Description
Technical Field
The invention relates to the technical field of pesticides, in particular to a composition for preventing and controlling taro field aphids.
Background
Aphis gossypii is a hemiptera dental, and is mainly harmful to cotton, vegetables, flowers, fruit trees and the like, and the vegetables mainly comprise cucurbitaceae, cruciferae, solanaceae, leguminosae, umbelliferae, liliaceae, amaranthaceae, asparagus cochinchinensis, araceae and the like, and especially the melons and the vegetables are serious.
Taro is a perennial herb of the genus taro of the family Araceae, and is widely cultivated throughout the world. Taro is one of the hosts of Aphis gossypii, and is harmful to the Aphis gossypii and if the buds are pricked on the back of the leaves and tender stems of the taro. At the early stage of damage, the leaves lose green and turn yellow, shrink and malformation, tender leaves curl and are not unfolded, and when serious, the leaves can be withered, dead, plant dysplasia and growth retardation can be caused, so that yield reduction is caused. In addition, the honeydew and the slough of the cotton aphid excrement are extremely easy to develop mould, so that the photosynthesis of crops is weakened.
At present, the control of the taro field aphids takes spraying chemical agents as the main component, and the chemical agents have the advantages of quick effect and good control effect, but the chemical agents have the defects of drug resistance, pesticide residues and environmental pollution, and especially the negative effects of the chemical agents are more prominent under the condition of long-term application of single chemical agents. Compounding different pesticide varieties is a common method for developing novel medicaments. Three types of effects can be shown after the pesticide variety is compounded: antagonism, additive and synergistic. The synergistic effect of the small scale can improve the control effect on the target, effectively delay the generation of drug resistance, and be beneficial to reducing pesticide residues and environmental pollution.
The hydroprene is a novel pesticide under the Pasteur flag, and plays a role by interfering with the regulation and control of an insect vanillic acid transient receptor channel complex, so that feeding and other behaviors of insects are interfered, and finally the insects are starved and dead, so that piercing-sucking pests and sucking pests can be effectively prevented and controlled, and the pesticide is environment-friendly and suitable for pest resistance management and comprehensive treatment of pests. Application number CN202010876866.4 discloses an insecticidal composition of spiromesifen and hydroprene and application thereof, and specifically discloses an insecticidal composition of spiromesifen and hydroprene, wherein the mass ratio of spiromesifen to hydroprene is 10:1-1:5, the pesticide composition has synergistic effect on controlling crop bemisia tabaci and aphids.
Metaflumizone belongs to semicarbazone pesticides, and is mainly used for killing pests through stomach toxicity when the pests eat and enter the body, so that the metaflumizone has small contact killing effect and no systemic effect, and has good control effect on target pests in all ages. The pests enter the bodies after feeding, and the sodium ion channels on the axon membranes of the neurons of the pests are blocked, so that the sodium ions cannot pass through the axon membranes, and further, nerve impulses are inhibited to enable the bodies to relax excessively, paralysis is achieved, and the pests stop feeding after a few hours and die within 1-3 days.
The bifenazate is a bifenazate acaricide for selective foliar spray. The mechanism of action of bifenazate is a unique effect on a gamma-aminobutyric acid receptor of the central nervous system of mites. Application number CN201410811746.0 discloses a suspension agent containing pymetrozine and bifenazate, and specifically discloses a suspension agent containing pymetrozine and bifenazate with a mass ratio of 15:1-1:15, the insecticidal composition has synergistic effect on controlling pests such as cabbage aphids, tetranychus urticae and tetranychus truncatus.
The inventor finds that the synergistic effect is shown on preventing and controlling the taro Tian Mian aphid when the hydroprene is compounded with metaflumizone or bifenazate through indoor experiments. At present, no related report exists.
Disclosure of Invention
The invention aims to provide a composition for preventing and controlling taro field aphids, which can improve the prevention and control effect on targets, effectively delay the generation of drug resistance, and is beneficial to reducing pesticide residues and reducing environmental pollution.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the effective component of the composition for preventing and controlling the taro field aphids is compounded by the hydroprene of the double propineb and metaflumizone or bifenazate, and the mass ratio of the hydroprene of the double propineb to the metaflumizone or the bifenazate is 1-150:150-1.
Preferably, the mass ratio of the hydroprene of the two propisochlor to the metaflumizone is 1-50:19-1.
Preferably, the mass ratio of the hydroprene to the bifenazate is 1-25:80-1.
Preferably, the mass ratio of the hydroprene to the bifenazate is 1:7.5.
compared with the prior art, the invention has the following beneficial effects:
(1) When the hydroprene and metaflumizone or bifenazate in the composition are compounded, the composition has a synergistic effect on preventing and controlling the taro Tian Mian aphid within a certain mass ratio range, can improve the prevention and control effect on the taro Tian Mian aphid, is beneficial to reducing the use amount of active ingredients, and reduces pesticide residues, prevention and control cost and environmental pollution.
(2) The pesticide mechanism of the hydroprene and metaflumizone or bifenazate in the composition is different, and when the composition is compounded for use, taro Tian Mian aphids can be killed from different action sites, so that the generation of drug resistance of pests is slowed down, and the service life of the pesticide can be prolonged.
Detailed Description
The invention will be better understood from the following examples, which are described only for illustration of the invention and should not be construed as limiting the invention as detailed in the claims.
Examples: indoor biological activity test of diprocyclfen compound
1. Test object: cotton aphids collected from the taro field of Guangxi Lipu city are fed with fresh and clean taro leaves in a laboratory, and wing-free adult aphids with basically consistent size and vitality are selected as test objects.
2. Test agent

96% metaflumizone (Beijing Bonong chemical technology Co., ltd.)
97% Bifenazate (Jiangsu province pesticide research institute Co., ltd.)
The raw materials are dissolved by dimethyl sulfoxide to prepare a single-dose mother solution, then the single-dose mother solution is diluted by 0.1% Tween-80 aqueous solution, a plurality of groups of proportions are arranged, and each single dose and each group of proportion mixture are provided with 6 gradient mass concentrations according to an equal ratio method for standby.
3. Test method
The leaf dipping method is adopted. Fresh and clean taro She Caijian is formed into a round shape with the size of a culture dish, the cut taro leaves are clamped by forceps and immersed in a solution of a medicament to be detected, and the taro leaves are taken out after 10s and dried in the culture dish with soaked filter paper. And (3) inoculating 25 test objects on the blades in each culture dish, wrapping the whole culture dish with a preservative film, sealing the culture dish with a sealing film, and finally pricking small holes on the preservative film with an insect needle to ensure the normal life activities of the test objects. Placing the culture dish at the temperature (25+/-1) DEG C and the humidity of 50-60% and the photoperiod of 16L: feeding observations at 8D were repeated 4 times for each treatment, and treatments containing only dimethyl sulfoxide were set as blank.
