Abstract
The invention discloses a ternary weed-killing composition for a corn field. The ternary weed-killing composition is characterized in that halosulfuron methyl, bentazone and atrazine are adopted as effective components, and the weight rate of the halosulfuron methyl, the bentazone and the atrazine is (10-20):(1-5):(3-15). The ternary weed-killing composition has the characteristic of wide weed killing spectrum, and also has the advantages that a higher synergistic effect can be generated, the control effect of the composition is obviously improved compared with that of a single agent, the use dosage of the pesticide is reduced, the use times of the pesticide are reduced, the production cost is reduced and the influence of the pesticide on the ecological environment is reduced.
Description
?
Technical field
The present invention relates to a kind of Herbicidal combinations, specifically is a kind of ternary weeding composition for corn field.
Background technology
Corn is one of China staple crops, is the second largest crops that are only second to paddy rice.But, the most of corn field of China has the generation of crop smothering in various degree over the years, the weeds of main harm corn field have lady's-grass, barnyard grass grass, green foxtail, eleusine indica, Amaranthus retroflexus, kitchen garden etc., these weeds kinds are many, distribution is wide, growing power is vigorous, the individual plant area coverage is big, fight for space, nutriment in a large number with corn, cause corn growth to be restricted, directly influence maize yield and quality, and have the greatest impact seedling stage, can cause that milpa is short and small, bar spire Huang etc. has a strong impact on the corn quality, but underproduction amplitude reaches 35%.Therefore, domestic corn field is extensive use of weed killer herbicide, avoids corn because of the weeds underproduction.
Halosulfuronmethyl, chemical name: 3-chloro-5-(4,6-dimethoxypyridin-2-base amino carbonyl amino sulfonyl)-1-methylpyrazole-4-carboxylate methyl ester.Absorb by weeds root and leaf, conduct in plant corpus, weeds namely stop growing, and are then withered.Be mainly used in preventing and kill off broad leaved weed and sedge weed, as datura, Amaranthus retroflexus, flowerofanhour root or herb, kitchen garden, Cassia tora, the rhizome of nutgrass flatsedge etc., suitable crop such as wheat, corn, paddy rice sugarcane, lawn etc.Reaching Miao Houjun before the seedling can use, because its rapid metabolism in crop is harmless object, so to crop safety.
Bentazone is optionally contact killing type herbicide after seedling of a kind of tool, is used for weeds cauline leaf in seedling stage and handles.Prevent and kill off broad leaved weed and sedge weed.
Atrazine, chemical name: 2-chloro-4-diethylin-6-isopropylamine base-1,3,5-triazines.Broad weed-killing spectrum mainly absorbs by plant root and upwards conduction, suppresses the photosynthesis of weeds, makes it withered.Can prevent and kill off multiple annual gramineous weed and broad leaved weed.Be applicable to dry crops such as corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land.
Summary of the invention
The object of the present invention is to provide a kind of ternary weeding composition for corn field.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of ternary weeding composition for corn field, it is characterized in that: it is the ternary weeding composition that active ingredient is formed by halosulfuronmethyl, bentazone and atrazine, and the parts by weight ratio of halosulfuronmethyl, bentazone and atrazine is 10-20:1-5:3-15 in this ternary weeding composition.
The parts by weight ratio of halosulfuronmethyl of the present invention, bentazone and atrazine is 15:3:10.
Beneficial effect of the present invention: ternary weeding composition of the present invention has the wide characteristics of herbicidal spectrum, can produce higher cooperative synergism, the control efficiency of composition is significantly improved than single agent, reduce the agricultural chemicals using dosage, reduce the medication number of times, reduce production cost, reduced agricultural chemicals to the influence of ecotope.
Embodiment
Below in conjunction with specific embodiment the present invention is further described.
Embodiment 1
Press column weight amount umber and take by weighing raw material: 15 weight portion halosulfuronmethyls, 3 weight portion bentazones, 10 weight portion atrazines, 6 weight account polyethylene alcohol, 7 weight portion methylcellulose, 11 weight portion kaolin, above-mentioned substance is evenly mixed, mask, mix suitable quantity of water and granulation, obtain water dispersible granules after the drying.
Embodiment 2
