Abstract
The invention discloses a miticide composite containing fenisobromolate and diafenthiuron, and relates to a pesticide composite, in particular to the pesticide composite used for killing acarids agriculturally. The active ingredient of the pesticide composite used for killing acarids is the mixture of the fenisobromolate and the diafenthiuron. The weight ratio between the fenisobromolate and the diafenthiuron is 1:10 or 10:1, the weight percentage of the active ingredient is 1-80%, and suspending agent can be prepared by adopting the method of universal preparation according to the actual needs. The fenisobromolate and the diafenthiuron are selected as the active ingredients of the miticide composite, the formulation is reasonable, so that the deficiencies of strong fastness of diafenthiuron, high controlling cost caused by a large quantity of usage and low acaricidalactivity of the fenisobromolate are made up, and the synergy is remarkable. The experiments proves that the miticide composite can quickly kill the acarids, the effects can last for a long time, the yield and quality of the crops are guaranteed while the controlling effect is ensured, and the miticide composite can meet the needs of agricultural industry at present.
Description
Technical field
The present invention relates to composition pesticide, especially agricultural goes up and uses a kind of miticide composition that contains fenisobromolate and butyl ether urea.
Background technology
Acarid is commonly called as two spotted spider mite, is a kind of serious biology that endangers on agricultural, and the conventional pesticide that is used at present preventing and treating very easily develops immunity to drugs owing to repeatedly using, and prevents that cost is also higher;
Fenisobromolate, (bromopropylate) chemical name: 4,4 '-dibromo diphenylglycollic acid isopropyl ester, structural formula is:
This compound is a kind of to kill that the mite spectrum is wide, the lasting period is long, toxicity is low, to the safer miticide of natural enemy, honeybee and crop.Tagging property is stronger, and absorption in not having is to becoming, as if mite and ovum certain lethal effect being arranged all.Variations in temperature is little to the drug effect influence.This medicine is applicable to crops such as cotton, fruit tree, vegetables and tea, can prevent and treat multiple harmful mites such as tetranychid, goitre mite, line mite.The evil mite has cross resistance to this medicine and dicofol, will note during use.
The butyl ether urea, (diafenthiuron), chemical name: 1-tertiary butyl-3-(2,6-diisopropyl-4-Phenoxyphenyl) thiocarbamide, structural formula is:
Be a kind of new type disinsection, miticide, be widely used on cotton, fruit, vegetables and the tealeaves.This medicine is a kind of selective insecticide, inhale and fumigation action in having, the sensitive strain that can control aphid reaches the aphid that carbamate, organic phosphor and pyrethroid is produced resistance, and cicadellid and coconut palm aleyrodid etc. can also be controlled diamond-back moth, imported cabbageworm and noctuid and cause harm.This medicine can be used with most of insecticides tested and bactericide.
