Abstract
The invention relates to a weeding composition which comprises fluroxypyr, bentazone and acceptable auxiliary components in pesticides, wherein the fluroxypyr and the bentazone are used as active components, and the weight percent of the fluroxypyr to the bentazone is 4:1-1:48. By combining the two active components, the weeding composition can have synergy, can prevent and remove various kinds of broad leaved weeds and sedge weeds, obviously improves the weeding effect, and reduces the production cost.
Description
Technical field
The present invention relates to a kind of herbicidal composition, particularly can be used for the herbicidal composition of paddy field, wheat paddock, corn field, sugarcane field, orchard and uncultivated area.
Background technology
In the cultivation process such as paddy field, wheat paddock, corn field, the extensive use of weed killer herbicide expands cultivated area to controlling weeds harm effectively, improves output, improves product quality, saves recruitment, regulates the labour and plays an important role.At present the weed killer herbicide in these crop farmlands has all been developed a lot of kinds, but because its careless extremely spectrum is single, or the similar approximate weed killer herbicide of long-term single use, the succession and the weeds pesticide resistance that make weed community distribute strengthen day by day.
Fluroxypyr (fluroxypyr) is a pyridine fluoroacetic acid class weed killer herbicide, and structure is a cauline leaf inorganic agent behind a kind of selectivity, internal-suction type, the seedling suc as formula shown in (I), is absorbed by the weeds cauline leaf.Absorbed by weeds very soon after the dispenser, the reaction of typical hormone herbicide appears in susceptible weeds, and plant deformity, distortion are finally withered.Can effectively prevent and kill off multiple annual, perennial broad leaved weed, be applicable to that wheat, barley, corn, paddy rice (rice seedling bed, live field, seedling throwing field, transplant field, furrow side), orchard etc. prevent and kill off multiple broad leaved weed; As Monochoria vaginalis, water peanut, angustifolia arrowhead herb, clearvers, volume stem knotweed, kitchen garden, black nightshade, field bindweed, knotweed, amaranth etc., invalid to grassy weed.
Bentazone (bentazon) is an optionally herbicide after seedling of contact killing type tool, structure is suc as formula shown in (II), be used for cauline leaf processing in seedling stage, work by the blade contact, be a kind of broad spectrum weeding agent, can be used for various crop Tanakas such as paddy rice, wheat, soybean, corn, pea and prevent and kill off broad leaved weed and sedge weed.Dry land is used, and is transmitted to by the blade face infiltration earlier and suppresses photosynthesis in the chloroplast.The paddy field is used and can be absorbed by root again by the blade face infiltration, is transmitted to cauline leaf, hinders weeds photosynthesis and water metabolism strongly, causes nutrition hunger, makes physiological function lack of proper care and cause death.
Summary of the invention
At above-mentioned situation, the present invention will provide a kind of can prevent and kill off broad leaved weed, can prevent and kill off the highly effective and safe weeding agricultural chemicals of sedge weed again, solves the problem that present herbicide effects reduces gradually.
The present invention is to provide a kind of Herbicidal combinations, be to be active ingredient with fluroxypyr and bentazone, form jointly with acceptable auxiliary element in the agricultural chemicals, the percentage by weight of fluroxypyr and bentazone is 4: 1～1: 48, better ratio is 2: 1～1: 24, and preferred ratio is 1: 3～1: 12.

Following result of the test can show, in the above-mentioned Herbicidal combinations of the present invention, two active ingredient fluroxypyrs and bentazone can the tool obvious synergistic effect, can prevent and kill off broad leaved weed, can prevent and kill off nutgrass flatsedge again, and improve herbicidal effect, reduce production cost.
Existing studies show that, when different herbicidal compositions were used in combination, if then should there be synergistic effect in the activity of weeding after the combination during active when surpassing separate constituent and using.The expectation activity of two kinds of herbicidal compositions under given combination can have formula to calculate (referring to, Colby, SR., Calculating synergistic and antagonistic response of herbicidecombination, Weed 15, pp 20-22,1967):
If at amount of application is under the situation of p kg/ hectare, the loss ratio of weed killer herbicide A is X%; Be that weed killer herbicide B loss ratio is Y% under the situation of q kg/ hectare at amount of application; Be under the situation of p and q kg/ha at amount of application then, the speculative damage rate of weed killer herbicide A and B is E%, wherein E=X+Y-X*Y/100.If actual damage surpasses calculated value, the activity of composition is super adduction, i.e. its demonstration synergy.
Can prove the preventive effect of the above-mentioned Herbicidal combinations of the present invention by following correlation test result.
Test one: results from pot experiment test is as shown in table 1.Wherein Monochoria vaginalis is the 2-4 leaf phase, clearvers 2-3 wheel blade.
The composite indoor virulence of table 1 fluroxypyr and bentazone to broad leaved weed
Test two: field control effectiveness test result
Wherein, behind the rice transplanting 14 days, the weeds 3-4 leaf phase, shown in the table 2 was that the preventive effect result of 30 days investigation fresh weights after the dispenser is as shown in table 2.
To the wheat 3-4 leaf phase, the weeds 3-4 leaf phase, 45 days investigation fresh weight preventive effects are as a result shown in the table 3 after the dispenser.
To the corn 4-5 leaf phase, the weeds 3-5 leaf phase, 30 days investigation fresh weight preventive effect results are as shown in table 4 after the dispenser.
The composite test of pesticide effectiveness result who prevents and kill off the paddy field broad leaved weed of table 2 fluroxypyr and bentazone
The composite test of pesticide effectiveness result who prevents and kill off the wheat paddock broad leaved weed of table 3 fluroxypyr and bentazone
The composite test of pesticide effectiveness result who prevents and kill off the corn field broad leaved weed of table 4 fluroxypyr and bentazone
Show by table 2,3,4 result of the test, by the reduce by half composition of medicine of back combination of two kinds of single-dose things, preventive effect in four kinds of different weeds tests all is higher than the single-dose thing of full dosage respectively, and most statistical dispositions have all showed the difference of significance, illustrate that fluroxypyr and bentazone can have significant synergistic effect after composite, and there is not antagonism, to paddy rice, wheat, corn safety.
