Abstract
The herbicide for wheat field consists of thifensulfuron and methoxone sodium salt in the weight ratio of 1 to 30-50. The herbicide has 60 % reduced thifensulfuron and methoxone sodium salt consumption, and is safe to post crop, has wide herbicidal spectrum, high herbicidal effect and delayed resistance, especially to cordate houttuynia, field bindweed, etc.
Description
One, technical field
A kind of cornfield herbicidal relates to a kind of by thifensulfuronmethyl and the composite cornfield herbicidal that forms of mcpa sodium.
Two, background technology
Thifensulfuronmethyl, mcpa sodium all are wheatland weed killer herbicides preferably.The thifensulfuronmethyl weed killer herbicide, be mainly used in winter wheat, prevent and kill off annual and perennial broadleaf weed, action principle: this product belongs to selectivity inner sucting conduction type sulfonylurea herbicide, be the side chain amino acid synthetic inhibitor, broad leaved weed absorbs rapidly and transfers to the body inner meristem through blade face and root system, suppresses the biosynthesis of valine and isoleucine, thereby the prevention cell division reaches the purpose of cutting weeds extremely.The registered thifensulfuronmethyl list agent consumption (referring to active ingredient) that is used for winter wheat is 18～35 gram/hectares.The mcpa sodium weed killer herbicide is mainly used in the control of weeds of gramineous crops such as control wheat, barley, corn, millet, jowar.Action principle: mcpa sodium is a phenoxy acetic acid parahormone selective herbicide, have stronger interior suction conductivity, when low concentration, can suppress growth and development of plants, cause the appearance deformity, up to death, cauline leaf is handled after being mainly used in seedling, and the synthetic generation Different Effects to nucleic acid and protein stops growing growing point, not tensible of young leaflet tablet, suppress photosynthetic and normally carry out, be transmitted to the medicament of plant bottom, promote abnormal cell division, the tip of a root expands, the forfeiture absorbing capacity causes the cane distortion, deformity, screen casing stops up, phloem destroys, and the organic matter transportation is obstructed, and causes plant death.The registered wheat that is used for is prevented and treated multiple weeds, and the usage amount of active ingredient is 600～900 gram/hectares.The thifensulfuronmethyl that remains in the field easily causes poisoning to second stubble crop (peanut, cotton), when the mcpa sodium consumption is bigger than normal, can cause wheat yield; Simultaneously, along with sulfonylurea herbicide extensive use in wheatland, weeds develop immunity to drugs to this type of medicine gradually, and sulfonylurea herbicides such as thifensulfuronmethyl use the plot in several years continuously, and field bindweed weeds amount obviously rises.
Three, summary of the invention
The object of the present invention is to provide a kind ofly, can delay or avoid weeds to develop immunity to drugs, the weed killer herbicide of broad weed-killing spectrum succession crop and wheat safety.
For achieving the above object, the performance according to thifensulfuronmethyl and mcpa sodium is mixed according to a certain percentage to the two, with thifensulfuronmethyl, the mcpa sodium weed killer herbicide is for contrast, in the field or the indoor test of pesticide effectiveness of carrying out, according to result of the test, filter out best proportioning.
Cornfield herbicidal of the present invention, the weight proportion behind thifensulfuronmethyl and the mcpa sodium folding hundred is 1: 30～1: 50.Weight proportion behind preferred thifensulfuronmethyl and the mcpa sodium folding hundred is: 1: 35～1: 40.Most preferably being the weight proportion of thifensulfuronmethyl and mcpa sodium folding after hundred is 1: 36～1: 38.
The existing thifensulfuronmethyl weeding of the present invention characteristics have mcpa sodium weeding characteristic again.Through field experiment, complex weedicide of the present invention, than thifensulfuronmethyl, mcpa sodium list agent broad weed-killing spectrum, preventive effect height.At first, reduced the mu time consumption of thifensulfuronmethyl, when single agent prevents and treats, active ingredient is 18～35 gram/hectares, and when adopting weed killer herbicide of the present invention to prevent and treat, the active ingredient of thifensulfuronmethyl is 7～14 gram/hectares, reduce 60% than conventional amount used, the succession crop safety coefficient is increased; Secondly, reduced the mu time consumption of mcpa sodium, when single agent prevents and treats, the active ingredient of mcpa sodium is 600～900 gram/changes hectare, when adopting weed killer herbicide of the present invention to prevent and treat, the active ingredient of mcpa sodium is 330～450 gram/hectares, reduces 50% than conventional amount used, prolonged the mcpa sodium operating period, strengthened the safety of mcpa sodium wheat; The 3rd, thifensulfuronmethyl, mcpa sodium mechanism of action difference, weeds difficult labour give birth to resistance, delay or reduced pesticide resistance, the especially shepherd's purse of weeds generations, descurainia sophia (l.) webb ex prantl, weeds such as field bindweed are the wheatland of sociales, control efficiency is better.
Weed killer herbicide of the present invention can be prevented and treated Tong fiber crops, wild garlic, the edge of a field amaranth, Amaranthus retroflexus, wrinkle fruit amaranth, Maruta cotula, shepherd's purse, lamb's-quarters, dayflower, descurainia sophia (l.) webb ex prantl, elscholtiza, meadow pine, wallflower, weasel hemp nettle, Herba Galii Teneri, rule grass, summer cypress, Ben Shi knotweed, volume stem knotweed, pale persicaria, red shank, kitchen garden, salsola collina, Veronica, rice crock, black nightshade, corn sow thistle, the quick thread of ox, chickweed, penny cress, can prevent and treat field bindweed, Siberian cocklebur, field thistle, ion grass, convexutricle sedge herb etc. again.After one day, main weeds descurainia sophia (l.) webb ex prantl cauline leaf curls in the wheatland dispenser, shows mcpa sodium weeding symptom; After seven days, show the growing point jaundice, suppressed, show thifensulfuronmethyl weeding symptom.
Four, embodiment
