Problems solved by technology

[0004] The agricultural spray auxiliaries currently on the market are mainly surfactants, which are mainly divided into four categories: nonionic surfactants, anionic surfactants, cationic surfactants and amphoteric surfactants. However, the use of a large number of surfactants , although it can improve the efficacy of pesticides, but because nonylphenol is the main raw material for surfactant processing, it is a chemical auxiliary product that is restricted in the world, and has certain toxicity. In an environment that is not conducive to microbial degradation, it will There are certain carcinogenicity, teratogenicity, mutagenicity and sensitization, which pose a great threat to people's health

Embodiment 1

[0020] An agricultural spraying auxiliary agent, comprising the following components in weight ratio: limonene 15%, calcium dodecylbenzene sulfonate 5%, and the balance is mineral oil. The mineral oil is selected from the mineral oil sourced from naphthenic base oil with a carbon chain distribution of C21-C25 with a content of more than 70wt.%.

Embodiment 2

[0022] An agricultural spraying aid, comprising the following components in weight ratio: limonene 10%, fatty alcohol polyoxyethylene ether 10%, and the balance is mineral oil. The mineral oil is selected from the mineral oil sourced from paraffin base oil with a carbon chain distribution of C21-C25 with a content of more than 70wt.%.

Embodiment 3

[0024] An agricultural spraying aid, comprising the following components in weight ratio: limonene 12%, Span 80 emulsifier 8%, and the balance is mineral oil. The mineral oil is selected from the mineral oil sourced from aromatic base oil with a carbon chain distribution of C21-C25 with a content of more than 70wt.%.

Abstract

The invention discloses an agricultural spray additive including, by weight, 5-15% of limonene, 5-10% of a surfactant and the balance being mineral oil. Through physical synergistic effect of the mineral oil and with effective combination of the limonene, wetting, adhesion and permeation effects of a liquid reagent are enhanced, evaporation speed is also reduced; thereby achieving synergistic effect on present pesticides, bactericides and herbicides.

Description

Technical field [0001] The invention relates to the technical field of pesticides, especially agricultural spraying aids. Background technique [0002] Pesticide adjuvants are used with pesticides to reduce the amount of pesticides used and improve the efficacy of pesticides by improving the physical or chemical properties of the pesticides; in general, pesticide adjuvants have no biological activity, but they are indispensable in formulations or application Of additives. Each pesticide adjuvant has a specific function: some can dilute the original drug; some can help the original drug be evenly dispersed in the preparation; some can prevent the droplets from agglomerating and becoming larger; 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 and so on. [0003] In the spray application technology, there is a widespread problem of low effective utiliza...
