Abstract
The invention relates to a water-based pesticide synergist, comprising the following components based on weight percentage: 4-10 of ammonium nitrate, 3-10 of ammonium phosphate, 6-8 of 2-methoxyethanol, 5-8 of butylglycol, 20-30 of emulsifier and 34-59 of water. The ammonium nitrate and the ammonium phosphate are ideal basic fertilizer for mixed fertilizer production and are suitable for various crops and soil, which can directly promote crop growth. OP-7 in the emulsifier is a lipophilic surfactant which is more hydrophilic and lipophilic compared with the conventional cationic surfactant and can reduce the critical micelle concentration and improve the surface activity in an order of magnitude, and is also provided with excellent properties at very low concentrations; besides, the OP-7 in the emulsifier is miscible with the amphoteric surfactant and anionic surfactant selected in the invention, without precipitation; therefore, the water-based pesticide synergist can be used in water-based or alcohol-based pesticide synergism as well as EC-based synergism.
Description
Technical field
The invention belongs to insecticides adjuvant, particularly relate to a kind of water-base pesticides potentiating agent.
Background technology
Pesticide synergistic agent is for reducing the agricultural chemicals usage amount, reduce residue of pesticide, having outstanding effect killing the effect that makes increasing crop yield under the condition of damage by disease and insect.
In the known technology, selected to make from aspects such as wetting, adhesion, infiltrations the surfactant of pesticide synergistic in the technical scheme of part pesticide synergistic agent, also replenished the necessary material of plant growth, these materials can directly promote the composition of plant growth." a kind of pesticide synergistic agent and composition pesticide thereof " like Chinese patent 99105949.2.Above-mentioned pesticide synergistic agent is humic acid and salt thereof, is mixed mutually by the cosolvent of the water of the agricultural chemicals of the synergist of 3-10% and 20-50%, 35-60% and 10-14% and emulsifier in its aqua to constitute.
Summary of the invention
The purpose of this invention is to provide the significant water-base pesticides potentiating agent of a kind of synergy.
Water-base pesticides potentiating agent of the present invention is made up of following components in weight percentage:
Ammonium nitrate 4-10, ammonium phosphate 3-10, ethylene glycol ethyl ether 6-8, butyl glycol ether 5-8, emulsifier 20-30, water 34-59.
Described emulsifier is mixed by the two 16～octadecyl ammonium of non-ionic surface active agent OP-7, amphoteric surfactant betain and anion surfactant chlorination dimethyl and forms, and weight ratio was followed successively by 4: 2: 1.
In the composition component of the present invention, ammonium nitrate and ammonium phosphate are the desirable base fertilizers of producing mixed fertilizer, are suitable for various crops and soil application, have the effect that can directly promote plant growth.OP-7 is a kind of lipophilic surfactant in the emulsifier; Compare with conventional cationic surfactant, it is hydrophilic, lipophilic group is more, can become the order of magnitude to reduce critical micelle concentration; Can become the order of magnitude to improve surface-active; Under extremely low concentration, promptly have excellent performance, and amphoteric surfactant, the anion surfactant selected with the present invention are miscible and do not precipitate, therefore; Water-base pesticides potentiating agent of the present invention not only can be applied to the synergy of water-based or alcohol property agricultural chemicals, also can be applied to the synergy of missible oil property agricultural chemicals.
The effect of this water-base pesticides potentiating agent can be explained by following contrast experiment's result.
The effect comparison experimental result that the insecticidal effect of example 1:1.1% green sea natural botanical insecticide and 1.1% green sea natural botanical insecticide and this water-base pesticides potentiating agent mix by 1: 2 weight ratio is seen table 1:
Table 1
| The insect name | Extension rate | (1) killing rate % | (2) killing rate % |
| Aphid | 800 | 85 | 98 |
