Abstract
The invention discloses a bamboo vinegar contained pesticide aqueous emulsion which comprises the following components by weight: 1 to 20 percents of pyrethroid, 5 to 10 percents of organic solvent, 2 to 10 percents of emulsifier, 1 to 3 percents of dispersant, 1 to 5 percents of anti-freeze agent, 0.1 to 3 percents of thickening agent, 30 to 60 percents of bamboo vinegar and balance water. The pyrethroid is shown as a first equation, wherein R1 is a group as follows: Cl2 = CH-, (CH3)2C = CH-, Br2C = CH- or CF3ClC = CH-. The invention also provides a method for preparing the bamboo vinegar contained pesticide aqueous emulsion applied to the prevention of agricultural insects. The bamboo vinegar contained pesticide aqueous emulsion comprises the pyrethroid and the bamboo vinegar and accords with the quality requirements of agricultural preparations without on-site preparation, and moreover, the bamboo vinegar can improve the insecticidal action of the pyrethroid. Compared with the prior agricultural composition only comprising the pyrethroid, the invention achieves the same insecticidal action, decreases the effective ingredient consumption of the pyrethroid by about 50 percents and is non-toxic and pollution-free.
Description
Technical field
The present invention relates to a kind of bamboo vinegar insecticide aqueous emulsion and preparation method thereof, this kind of containing contains application, this kind that bamboo vinegar insecticide aqueous emulsion is used to prevent and treat the insect of cotton, vegetables, fruit tree, tobacco and contains the application that bamboo vinegar insecticide aqueous emulsion is used to prevent and treat cotton bollworm, pink bollworm, cotten aphid, cabbage caterpillar, diamond-back moth, aphid, ceroplastes rubens, leaf miner, oriental tobacco budworm.
Background technology
Along with the raising of agricultural modernization level, modern agricultural chemicals development faces the immense pressure of food, ecology and Environmental security.At first, food security has become global problem, receives the national governments and the people's common concern, and residue of pesticide are the key factors that influence food security, and the usage amount that reduces chemical pesticide becomes common recognition.Secondly, a large amount of organic solvents that use are serious day by day to the influence of environment in the formulations such as missible oil, and developed country is to an organic solvent restriction increasingly stringent, and the low-pollution water base property formulations of pesticide become the leading formulation of agricultural chemicals development.The 3rd, the pest pesticide resistance strengthens day by day, and the pesticide combination that exploitation has synergistic effect receives extensive attention, also is one of important measures of answering the antagonism pest.
Bamboo vinegar is an accessory substance of firing bamboo charcoal, and moisture can reach more than 90%, and contains number of chemical compositions such as acetic acid.Research shows that bamboo vinegar has effects such as sterilization, infiltration, and agricultural chemicals is had synergistic effect, can effectively reduce the chemical pesticide consumption.Pyrethroid insectide is one type of bionic pesticide, has characteristics such as efficient, low toxicity, low-residual, on producing, has critical role, and its output accounts for 20% of insecticide total amount, and usable floor area reaches 25% of total amount.
Though discovery bamboo vinegar and cypermethrin are used with and are had synergistic effect on producing; Yet bamboo vinegar is used for Synergistic fertilizer and carries out the field when using, and can only carry out scene and prepare; That is join existing usefulness at present; Because bamboo vinegar and agricultural chemicals carry out composite after, the existence that each effective ingredient can not be stable causes difficulty to practical application.Therefore, research and development pyrethroid bamboo vinegar aqueous emulsion has important practical significance, and development prospect is wide.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bamboo vinegar insecticide aqueous emulsion that contains, its good disinsection effect, and consumption is few, good stability.
In order to solve above technical problem, the present invention provides following technical scheme:
A kind of bamboo vinegar insecticide aqueous emulsion that contains comprises following component:
Pyrethroid 1～20%
Organic solvent 5～10%
Emulsifier 2～10%
Dispersant 1～3%
Antifreeze 1～5%
Thickener 0.1～3%
Bamboo vinegar 30～60%
Water surplus;
Each component is all in weight portion, and said pyrethroid is suc as formula shown in (I), wherein, and R
