Abstract
The invention relates to a rain-wash-resistant chlorothalonil suspension agent and a preparation method thereof. The rain-wash-resistant chlorothalonil suspension agent comprises the following components according to weight percentage: 40-60% of chlorothalonil, 1-3% of wetting agent, 2-5% of dispersing agent, 1-5% of potentiating agent, 0.1-0.5% of thickening agent, 0.1-0.5% of preservative, 2-10% of anti-freezing agent, 0.1-0.5% of suspending agent, 0.1-0.5% of defoaming agent, and the balance of water. The preparation method of the rain-wash-resistant chlorothalonil suspension agent comprises the process steps of smashing, mixing and the like. According to the invention, permeability and adhesion of the chlorothalonil on the surface of a plant body are increased; playing of the pesticide effect is enhanced; simultaneously, loss of pesticides caused by rain wash is reduced; and the efficacy period is beneficial to being prolonged.
Description
Technical field
The present invention relates to the pesticide technology converted products, be specifically related to tpn suspending agent of a kind of resistance of rainwater washing against and preparation method thereof.
Background technology
Tpn is the protective fungicide of a kind of low toxicity, wide spectrum; characteristics with non-internal-absorting; the mechanism of action be can with the fungal cell in glyceraldehyde 3-phosphate dehydrogenase have an effect; tie mutually entirely with the protein that contains cysteine in this enzyme; thereby destroy this enzymic activity, fungal cell's metabolism is damaged and loses one's life power.In actual use, because condition effect such as wind, rainfall, dew, Exposures to Sunlight, tpn descends at the tackness of plant surface, particularly will obviously reduce drug effect as rainfall after the dispenser, shortens the drug effect phase.
At present in the main formulation of tpn, pulvis, wetting powder, finish and fumicants often exist dust from flying, contaminated environment, the petrochemical industry wasting of resources and the limited defective of the scope of application, increased application risk and the cost of tpn, become to produce and go up urgent problem.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of fineness that can improve tpn, suspensibility are provided and at the tackness of plant corpus, have prolonged the drug effect phase, improve tpn suspending agent and preparation method thereof of the resistance of rainwater washing against of sterilization and protective effect.
Purpose of the present invention can be achieved through the following technical solutions:
