Abstract
The invention discloses a mixed herbicide comprising the following constituents: nicosulfuron 3-50%, S-metolachlor 10-77%, emulsifying agent 5-15%, and balancing dimethylbenzene. The invention can realize a prevention and curing effect of over 96%.
Description
Technical field
The present invention relates to a kind of weed killer herbicide.
Background technology
Nicosulfuron is a corn herbicide, behind the low dosage bud with preventing and kill off broad leaved weed and sedge weed in the corn field effectively.Use the back weeds and stop growing immediately, 4-5 days young leaves fade, necrosis, and progressively expand to whole plant, and general condition is handled back plant death in 20-25 days down.Corn has drug resistance preferably to this medicine, handles the back and temporary transient chlorisis or slight hypoevolutism occur, but generally can recover rapidly and the not underproduction.
Isopropyl methoxalamine is the selectivity preemergence herbicide, and annual gramineous weed is had favorable effect.
Can present crop smotherings such as corn field grassy weed, broad leaved weed and sedge weed be more serious, develop and can prevent and kill off grassy weed, can prevent and kill off the broad leaved weed agricultural chemicals again, become cornfield weeding one big problem.
Summary of the invention
At the problem of above-mentioned existence, the object of the present invention is to provide a kind of better effects if, stablize and can prevent and treat grassy weed, broad leaved weed mixed herbicide.
For achieving the above object, a kind of mixed herbicide of the present invention comprises following component: nicosulfuron 3-50%, and isopropyl methoxalamine 10-77%, emulsifier 5-15%, surplus is a dimethylbenzene.
Further, described emulsifier is optional: nonionic surface active agent or anionic surfactant, described non-ionic surface active agent is phenyl xenol polyvinylether, phenethyl phenol polyethenoxy ether, phenethyl phenol polyethenoxy polyoxy third rare ether, polyoxyethylene nonylphenol ether or alkylphenol polyoxyethylene formaldehyde condensation products etc., and described anionic surfactant is the poly-nitrogen vinethene sulphate of sodium alkyl benzene sulfonate, C8-C20 sodium alkyl sulfate or styrene.
Control efficiency of the present invention can reach more than 96%.
The present invention has synergistic effect: by Toxicity Determination, the complex preparation nicosulfuron: the co-toxicity coefficient of isopropyl methoxalamine (3: 77), (10: 70) and (40: 40) is respectively 162.81,170.76 and 180.91.The co-toxicity coefficient of three processing has synergistic effect all greater than 100.
The present invention has expansion and kills the grass spectrum: by Toxicity Determination, nicosulfuron is to broad leaved weed preventive effect height, and is also better to the grassy weed preventive effect.Isopropyl methoxalamine is then to the anti-heterodyne of broad leaved weed, and to grassy weed preventive effect height, both are composite to complement each other later, and to all obviously raisings of preventive effect of grassy weed, broad leaved weed, expansion is killed grass and composed.
Embodiment
Embodiment 1
According to nicosulfuron 40%, isopropyl methoxalamine 40%, phenyl xenol polyvinylether 10%, the ratio of dimethylbenzene 10% takes by weighing each component, puts into reactor then and carries out shear agitation, filters afterwards, detection, can get final product.
During use, blend water according to every mu of 60-80 gram, spraying then.
Embodiment 2
According to nicosulfuron 3%, isopropyl methoxalamine 77%, phenethyl phenol polyethenoxy ether 5%, the ratio of dimethylbenzene 15% takes by weighing each component, and all the other steps are with embodiment 1.
Embodiment 3
According to nicosulfuron 10%, isopropyl methoxalamine 70%, sodium alkyl benzene sulfonate 15%, the ratio of dimethylbenzene 5% takes by weighing each component, and all the other steps are with embodiment 1.
In addition, emulsifier can also be selected non-ionic surface active agents such as phenethyl phenol polyethenoxy polyoxy third rare ether, polyoxyethylene nonylphenol ether or alkylphenol polyoxyethylene formaldehyde condensation products, also can select anionic surfactant such as the poly-nitrogen vinethene sulphate of C8-C20 sodium alkyl sulfate or styrene.
Claims (2)
