Embodiment 1

[0036] Embodiment 1, the preparation of mango tree spray aid

[0037] The inventors of the present invention have screened out polyoxyethylene-20 sorbitan monooleate and polyethylene glycol monolaurate from a large number of existing fatty acid esters as the active ingredients of the mango tree spray aid , be equipped with adjuvant (as wetting agent, defoamer, preservative and water) again, have made can significantly reduce the contact angle mango tree spray adjuvant (mango tree of the present invention is used for spraying) Auxiliary).

[0038] 1, the mango tree of the present invention uses spray auxiliary agent

[0039]The mango tree spray aid of the present invention is named as the double fatty acid ester mango tree spray aid, which consists of active components and auxiliary materials, and the mass ratio of active ingredients and auxiliary materials is 3:7. The active ingredient is composed of polyoxyethylene-20 sorbitan monooleate and polyethylene glycol monolaurate,...

Embodiment 2

[0070] Embodiment 2, the mango tree of the present invention uses a spray adjuvant—the double fatty acid ester mango tree uses a spray adjuvant to improve the drug effect of insecticides on mangoes

[0071] A field experiment was conducted in a mango orchard in Yacheng Town, Sanya City, Hainan Province. A total of 12 mango trees were selected, all of which were more than 10 years old. The test consisted of 4 normal concentration groups without spray adjuvant (recommended concentration), normal concentration group with aerosol adjuvants (N13+ recommended concentration), 2 times the normal concentration group without aerosol adjuvants (2 times the recommended concentration) and a blank group For each treatment, 3 mango trees were treated, and these 4 treatment groups were operated in the same way except that the sprayed medicinal liquid was different. Do not use spray adjuvant normal concentration group on August 3, every plant sprays the 400 times dilution of 60g / L ethyl spino...

Embodiment 3

[0077]Embodiment 3, the mango tree of the present invention uses a spray adjuvant—the double fatty acid ester mango tree uses a spray adjuvant to improve the drug effect of insecticides on mangoes

[0078] Test site: Field test was carried out in the mango orchard in Yacheng Town, Sanya City, Hainan Province.

[0079] Experimental fruit trees: A total of 15 mango trees were selected, all of which were more than 10 years old.

[0080] The pesticides used are: emamectin benzoate (5% microemulsion), the spray assistant for mango trees of the present invention.

[0081] Test method: There are 5 treatments in the test, each with 3 mango trees, and each treatment group is: normal concentration group, 15% less pesticide + N13 group, 25% less pesticide + N13 group, 35% less pesticide + N13 group group and minus 50% pesticide+N13 group. Each of the 3 mango trees was treated, and the 5 treatment groups were operated the same except for the sprayed liquid medicine. The drug solution s...

Abstract

The invention discloses a spray additive for mango trees and application of the spray additive. The spray additive for mango trees provided by the invention is composed of an active component and auxiliary materials, wherein the active component is composed of polyoxyethylene sorbitan monooleate and polyethylene glycol monolaurate. The active component of the spray additive for mango trees is a fatty acid lipid surfactant, so that the surface tension of water and liquid medicine can be reduced, the contact angle between liquid medicine fog drops and leaf surfaces can be reduced, and maximum coverage is achieved; therefore, the functions of expansion, attachment and wetting of pesticide spraying liquid drops on plant leaves can be improved, pesticide can be more evenly distributed on the mango leaves, the pesticide effect of the pesticide is improved, meanwhile, the use amount of the pesticide is reduced, and environmental pollution is reduced. The spray additive for mango trees is suitable for various spray pesticides for mango trees, including insecticides, bactericides, herbicides, plant growth regulators, foliar fertilizers and the like.

Description

technical field [0001] The invention relates to a spray auxiliary for mango trees in the field of agricultural plant protection and its application. Background technique [0002] Pesticide adjuvants are the general term for various auxiliary materials used in the processing and application of pesticide formulations. Each pesticide adjuvant has a specific function: some can dilute the original drug; some can help the original drug to disperse evenly in the preparation; some can prevent the droplets from agglomerating and growing; some can increase the wetting of the particles Sex, adhesion or permeability; some can prevent the decomposition of active ingredients; some can increase the safety of application. In short, pesticide adjuvants are used to improve the physical or chemical properties of pesticides, to maximize the efficacy of pesticides or to help safe pesticide application. [0003] Spray adjuvant refers to the general term for adjuvants used in spray application. ...
