Abstract
The present invention relates to complex pesticide for rice field and its preparation process. The complex pesticide is prepared by mixing monosultap 20-60 wt%, profenophos 5-25 wt% and assistant the rest. The assistants is the mixture of light calcium carbonate, dispersant and white carbon black. The complex pesticide is prepared through mixing profenophos and white carbon black to make profenophos adsorbed by white carbon black, crushing in airflow crusher into powder, and mixing the powder with monosultap powder, light calcium carbonate and dispersant. The complex pesticide has obviously pesticidal effect.
Description
Technical field
The present invention relates to a kind of crops pesticide, compounded pesticides that particularly a kind of paddy field is used and preparation method thereof.
Background technology
Existing single agent desinsection list to the rice leaf roller control efficiency between 55.6%-75%, rate of leaf protection 55.7-74.4%.And single agent Profenofos is 40.2-55.6% to the rice leaf folder control efficiency, rate of leaf protection 44.6-60.5%.Their control efficiency and rate of leaf protection are low, and use cost is also higher.Equally, they also exist control efficiency and the low problem of rate of leaf protection to rice grub striped rice borer, paddy stem borer.
Summary of the invention
Purpose of the present invention is exactly that it is low to propose a kind of use cost, compounded pesticides that control efficiency and rate of leaf protection are high and preparation method thereof in order to address the above problem.
Technical solution of the present invention:
Compounded pesticides of the present invention is mixed and made into by desinsection list, Profenofos and auxiliary agent, and the percentage by weight of its each composition is:
Desinsection list 20-60%
Profenofos 5-25%
The auxiliary agent surplus.
Wherein, auxiliary agent is the mixture of precipitated calcium carbonate, dispersant, white carbon.The percentage by weight of three kinds of materials is in the auxiliary agent:
Dispersant 1-5%
White carbon 5-32%
The precipitated calcium carbonate surplus.
A kind of preparation method of compounded pesticides, it is characterized in that earlier Profenofos missible oil is mixed with white carbon in the auxiliary agent, their proportioning is, Profenofos missible oil: white carbon=1: 0.3-1, Profenofos is adsorbed on the white carbon, pulverize through airslide disintegrating mill again and become the Profenofos pulvis, then dispersant, precipitated calcium carbonate in this Profenofos pulvis and desinsection list pulvis and the auxiliary agent are mixed together to stir and promptly get compounded pesticides of the present invention.
Use compounded pesticides of the present invention not only can save peasant's use cost, and control efficiency and rate of leaf protection obviously improve, composite back rice leaf folder control efficiency can reach 82-97%, and rate of leaf protection reaches 84.4-99.4%.Simultaneously, control efficiency and the rate of leaf protection of rice grub striped rice borer, paddy stem borer are imitated also raising greatly, effect is very good.
Embodiment
Compounded pesticides of the present invention is mixed to stir by desinsection list, the former medicine of Profenofos and auxiliary agent to be made, and the percentage by weight of its each composition is:
Desinsection list 20-60%
The former medicine 5-25% of Profenofos
The auxiliary agent surplus.
Wherein, auxiliary agent is the mixture of precipitated calcium carbonate, dispersant, white carbon.The percentage by weight of three kinds of materials is in the auxiliary agent:
Dispersant 1-5%
White carbon 5-32%
The precipitated calcium carbonate surplus.
Preparation method of the present invention is, earlier Profenofos missible oil is mixed with white carbon in the auxiliary agent, their proportioning is, Profenofos missible oil: white carbon=1: 0.3-1, its best proportioning is: Profenofos missible oil: white carbon=1: 0.5-1, Profenofos is adsorbed on the white carbon, through airslide disintegrating mill pulverizing becoming Profenofos pulvis, the order number is mixed together dispersant, precipitated calcium carbonate in this Profenofos pulvis and desinsection list pulvis and the auxiliary agent to stir then and promptly gets compounded pesticides of the present invention generally more than 200 orders.
Embodiment (is example to prepare 10 kilograms of compounded pesticides):
Earlier 1.5 kilograms the Profenofos missible oil white carbon with 0.75 kilogram is mixed, Profenofos is adsorbed on the white carbon, obtain about 2.25 kilograms Profenofos pulvis through the airslide disintegrating mill pulverizing, the order number is 200 orders.Then the dispersant N of this Profenofos pulvis and 3 kilograms of desinsection list pulvis (content is 90%) and 0.2 kilogram, 4.55 kilograms precipitated calcium carbonate are mixed together to stir and promptly get compounded pesticides of the present invention.
Embodiments of the invention are non-limiting example, and the proportioning of its each composition can be selected arbitrarily by the afore mentioned rules scope, all can make compounded pesticides of the present invention.
Claims (4)
