Abstract
An agricultural chemical for preventing and eliminating striped rice borer is prepared from fipronil and fenitrothion or ethion through proportionally mixing.
Description
Technical field
The invention belongs to technical field of compounded pesticide.
Background technology
Fluorine worm nitrile agricultural chemicals used on China paddy rice and obtains interim registration (5% colloidal suspending agent) in 1994, and registration number is LS94007.Be widely used in the control of rice grub and migratory locusts in recent years,, good control efficiency arranged as insects such as rice goitre line, rice thrips, striped rice borer, rice fulgorid, oryza chinensis to rice grub.But the control efficiency to paddy stem borer, rice leaf roller is undesirable, and is bad to the pink rice borer control efficiency that takes place on the paddy rice, and therefore, in the paddy rice producing region of using fluorine worm nitrile 3-4, the population ratio of pink rice borer rises very fast.Higher to the toxicity of fishes and shrimps in addition, in the network of rivers, the lake region uses and also can be subjected to certain restriction.Simultaneously, the quick-acting of fluorine worm nitrile agricultural chemicals is poor slightly, agricultural chemicals price higher (7～9 yuan every mu), and this also is to limit this medicine in one of widely used factor of China.
Fluorine worm nitrile is this to have a moderate toxicity in order to make, and insecticidal spectrum is wide and can adapt to China rice grub to the agricultural chemicals of advantages such as pest controling effects such as striped rice borer are good and prevent and treat, and can play better effect in the rice disease and pest integrated control.Adopt the big or middle low toxicity of the present production scale of China (comprising), with low cost to fish, honeybee, carry out reasonably composite with it as agricultural chemicals such as sumithion, ethions, test through series of selection, the tangible composition of selective advance, strengthen quick-acting, reducing pesticide cost is the key point of Firponil compounded pesticide.
Summary of the invention
Based on the problems referred to above, the object of the invention is to provide a kind of poisoning, cost is low, insecticidal spectrum is wide, insect such as control striped rice borer etc. is effective and quick-acting, the lasting effect technical scheme of Firponil compounded pesticide preferably.
Described a kind of Firponil compounded pesticide is characterized in that: contain fluorine worm nitrile 0.5-10%, sumithion 10-60%.
Described a kind of Firponil compounded pesticide is characterized in that: the content of fluorine worm nitrile is 1-5%, and the content of sumithion is 20-40%.
