Description
Technical field
The invention belongs to agricultural chemicals technical fields, and in particular to a kind of agricultural chemical composition and application thereof.
Background technique
Chemical prevention is agriculturally to prevent and control an important means for pest.However, currently used medicament is to certain
The effect of a little pests is still not satisfied enough；Also, since long-time uses insecticide, many pests have been produced to common insecticide
Resistance.For certain pests, especially to the stinkbug class (Stinkbug) of sucking mouth parts, wood louse class (Cryptophagus
Decoratus, plant lousen), aleyrodid class (Whitefly), Phytophthira (Aphid), shell insects (Icerya
Purchasi), for thrips class (Thrips), mite class (acaridn), planthopper (Rice planthopper), routine is utilized
Medicament carries out prevention and control and just becomes increasingly difficult.Therefore, there is an urgent need to develop go out for controlling these pests and providing fungicide
With the new method and drug of herbicide effects.In addition, also continuous currently for requirement of the insecticide on environment and economic aspect
It improves, such as effect wide spectrum, toxicity, selectivity, pesticide residue and advantageous preparation ability etc..In addition, also as may be right
Resistance is led to the problem of in known activity compound, developing new at least has in some or some aspects relative to existing drug
The novel new product for killing sucking pest of advantage is just at a permanent task.

As seen from the above table ,+70% thiophanate-methyl is wettable after sodium pyrosulfite and aerosol-OT salt compound
Property pulvis synergistic effect it is obvious, single dose is significantly better than to the preventive effect of bitter rot or anthracnose of grape, also above 70% methyl sulfur bacterium is used alone
Clever wettable powder.The 70% thiophanate-methyl wettable powder that one third can be reduced in situation similar in preventive effect, from
And alleviate pesticide environmental pollution.
Test example 6：It is tested with 41% glyphosate isopropyl amine salt interworking annual grassy weeds
On annual grassy weeds (such as barnyard grass, herba setariae viridis, amur foxtail, herba eleusines indicae, grasswort, herba digitariae, Chenopodiaceae, herba stellariae mediae, clearvers),
It is handled, is passed through by sprinkling by the dilution of required application concentration with+41% glyphosate isopropyl amine salt of embodiment 1-6 formulation product
After seven days Germicidal efficacies, the weeds death rate indicated in the form of % is determined.100% refers to that the weeds death rate reaches 100%；
0% refers to weeds without death.
As seen from the above table ,+41% glyphosate isopropyl amine salt after sodium pyrosulfite and aerosol-OT salt compound
Synergistic effect is obvious, to annual grassy weeds (such as barnyard grass, herba setariae viridis, amur foxtail, herba eleusines indicae, grasswort, herba digitariae, Chenopodiaceae, herba stellariae mediae, clearvers
Deng) it is significantly better than single dose, also above 41% glyphosate isopropyl amine salt is used alone.Three can be reduced in situation similar in preventive effect
/ mono- 41% glyphosate isopropyl amine salt, to alleviate pesticide environmental pollution.
The present invention is not limited to above-mentioned optional embodiment, anyone can show that other are each under the inspiration of the present invention
The product of kind form.Above-mentioned specific embodiment should not be understood the limitation of pairs of protection scope of the present invention, protection of the invention
Range should be subject to be defined in claims, and specification can be used for interpreting the claims.
