Abstract
The invention discloses a lotus-rhizome-field herbicide composition containing clomazone and metolachlor. The composition contains two active components respectively being clomazone and metolachlor, the ratio of clomazone to metolachlor is 0.1:1-10:2, and the components of the composition also comprise an auxiliary agent and a carrier. The herbicide composition is applicable to control of weeds in a lotus rhizome field.
Description
Technical field
The invention belongs to the agriculture plant protection field, relate to a kind of lotus rhizome field herbicidal that comprises clomazone and isopropyl methoxalamine.
Background technology
Clomazone (clomazone) chemical name: 2-(2-chlorobenzyl)-4,4-dimethyl isoxazole-3-ketone.Clomazone is the selectivity preemergence herbicide, has inner sucting conduction type, can pass through root, young shoot absorption, upwards be transmitted to each position of plant with transpiration, the sensitive plant Chlorophyll biosynthesis is suppressed, although can rudiment be unearthed, but non-pigment, albefaction, dead in a short time.The special metabolism of tool on soybean, sugarcane, lotus rhizome and drug resistance plant makes this medicament become nontoxic degradation product.The solvability of clomazone in water is larger, with soil, moderate cohesive is arranged, and the biologically active in soil is sustainable more than 6 months, in soil mainly by microbial degradation.This weed killer herbicide is mainly prevented and kill off annual gramineous weed and the part broad leaved weeds such as barnyard grass, green foxtail, lady's-grass, eleusine indica, black nightshade, elscholtiza, water sour jujube pin, kitchen garden, lamb's-quarters, knotweed, Siberian cocklebur, penny cress, piemarker.
Isopropyl methoxalamine (metolachlor) chemical name: 2-ethyl-6-methyl-N-(1 '-methyl-2 '-methoxyethyl) chloro acetanilide.Isopropyl methoxalamine is the selectivity preemergence herbicide, mainly absorbs by young shoot, and upwards conduction suppresses the growth of young shoot and root, and the protein of main sprout inhibition seed is synthetic, and next suppresses choline and infiltrates phosphatide, disturbs lecithin to form.The energy force rate broad leaved weed that absorbs isopropyl methoxalamine due to the grassy weed young shoot is strong, thereby the effect that this medicine is prevented and kill off grassy weed is better than broad leaved weed far away.
Summary of the invention
The purpose of this invention is to provide a kind of lotus rhizome field herbicidal composition with synergistic effect, the plurality of advantages such as this herbicidal composition has efficiently, low toxicity, low cost all have good preventive effect to grass family, sedge family and broad leaved weed.
The invention provides a kind of lotus rhizome field herbicidal composition, said composition comprises clomazone and two kinds of active components of isopropyl methoxalamine, adds the formulations of pesticide of insecticides adjuvant, bearer configuration one-tenth.Can be any one in wetting powder, particulate Liu, missible oil, aqueous emulsion, microcapsule formulations.
Two kinds of active component clomazones in the present invention and the proportioning of isopropyl methoxalamine are 0.5: 1～10: 1.
Involved in the present invention to auxiliary agent be NNO, pull open powder, dodecyl sodium sulfate, sodium lignin sulfonate or calcium, carboxymethyl cellulose, being used for the emulsifier such as agriculture breast No. 500, No. 600 of emulsification, can be the mixture of one or more above arbitrary proportions.
Involved in the present invention to 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, bentonite, dimethylbenzene, toluene, mineral oil, plant oil etc.
Herbicidal composition of the present invention is used for lotus rhizome Tanaka by pesticide-clay mixture method or mispickel method.
Active component clomazone of the present invention and isopropyl methoxalamine are used jointly, and test shows to have synergistic effect.Specific activity uses single composition more remarkable.The dosage that synergistic effect shows as wider weeds control spectrum, use is lower, the control efficiency that the herbicide effect onset is faster, more lasting.Just can control well the lotus rhizome field weed by applied once.
Herbicidal composition of the present invention is easy to use, cost is low, and to lotus rhizome growth safety, it applies huge economic benefit and social benefit.
Embodiment
Embodiment 1
The mass fraction of each component is: clomazone 16%, isopropyl methoxalamine 10%, and dodecyl sodium sulfate 1%, NNO 5%, auxiliary agent 82066%, white carbon 20%, kaolin is added into 100%, is mixed with 26% wetting powder.
Embodiment 2
The mass fraction of each component is: clomazone 18%, isopropyl methoxalamine 8%, and dodecyl sodium sulfate 2%, NNO 5%, auxiliary agent 82066%, perlite 40%, kaolin is added into 100%, is mixed with 26% granula subtilis.
Embodiment 3
26% clomazone isopropyl methoxalamine wetting powder in embodiment 1 is prevented and kill off the lotus rhizome field weed, table 1 is 45 days each preventive effects between processing after 26% clomazone isopropyl methoxalamine wetting powder dispenser in embodiment 1, and the contrast medicament is 480 grams per liter clomazone missible oil and 72% isopropyl methoxalamine missible oil.
Table 1.26% clomazone isopropyl methoxalamine wetting powder is prevented and kill off the preventive effect (after medicine 45 days) of lotus rhizome field weed
As can be seen from the above table, when 26% clomazone isopropyl methoxalamine wetting powder consumption was 40-50 g/acre, preventive effect was better than clomazone and isopropyl methoxalamine single dose, and each is processed lotus rhizome growth safety.
Embodiment 4
26% clomazone isopropyl methoxalamine granula subtilis in embodiment 2 is prevented and kill off the lotus rhizome field weed, table 2 is preventive effects between each processing in 45 days after 26% clomazone isopropyl methoxalamine granula subtilis dispenser, and the contrast medicament is 480 grams per liter clomazone missible oil and 72% isopropyl methoxalamine missible oil.
Table 2.26% clomazone isopropyl methoxalamine granula subtilis is prevented and kill off the preventive effect (after medicine 45 days) of lotus rhizome field weed
As can be seen from the above table, 26% granula subtilis that clomazone and different interior alachlor form has good preventive effect to the lotus rhizome field weed, and preventive effect is better than clomazone and isopropyl methoxalamine single dose generally, and each is processed lotus rhizome growth safety.
