Abstract
The present invention relates to a weed killer with broad-spectrum weeding activity. The weed killer is prepared from an auxiliary agent and metolachlor, bensulfuron-methyl and metsulfuron-methyl used as activity chemical components. According to different use requirements, the auxiliary agent can adopt pitchstone granule auxiliary agents or organic solvents. Compared with traditional weed killers, the weed killer has the characteristics of broad-spectrum weeding effect on thirty-odd weeds such as gramineae, sedge family and broadleaf weeds, etc., low cost, no side effect on the growth of rice and simple use method, and the weed killer is especially suitable for being used as a chemical weed killer for preventing and killing weeds in rice fields.
Description
The invention belongs to a kind of chemical herbicide, particularly a kind of chemical herbicide that is used for the paddy field management of weeds.
Mu paddy field surplus China has 500,000,000, wide farmers generally is used for preventing and kill off paddy land weed to chemical herbicide.The kind of the herbicide for paddy field of extensive use at present has: butachlor, nitrofen, 2 first, 4 chlorine, bensulfuron etc.These traditional weed killer herbicides exist and kill the single weak point of grass spectrum, only grassy weed are had effect as butachlor and nitrofen; 2 first, 4 chlorine and bensulfuron only have effect to broadleaved herb and sedge weed.Weeds kind in the general paddy field is more, can not reach the purpose of effective management of weeds when adopting traditional weed killer herbicide to carry out single administration.Once the someone adopts the defective that the method for two or more herbicide mixtures is remedied the single administration weed killer herbicide in recent years, will certainly increase the cost of cutting weeds but do like this, and operating technology requirement simultaneously is tighter, and peasant households are difficult for grasping and accepting.
Task of the present invention is to exist at traditional weed killer herbicide to kill the single weak point of grass spectrum, provides a kind of and has wide spectrum and kill the grass effect, and it is low to have cost simultaneously again, paddy growth is had no side effect the weed killer herbicide with broad-spectrum weed-killing activity that application process is easy.
Task of the present invention is finished in the following way: the weed killer herbicide with broad-spectrum weed-killing activity is made up of auxiliary agent and 3 kinds of activity chemistry compositions, and wherein 3 kinds of activity chemistry compositions are respectively: isopropyl methoxalamine, bensulfuron, metsulfuron-methyl.According to different instructions for uses, auxiliary agent can adopt pitchstone fine particle assistant agent or organic solvent.When adopting the pitchstone fine particle assistant agent, the particle diameter of pitchstone fine particle assistant agent preferably is controlled at below 1500 microns.Organic solvent can adopt dimethylbenzene or toluene.
The present invention compares with traditional weed killer herbicide, has wide spectrum and kills the grass effect, can prevent and kill off kind of weeds surplus the grass family, sedge family, broad-leaf weeds etc. 30 of paddy field effectively, it is low to have simultaneously cost again, paddy growth is had no side effect, and application process is easy, and peasant household is easy to grasp characteristics such as acceptance.The field trial of carrying out in July, 1994 through Hainan Province's plant protection unit shows, the weed killer herbicide that the present invention has a broad-spectrum weed-killing activity is 95.2%～98.9% to the integrated control effect of all kinds of weeds, improves 15%～18% than butachlor.Wherein, the preventive effect to the barnyard grass grass is 91.9%～100%; Preventive effect to Monochoria vaginalis is 100%; Preventive effect to sedge family is 86.9%～100%; Preventive effect to the fire hose is 86.9%～100%; Preventive effect to lady's-grass is 89.2%～100%; Preventive effect to dicotyledonous grass is 88.7%～97.2%.And compare cost per mu with traditional weed killer herbicide and descend 30%.The present invention is particularly suitable as a kind of chemical herbicide that is used for the paddy field management of weeds.
The invention will be further described below by embodiment.
Embodiment 1:
Auxiliary agent adopts the manufacture craft of the weed killer herbicide with broad-spectrum weed-killing activity of pitchstone fine particle assistant agent to be: add 88.5 parts of fine particle assistant agents of pitchstone (weight ratio) in agravic blender, 10 parts of isopropyl methoxalamines are forced into 1 kilograms per centimeter 2 are transported in the blender, under 80 ℃ of temperature and agravic condition, make it to adsorb and mix.Then 1 part of bensulfuron, metsulfuron-methyl are transported in the blender for 0.5 part, mechanical rotation discharging to the uniform state gets final product.During use, under general condition, 50 these weed killer herbicides of gram are used in average every mu of paddy field.
Embodiment 2:
Auxiliary agent adopts the manufacture craft of the weed killer herbicide with broad-spectrum weed-killing activity of dimethylbenzene organic solvent to be: add 80 parts of dimethylbenzene (weight ratio) in liquid mixer, add 2 parts of emulsifier again, 1 part of diffusant, 10～15 parts of isopropyl methoxalamines, 0.5～2 part of bensulfuron, 0.3～0.8 part of metsulfuron-methyl mixes to full and uniform back discharging and gets final product under 80 ℃ of temperature condition.During use, under general condition, 50 milliliters～100 milliliters these weed killer herbicides are used in average every mu of paddy field.
Claims (1)
1, a kind of weed killer herbicide with broad-spectrum weed-killing activity, it is characterized in that this weed killer herbicide is made up of at the pitchstone fine particle assistant agent below 1500 microns and 3 kinds of activity chemistry composition isopropyl methoxalamines, bensulfuron, metsulfuron-methyls particle diameter, wherein the weight proportion numerical value between pitchstone fine particle assistant agent, isopropyl methoxalamine, bensulfuron, the metsulfuron-methyl is: 177: 20: 2: 1.
