Abstract
The invention discloses a herbicidal composition for paddy field. The herbicidal composition contains two active ingredients including bensulfuron methyl and acetochlor. The mixture ratio of bensulfuron methyl to acetochlor is 6:16. The two active ingredients account for 22% of the total weight of the composition, and pesticide additives and carriers account for the balance. The herbicidal composition is formulated in the form of wettable powder.
Description
Technical field
The invention belongs to the agriculture plant protection field, relate to a kind of Herbicidal composition for rice field that includes bensulfuron-methyl and Acetochlor.
Background technology
Bensulfuron-methyl (bensulfuron-methyl) chemical name 2-[[[[[(4,6-dimethoxypyridin-2-yl) amino] carbonyl] amino] sulfonyl] methyl] methyl benzoate.Bensulfuron-methyl is the selectivity inner-adsorption conduction-type herbicide, can be in water rapidly diffusion, for weeds root and blade absorb and transfer to each one of weeds, hinder the biosynthesis of valine, leucine, isoleucine, stop division and the growth of cell.The susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early, and suppresses the growth of leaf section, hinders root growth and necrosis.Such weed killer herbicide is mainly prevented and kill off broad leaved weed and sedge weed, and is very low to the activity of grassy weed, and long-term a large amount of this type of weed killer herbicide that uses easily produces resistance risk.
Acetochlor (acetochlor) chemical name 2-ethyl-6 methyl--N-ethoxyl methyl-alpha-chloro acetanil.Acetochlor mainly passes through the synthetic growth that suppresses cell of impede protein matter, young shoot, young root are stopped growing, acetamide-group herbicides as extensive use, not only active high, preventive effect is good, and price is low, the annual monocotyledon weeds such as barnyard grass there is good activity of weeding, and can the double broad leaved weed of controlling the part small-sized seed, when field during take broad leaved weed as main group, herbicidal effect is often undesirable.
Summary of the invention
Purpose of the present invention is just for the deficiency of above-mentioned weed killer herbicide in practical application separately, a kind of Herbicidal composition for rice field with synergistic effect is provided, this Herbicidal combinations can enlarge the herbicide spectrum, improve activity of weeding, have the plurality of advantages such as efficient, low toxicity, low-residual, low cost, annual and part perennial weed are all had good preventive effect.
The invention provides a kind of Herbicidal composition for rice field, said composition comprises bensulfuron-methyl and two kinds of active components of Acetochlor, adds insecticides adjuvant, bearer configuration becomes wetting powder.
Two kinds of active components among the present invention account for 22% of composition total weight, and bensulfuron-methyl accounts for 6% of composition total weight, and Acetochlor accounts for 16% of composition total weight, and the proportioning of bensulfuron-methyl and Acetochlor is 6: 16.
Involved in the present invention to auxiliary agent be NNO, pull open the mixture of a kind of or more than one arbitrary proportions of powder, dodecyl sodium sulfate, sodium lignin sulfonate or calcium, carboxymethyl cellulose etc.
Involved in the present invention to used carrier be the mixture of a kind of or more than one arbitrary proportions in clay, potter's clay, diatomite, kaolin, perlite, white carbon, fine particle calcium carbonate, the bentonite etc.
Herbicidal combinations of the present invention can be used for control rice transplanting field weed, can be used for paddy field by the medicine local method, and the amount of application of this composition calculates with active component, and amount of application is generally 84-118 g/ha.
Active component bensulfuron-methyl of the present invention and Acetochlor are mixed grass family barnyard grass and broadleaved herb control are had synergistic effect, are mixed and can reduce the dosage of Acetochlor, improve Acetochlor to the safety of paddy rice.The specific activity of above-mentioned Herbicidal combinations uses single activity more remarkable.Synergistic effect show as faster, the more lasting control efficiency of wider weeds control spectrum, herbicide effect onset, by once or minority use several times just can control better and be harmful to crop and widened possible dispenser interval.These characteristics are needed in the weeds control practice process.Herbicidal combinations of the present invention is easy to use, cost is low, and to paddy growth safety, it applies huge economic benefit and social benefit, is conducive to fall this, increases production, and tallies with the national condition.
Embodiment
Embodiment 1
Bensulfuron-methyl is established 0,0.5,1.0,1.5,2.0 gram effective dose/5 levels of mu, and Acetochlor is established 0,2.4,3.7,5,6.3,7.6,8.9 gram effective dose/7 levels of mu, and totally 35 different blended combos are closed.Table 1 is behind the medicine 15 days, and bensulfuron-methyl, Acetochlor different blended combo are closed the strain preventive effect result to barnyard grass.
Table 1. bensulfuron-methyl and Acetochlor are mixed combination to the strain preventive effect (%) of barnyard grass
According to result of the test as can be known the control that is mixed to barnyard grass of bensulfuron-methyl, Acetochlor have synergistic effect.
Embodiment 2
Bensulfuron-methyl and Acetochlor are tested according to the concentration gradient that embodiment 1 arranges, and table 2 is behind the medicine 15 days, and bensulfuron-methyl, Acetochlor different blended combo are closed the strain preventive effect effect to Eclipta prostrata.
Table 2. bensulfuron-methyl and Acetochlor are mixed combination to the strain preventive effect (%) of Eclipta prostrata
According to result of the test as can be known the control that is mixed to Eclipta prostrata of bensulfuron-methyl, Acetochlor have synergistic effect.
Embodiment 3
According to the test result analysis of embodiment 1 and embodiment 2, bensulfuron-methyl and Acetochlor all have synergistic effect to the Eclipta prostrata of barnyard grass gramineous and broadleaved herb, and it is scientific and reasonable that bensulfuron-methyl and Acetochlor are mixed.From herbicide spectrum, integrated control effect, safety and the economic factor of paddy rice are considered the best proportioning of bensulfuron-methyl and Acetochlor mixture is bensulfuron-methyl: Acetochlor=6: 16.
Embodiment 4
