Description
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, be specially a kind of water dispersible granules and the application that prevent and treat white-backed planthopper.
Background technology
fluorobenzene urea
Fluorobenzene urea is a kind of phenyl formoxyl ureas novel pesticide, has stomach toxicity, action of contace poison, without systemic action, belongs to low toxic pesticide, to fish and birds low toxicity, nontoxic to honeybee, to crop safety.The fluorobenzene urea mechanism of action mainly suppresses chitin synthesis, after polypide contact, destroys the formation of insect chitin.
macro tetrolide
Be the antibiotic with macrolide structure produced by the mutation of streptomyces griseus Liuyang, for low toxicity, low-residual, can prevent and treat the broad spectrum acaricides of the multiple mite class of various crop, control efficiency is good.Have good action of contace poison to the tetranychid of various crop, without interior absorption, medicament has lipophilicity, if having efficiently one-tenth mite, does not kill and wound Predatory Mites, and evil mite not easily produces resistance, kills mite spectrum comparatively extensively, all effective to tetranychid, goitre mite.With some organic phosphors or carbamate pesticide composite, have significant synergistic effect.To the action of contace poison of evil mite, 7 ~ 14 days lasting periods.
Physicochemical property: the mixture be made up of 5 components, four viable bacteria elements are main active component.Sterling is colourless prism-shaped crystallization, fusing point 112 DEG C ~ 113 DEG C.Be soluble in benzene, ethyl acetate, chloroform, ether, acetone, dissolve in 50% solvent such as ethanol, n-hexane, water insoluble.To ultraviolet-sensitive, in the sun irradiate 2 days, decomposable asymmetric choice net 50% with property through skin LDso>2000mg/kg.Proterties sterling is colourless prism-shaped crystallization.
At present, also do not report about macro tetrolide and the composite of fluorobenzene urea.
Summary of the invention
The object of the present invention is to provide a kind of water dispersible granules and the application thereof that prevent and treat white-backed planthopper, said composition active ingredient is macro tetrolide and fluorobenzene urea, wherein the weight ratio of macro tetrolide and fluorobenzene urea is, macro tetrolide: fluorobenzene urea=10:1-25:1, serve good synergistic function by composite, decrease the consumption of agricultural chemicals, meet the trend of future society environmental protection, and consumption is low, environmental friendliness.
Technical scheme of the present invention is:

Beneficial effect of the present invention is:
Said composition is the water dispersible granules of control white-backed planthopper, significantly enhance effect, delay the generation of pest resistance to insecticide, wherein the weight ratio of macro tetrolide and fluorobenzene urea is, macro tetrolide: fluorobenzene urea=10:1-25:1, serves good synergistic function by composite, decrease the consumption of agricultural chemicals, meet the trend of future society environmental protection, and consumption is low, environmental friendliness.
Study the compound synergic of composition of the present invention, test adopts white-backed planthopper.
Toxicity index and the mixed co-toxicity coefficient (CTC value) of medicament is calculated according to the abundant method of Sun Yun.
The toxicity test result of table 1 different ratio relation Whitebacked Planthopper
As can be seen from Table 1, macro tetrolide and fluorobenzene urea composite, has very high synergistic effect, especially macro tetrolide: during fluorobenzene urea=17:1-22:1, synergistic effect is more obvious.
