Abstract
The invention discloses a lotus root field weedicide composition containing prometryn and metolachlor. The composition comprises two active ingredients, a wetting agent, an emulsifying agent, white carbon black and perlite, wherein the two active ingredients are prometryn and metolachlor respectively; the ratio of prometryn to metolachlor is (0.5-50): 1. The composition is suitable for preventing and removing weeds in the lotus root field.
Description
Technical field
The invention belongs to agriculture plant protection field, relate to a kind of lotus rhizome field herbicidal that comprises prometryn and isopropyl methoxalamine.
Background technology
The common malignant weed in lotus rhizome field has the weeds such as Monochoria vaginalis, duckweed, red duckweed, needle spikesedge herb, convexutricle sedge herb, barnyard grass, also has the biologies such as moss, blue-green algae simultaneously.Harm is serious.Growth and the output of lotus rhizome are affected greatly.The region of particularly planting continuously, weeds problem is the most scabrous problem during lotus rhizome is produced.Lotus rhizome field adopted artificial weeding in the past, wasted time and energy, and cost is high.
Summary of the invention
The object 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, grass family, sedge family and broad leaved weed are all had to good preventive effect, duckweed, algae, moss are had to special efficacy.
The invention provides a kind of lotus rhizome field herbicidal composition, said composition comprises prometryn and two kinds of active components of isopropyl methoxalamine, the formulations of pesticide that additional insecticides adjuvant, bearer configuration become.Can be any one in granula subtilis, missible oil, wetting powder, suspending agent, granule.
Prometryn (prometryn) chemical name: N, N`-diisopropyl-6-methyl mercapto-1,3,5-triazines-2,4-diamines.Prometryn is interior suction selective herbicide.Can absorb and conduct through root and leaf.Weeds preventive effect to firm sprouting is best, and broad weed-killing spectrum can be prevented and kill off year raw grassy weed and broad leaved weed.Be applicable to cotton, soybean, wheat class, peanut, sunflower, potato, fruit tree, vegetables, tea tree and paddy field and prevent and kill off 1 year raw grass family such as barnyard grass, lady's-grass, moleplant seed, emarginate amaranth herb or seed, knotweed, lamb's-quarters, kitchen garden, amur foxtail, chickweed, Asiatic plantain and broadleaved herb.
Isopropyl methoxalamine (metolachlor) chemical name: 2-ethyl-6-methyl N-(1 '-methyl-2 '-methoxyethyl) chloro acetanilide.Isopropyl methoxalamine is 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, secondly suppresses choline and infiltrates phosphatide, disturbs lecithin to form.Due to grassy weed young shoot, to absorb the energy force rate broad leaved weed of isopropyl methoxalamine strong, thereby the effect that this medicine is prevented and kill off grassy weed is better than broad leaved weed far away.
Two kinds of active component prometryns in the present invention and the proportioning of isopropyl methoxalamine are 0.5～50: 1.
Involved in the present invention to auxiliary agent be NNO, MF, pull open powder, sodium dodecyl, sodium lignin sulfonate or calcium, carboxymethyl cellulose, the emulsifier such as agriculture breast No. 500, No. 600, SOPA27 sulphur 0 that has been used for 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 prometryn of the present invention and isopropyl methoxalamine are used jointly, and test shows to have synergistic effect.Specific activity is used single composition more remarkable.The dosage that synergistic effect shows as wider weeds control spectrum, use is lower, herbicide effect onset sooner, more lasting control efficiency.Just can control well 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: prometryn 30%, and isopropyl methoxalamine 3%, dodecyl sodium sulfate 1%, MF5%, auxiliary agent SOPA2706%, white carbon 10%, kaolin is added into 100%, is mixed with 33% wetting powder.
Embodiment 2
The mass fraction of each component is: prometryn 45%, and isopropyl methoxalamine 5%, dodecyl sodium sulfate 2%, MF 5%, auxiliary agent SOPA2706%, perlite 25%, kaolin is added into 100%, is mixed with 50% granula subtilis.
Embodiment 3
Table 1 is the preventive effect that 33% prometryn isopropyl methoxalamine wetting powder described in embodiment 1 is prevented and kill off lotus rhizome field weed.When 33% prometryn isopropyl methoxalamine wetting powder consumption is 60-100 gram/acre, preventive effect is better than prometryn and isopropyl methoxalamine single dose, each processing lotus rhizome growth safety.
Table 133% prometryn isopropyl methoxalamine wetting powder is prevented and kill off the preventive effect (after medicine 45 days) of lotus rhizome field weed
Embodiment 4
50% prometryn isopropyl methoxalamine granula subtilis in embodiment 2 is prevented and kill off lotus rhizome field weed, table 2 is preventive effects between 45 days each processing after 50% prometryn isopropyl methoxalamine granula subtilis dispenser, and contrast medicament is 50% prometryn wetting powder and 72% isopropyl methoxalamine missible oil.
Table 250% prometryn isopropyl methoxalamine granula subtilis is prevented and kill off the preventive effect effect (after medicine 45 days) of lotus rhizome field weed
As can be seen from the above table, 50% granula subtilis of prometryn and isopropyl methoxalamine composition, has good preventive effect to lotus rhizome field weed, and preventive effect is better than prometryn and isopropyl methoxalamine single dose generally, each processing lotus rhizome growth safety.
