Abstract
The present invention relates to a rice field weed killer with broad spectrum and weeding activity. The weed killer is prepared from auxiliary agents (carriers)and two kinds of active chemical components of anilofos and bensulfuron methyl. According to different use requirements, the auxiliary agents(carriers)can adopt fine-grained pitchstone or other materials such as pottery clay, bentonite, quartz sand, light calcium carbonate, etc. Compared with the existing various weed killers used in rice fields, the weed killer has the characteristics of broad-spectrum weeding effect, strong adaptability, low cost, no side effect on rice growth and convenient use; the weed killer is especially suitable for rice direct seeding fields, seedling fields, seedling throwing fields and transplantation fields when the weed killer is used for the prevention and kill of various weeds.
Description
The invention belongs to a kind of chemical herbicide, particularly a kind of rice direct seeding field, rice seedling bed, seedling throwing field, transplant field of being applicable to prevented and kill off the chemical herbicide of barnyard grass grass, sedge weed, broad leaved weeds.
In recent years, though China's herbicide for paddy field development is very fast, also there is not a kind of desirable chemical herbicide that can kill grass family, sedge family, broad leaved weeds cheaply again simultaneously that can be fit to all planting types so far.China's thing longitude and latitude span is big, and north-south climate difference is big, makes the rice cropping mode be variation, as live field, rice seedling bed, seedling throwing field, transplant field etc.Present stage is adapted at the weed killer herbicide of live field, rice seedling bed special use, as: sweep Fu Te, quinclorac, single because of killing the grass spectrum, and cost is expensive and can not promote the wider application transplanting the land for growing field crops.Some wide spectrum, weed killer herbicide cheaply as compound weed killer herbicides such as " second benzyl first ", " fourth west ", " benzylamino isopropyl first ", can only only limit to use at transplant field, and be not suitable in live field, the rice seedling bed uses.
Task of the present invention is to compose the weak point of single and cost costliness at having the grass extremely that exists at rice direct seeding field, rice seedling bed, the employed weed killer herbicide of seedling throwing field now, provide suitable all the rice cropping modes of a kind of energy to use, have wide spectrum and kill the grass effect, it is low to have simultaneously cost again, the rice field weed killer herbicide with broad-spectrum weed-killing activity that paddy growth is had no side effect.
Task of the present invention realizes in the following way: the rice field with broad-spectrum weed-killing activity is made up of inert carrier and 2 kinds of chemical analysis with broad-spectrum weed-killing activity with weed killer herbicide.Wherein 2 kinds of chemical analysis with broad-spectrum weed-killing activity are respectively: anilofos, bensulfuron-methyl.The proportioning of anilofos and bensulfuron-methyl weight is: 100: 1 to 100: 50.According to different instructions for uses, inert carrier can adopt pitchstone granula subtilis or other materials, as: potter's clay, bentonite, quartz sand, precipitated calcium carbonate etc.When adopting pitchstone granula subtilis or quartz sand as inert carrier, its particle diameter preferably is controlled at below 2.5 millimeters.When adopting other materials, during as inert carrier, its particle diameter preferably is controlled at below 0.44 millimeter as potter's clay, bentonite, precipitated calcium carbonate etc.
All kinds of weed killer herbicides that use in the present invention and the existing paddy field are compared, and have wide spectrum and kill the grass effect, can prevent and kill off grassy weed effectively, can prevent and kill off more than 30 kind of weeds such as cyperus, broad-leaf weeds again; Adaptability is strong, is fit to the planting type of China all paddy rice of present stage, as: live field, seedling throwing field, rice seedling bed, seedling transplant field, seedlings transplant field etc.; Cost is low; Paddy growth is had no side effect; Application process is easy, and peasant household is easy to grasp advantages such as acceptance.The present invention can adopt different application processes to adapt to the planting type of all paddy rice.
The inventor has carried out nearly 100 times year May August to 1996 nineteen ninety-five that field trial shows, the present invention is 89%～95% to the comprehensive preventive effect of all kinds of weeds, and traditional weed killer herbicide of comparison photograph has improved about 30%.Wherein, preventive effect to the barnyard grass grass is 85%～98%, preventive effect to Monochoria vaginalis is 90%～96%, preventive effect to nutgrass flatsedge is 90%～98%, to short kind preventive effect of eating is 80%～92%, is 95%～100% to the preventive effect of needle spikesedge herb, is 92%～94% to the preventive effects of four leaf duckweeds, preventive effect to mexicana is 88%～96%, is 94%～96% to the preventive effect of pondweed.Cost per mu descends 20%～40% than existing weed killer herbicide.The present invention is particularly suitable for using when rice seedling is prevented and kill off all kinds of weeds in one heart stage of two leaves.
The invention will be further described below by embodiment.
Embodiment 1:
The rice field with broad-spectrum weed-killing activity of inert carrier employing pitchstone granula subtilis with the preparation method of weed killer herbicide is: add 60 parts of pitchstone granula subtilises in agravic blender, 35 parts of anilofos are forced into 1 kilograms per centimeter 2 under constant temperature be transported in the blender, under agravic condition and constant temperature, make it to adsorb and mix.Then bensulfuron-methyl is transported in the blender for 5 parts, discharging gets final product to the uniform state.During use, under general condition, adopt the shallow water broadcast application.Amount of application inclines in 300～400 gram/public affairs according to general grasp of paddy rice different planting.
Embodiment 2:
The rice field with broad-spectrum weed-killing activity of inert carrier employing potter's clay with the preparation method of weed killer herbicide is: add 60 parts～90 parts in potter's clay in agravic blender, add 2 parts of emulsifier, 1～5 part of binding agent, 10～16 parts of anilofos, 1 part of bensulfuron-methyl again, in blender, be stirred to uniform state after discharging get final product.During use, under general condition, adopt broadcast application or spray-on process.Amount of application inclines in 300～400 gram/public affairs according to general grasp of paddy rice different planting.
Inert carrier adopts the rice field with broad-spectrum weed-killing activity of bentonite or quartz sand or precipitated calcium carbonate etc. identical with embodiment 2 with the preparation method of weed killer herbicide.
Claims (2)
1, a kind of rice field weed killer herbicide with broad-spectrum weed-killing activity, it is characterized in that this weed killer herbicide is made up of inert carrier pitchstone granula subtilis and 2 kinds of activity chemistry composition anilofos and bensulfuron-methyl, wherein the weight proportion number range of anilofos and bensulfuron-methyl is: 7～16: 1.
2, the rice field weed killer herbicide with broad-spectrum weed-killing activity according to claim 1 is characterized in that the particle size range of pitchstone granula subtilis is controlled at below 2.5 millimeters.
