Abstract
The invention provides herbicide composition containing carfentrazone-ethyl, fluroxypyr and atrazine. A weight ratio of the carfentrazone-ethyl, the fluroxypyr and the atrazine is 0.1-30: 1-30: 1-35. The herbicide composition can be used for preparing a conventional dosage form. The herbicide composition can obviously improve a pesticide effect. A control effect for grassy weeds is 85.1%-99.2%. A control effect for broadleaf weeds is 83.9%-100.0%. In the aspect of a comprehensive control effect, a control effect of the carfentrazone-ethyl is 63.2%-69.8%, a control effect of the atrazine is 48.5%-54%, and a control effect of the fluroxypyr is 41.6%-46.6%. The comprehensive control effect of the composition is 82.5%-99.9%. Therefore, the control effect of the herbicide composition is improved significantly, and synergism is significant.
Description
Technical field
The invention belongs to the agricultural herbicide technical field, relate to a kind of agricultural herbicide composition and method for making that contains benzene azoles humulone, fluroxypyr and atrazine herbicidal.
Background technology
At present, in corn field, the malignant weeds appearance such as drug effect relatively poor phenomenon, especially barnyard grass, Commelina communis, piemarker, the rhizome of nutgrass flatsedge generally appear in the sealing weeding, and corn yield has been caused very large impact.Benzene azoles humulone can be prevented and kill off corn field annual gramineous weed and broad leaved weed.Atrazine is before interior suction selectivity seedling, herbicide after seedling, and root absorption is main, and cauline leaf absorbs seldom.Be applicable to corn, Chinese sorghum, sugarcane, tea place, rubber and orchard, nursery and prevent and kill off 1 year living broadleaved herb such as green foxtail, india lovegrass, speedwell, nutgrass flatsedge, Siberian cocklebur, Eclipta prostrata, emarginate amaranth herb or seed, feather cockscomb, kitchen garden, grey dish, flowerofanhour root or herb, bluish dogbane, lady's-grass, yard grass, barnyard grass, convexutricle sedge herb, cyperus iria L. rhizoma scirpi, three-coloured amaranth, wolf's milk, acalypha copperleaf, lamb's-quarters and grassy weed.Its easily by rainwater drip washing to soil than deep layer, also effective to some dark root grass, but easily produce poisoning, the lasting period is also longer.The different monooctyl ester of fluroxypyr or fluroxypyr: can prevent and kill off clearvers, volume stem knotweed, kitchen garden, black nightshade, chickweed, common vetch, field bindweed, weasel hemp nettle, pale persicaria, willow leaf thorn knotweed, Amaranthus retroflexus, dayflower, elscholtiza, penny cress, vetch, broadcast the broad leaved weeds such as ma wormwood artemisia and little japanese bearbind, invalid to grass family and sedge weed.Up to now, in the agricultural herbicide technical field, the precedent that the three is composite is arranged not yet.
