Abstract
The invention discloses a weeding composition comprising HNPC-A8169 and fluroxypyr. The composition is characterized in that a weight ratio of HNPC-A8169 to fluroxypyr is 1: 60 to 2:1, and the sum of the weight of HNPC-A8169 and fluroxypyr is 1-50% of the total weight of the composition. A large number of indoor and outdoor tests prove that the composition can be processed into an emulsifiable concentrate, an aqueous emulsion, a suspending agent, a microemulsion, wettable powder and water dispersible granules used for preventing and treating weeds in a cereal crop field, and has the advantages of high pharmacological effect, little dosage, wide herbicide controlling spectrum, etc. The preventing and treating effects of the composition are improved obviously than those of a single dosage; in addition, the use dosage of a pesticide is reduced; grassy weeds and broadleaf weeds in the cereal crop field can be prevented or weeded effectively when the dosage per mu is 6-12g; an obvious synergistic or additive effect is shown; the labors and cost for composition application are saved; and influences to the environment and pesticide residues are reduced. The limitation that the single agent is narrow in weed control spectrum is overcome; the weed control spectrum is expanded; the grassy weeds and the broadleaf weeds in the crop field can be prevented or weeded by once composition delivery; and the composition is safe to crops.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, contained effective ingredient is the propargyl epoxide of n--(r) -2- [4- (chloro- 3- of 5-
Fluoro- 2- pyridyloxy) phenoxy group] propionic acid (test code number be hnpc-a8169) and fluroxypyr, for Cereal
The crop fields grassy weed and the preventing and treating of broad leaved weed.
Background technology
Chemical name is the propargyl epoxide of n--(r) -2- [4- (the chloro- 3- of 5- fluoro- 2- pyridyloxy) phenoxy group] propionic acid
(test code number is hnpc-a8169).The chemical structural formula of hnpc-a8169 is:
Hnpc-a8169 can effectively suppress lipid biosynthesiss in class plant, belongs to acetylcoenzyme a hydroxylase inhibitors,
Can be used for the preventing and treating of the cereal crop field grassy weed such as Semen Tritici aestivi, Fructus Hordei Vulgaris, such as amur foxtail, rat-tail amur foxtail, wild oat, rye (Secale cereale L.)
Grass, annual bluegrass, Herba Setariae Viridis, Triticum tauschii etc..
Fluroxypyr (fluroxybyr), chemical name is 4- amino -3,5- bis- chloro- 6- fluoro- pyridine -2- oxygen second
Acid, is organic heterocyclic class selectivity inner sucting conduction type herbicide after seedling, belongs to typical hormone like herbicide, on chemical constitution is shown in
Formula.Fluroxypyr is absorbed by plants after applying quickly, makes sensitive plant the reaction of classical hormones class herbicide, plant
Deformity, distortion, finally withered it is adaptable to broad-leaved is prevented and kill off on the ground such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Semen Maydiss, Fructus Vitis viniferae, orchard, pasture, forest land, lawn
Weeds.In drug resistance plant body, fluroxypyr is combined into conjugatess and loses toxicity, thus having selectivity.Temperature
The weeding final effect of fluroxypyr is no affected, but affects the speed of its drug effect performance, drug effect typically when temperature is low
Play relatively slow, stop growing after dunsiekte can be made, but not dead immediately, and after temperature raises, plant is dead quickly.But due to this
The large area of several years fluroxypyrs uses, and weeds have produced different degrees of Drug resistance to it, and field using dosage is continuous
Soaring, use cost more and more higher.
The herbicide mixture of the different mechanisms of action, has that herbicidal spectrum is wide, lifts actual effect, delays herbicide resistance, province
Shi Shenggong advantage.Screened by formulation of pesticide, actual prevention effect can be effectively improved, reduce dosage, reduces cost, delay
The drug-fast generation of disease, worm, crop smothering, is important means, therefore hnpc-a8169 and the fluroxypyr that agricultural synthesis are administered
Mixture uses has positive meaning.
Not yet there is the report of hnpc-a8169 and fluroxypyr mixture at present.
