Description
Technical field
The invention belongs to chemical pesticide applied technical fields, and in particular to a kind of active ingredient includes Prochloraz and spiral shell worm
The seed treatment compositions of ethyl ester prevent bakanae disease and rice thrips for rice seedling seedling stage.
Background technology
Bakanae disease of rice and rice thrips are the rice often property sent out, cause harm serious seeding stage pest and disease damage, bakanae disease of rice and rice
Thrips occurs, once not preventing in time, to be easy to cause Severe Reduction.Bakanae disease of rice is also known as excessive growth disease, and each rice region of China is equal
There is generation, a kind of disease of initiation is infected by Fusorium moniliforme Sheldon, infected seed and sick straw, which are that bakanae disease of rice is pathogenetic, just invades
Dye source, paddy of being fallen ill after planting often do not germinate or cannot be unearthed；Falling ill, seedling is thinner and taller than strong seedling, and blade leaf sheath is elongated, and leaf color is light
Huang, root system development is bad, and part sick seedling is dead before transplanting.Rice thrips growth cycle is short, and generation is more, generation overlap,
Broken blade face is filed with mouthpart into, nymph and sucks juice, into fine yellowish-white color spot, the inside convolution in blade tip both sides, gradually and full leaf crispatura it is withered
Yellow, wilting, especially rice shoot is aggrieved even more serious, often withered in flakes, and shape is as burnt.
Prochloraz (prochloraz) is imidazoles broad-spectrum germicide, is caused by inhibiting the biosynthesis of sterol
Effect, although not having systemic action, it has certain conductive performance, for works a variety of caused by sac fungus and Fungi Imperfecti
Object disease has special efficacy.
Spiral shell worm ethyl ester (spirotetramat) is a kind of novel tetronic acid insecticides, and insecticidal spectrum is wide, and the lasting period is long.It
It is that dead larvae is led to by the fatty biosynthesis of interference insect, reduces the fertility of adult.Due to its unique effect
Mechanism can effectively prevent the pest that resistance is generated to existing insecticide, at the same time as nicotinic insecticide resistance management
Important kind.
For rice seedling seedling stage bakanae disease and rice thrips prevention problem, the present inventor is furtherd investigate, by largely trying
It issues after examination and approval now, rice seedling seedling stage bakanae disease and rice thrips can effectively be prevented by carrying out rice paddy seed processing using Prochloraz, spiral shell worm ethyl ester
Cause harm, Prochloraz and spiral shell worm ethyl ester combination have notable synergistic effect, improve using effect, expand prevention spectrum.
