Abstract
The present invention discloses fipronil composite pesticide which belongs to the technical field of composite pesticide. The fipronil composite pesticide is characterized in that the fipronil composite pesticide comprises 0.5 to 10% of fipronil and 10 to 60% of diazinon, or 0.5 to 10% of fipronil and 10 to 60% of phenthoate. The cotoxicity coefficient of the fipronil composite pesticide can reach 240 to 538. The fipronil composite pesticide has a favorable effect of preventing pests, such as striped rice borer, etc., and the preventing rate reaches 97.8%. The fipronil composite pesticide has the advantages of favorable quick-acting performance, favorable keeping efficiency, little damage to environments and human body, and low operating cost. Compared with fipronil pesticide, the operating cost of the fipronil composite pesticide is reduced by 25% to 50%.
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) to fish, honeybee, with low cost, as pesticide species such as diazinon, phenthoate dimephenthoate cidial, carry out reasonably composite with it, test through series of selection, the tangible composition of selective advance strengthens quick-acting, and reducing pesticide cost is the key point of Firponil compounded pesticide.
Summary of the invention
Based on the problems referred to above, the technical scheme of the Firponil compounded pesticide that insects such as the object of the invention is to provide a kind of poisoning, cost is low, insecticidal spectrum is wide, control striped rice borer are effective.
