: spiral shell worm ethyl ester=1:5-1:10; farthest alleviate the problem of current pest resistance to insecticide; thus decrease the consumption of agricultural chemicals; also the impact for environment is alleviated; meet the trend of future society environmental protection, composition of the present invention receives best crop protection effect.
Technical scheme of the present invention is:
A water dispersible granules containing spiral shell worm ethyl ester, active ingredient is beta-cypermethrin and spiral shell worm ethyl ester, and wherein the weight ratio of beta-cypermethrin and spiral shell worm ethyl ester is, beta-cypermethrin: spiral shell worm ethyl ester=1:1-1:10.
As preferably, the weight ratio of beta-cypermethrin and spiral shell worm ethyl ester is, beta-cypermethrin: spiral shell worm ethyl ester=1:2-1:4.
Water dispersible granules containing spiral shell worm ethyl ester of the present invention, it consists of following component by weight percentage:
Beta-cypermethrin 1-50%,
Spiral shell worm ethyl ester 1-50%,
Agriculture breast 400# 4-7%;
Laminated crystal of sodium disilicate 1-5%;
Alkylphenol polyoxyethylene 5-10%;
Sodium carboxymethyl starch 2-20%;
Kaolin surplus.
As preferably, the water dispersible granules containing spiral shell worm ethyl ester of the present invention, it consists of following component by weight percentage:
Beta-cypermethrin 5-10%,
Spiral shell worm ethyl ester 10-40%,
Agriculture breast 400# 4-7%;
Laminated crystal of sodium disilicate 1-5%;
Alkylphenol polyoxyethylene 5-10%;
Sodium carboxymethyl starch 2-20%;
Kaolin surplus.
Wherein, the total weight percentage of described active ingredient is 30 ~ 60%.
Water dispersible granules containing spiral shell worm ethyl ester of the present invention, for preventing and treating mealybug, two spotted spider mite, mandarin tree scale insect, is particularly useful for control mandarin tree scale insect.
Beneficial effect of the present invention is:
Said composition is compound water dispersible granule composition, compared with single product, there is the feature of binary composition, significantly enhance effect, delay the generation of pest resistance to insecticide, and expand effective active control spectrum, have 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 alleviate the problem of current pest resistance to insecticide, thus decrease the consumption of agricultural chemicals, also alleviate the impact for environment, meet the trend of future society environmental protection.The control efficiency of composition of the present invention is especially good to control mandarin tree scale insect, mainly by the result of the synergistic function between each component.
Study the compound synergic of composition of the present invention, test adopts the mandarin tree scale insect in field.
Toxicity index and the mixed co-toxicity coefficient (CTC value) of medicament is calculated according to the abundant method of Sun Yun.
Table 1 different ratio relation is to the toxicity test result of mandarin tree scale insect
| Process | Co-toxicity coefficient |
| Beta-cypermethrin 1: spiral shell worm ethyl ester 1 | 213.6 |
| Beta-cypermethrin 1: spiral shell worm ethyl ester 2 | 298.5 |
| Beta-cypermethrin 1: spiral shell worm ethyl ester 4 | 290.7 |
| Beta-cypermethrin 1: spiral shell worm ethyl ester 5 | 202.7 |
| Beta-cypermethrin 1: spiral shell worm ethyl ester 10 | 120.5 |
| Beta-cypermethrin | |
| Spiral shell worm ethyl ester |
As can be seen from Table 1, beta-cypermethrin and spiral shell worm ethyl ester composite, has very high synergistic effect, especially beta-cypermethrin: during spiral shell worm ethyl ester=1:2-1:4, synergistic effect is more obvious.
