Description
Technical field
The invention belongs to technical field of compounded pesticide, relate to a kind of corn field herbicide composition, particularly a kind of corn field herbicide composition of and atrazine grand containing benzene azoles humulone, thiophene ketone sulphur, is applicable to prevent and kill off corn field annual broadleaf weed and grassy weed.
Background technology
China is large agricultural country, and maize sown area is wide, and corn field weed occurs general, and weeds are of a great variety.Corn field weed mainly contains broad leaved weeds as Amaranthus retroflexus, lamb's-quarters, field bindweed, black nightshade, three-coloured amaranth, piemarker, iron amaranth, kitchen garden, Siberian cocklebur, dayflower, ox chickweed etc.; Grassy weed is as barnyard grass, lady's-grass, green foxtail, eleusine indica, Bermuda grass, moleplant seed etc.; Sedge weed is as the rhizome of nutgrass flatsedge etc.Weeds and corn fight for moisture, nutrient, illumination and space, affect the normal growth of Maize at Seedling Stage, even can cause Severe Reduction.People make great efforts to use chemical herbicide weeding always, but because most of weed killer herbicide herbicide spectrum own is limited, and Long-Time Service easily causes the generation of Weed Resistance, therefore need to improve existing weed killer herbicide, make it have better herbicidal effect and wider herbicide spectrum.
Benzene azoles humulone, be again benzene pyrazoles humulone, English name is topramezone, and chemical name is [3-(4,5-dihydro-3-isoxazolyl)-4-sulfonyloxy methyl-2-methylbenzene] 5-hydroxyl-1-methyl isophthalic acid H-pyrazoles-4-base) ketone, belong to pyrazoline type herbicides.Benzene azoles humulone broad weed-killing spectrum, has preventive effect to the most grassy weed of corn field and broad leaved weed, can effectively prevent and kill off the weeds in field such as green foxtail, eleusine indica, lamb's-quarters, knotweed, piemarker, kitchen garden, Siberian cocklebur, black nightshade.Benzene azoles humulone can be absorbed by the blade of weeds, root and stem, and in plant corpus Bidirectional Conduction up and down, the synthesis of remote-effects carotenoid, the synthesis under light illumination of interference chloroplast and function, finally cause the serious albefaction of weeds lobus cardiacus, necrosis, weeds are dead.At 20 DEG C, general spray medicine just can take effect for 2 ~ 4 days.Field trial shows, the corn (conventional field corn, sweet corn, pop corn, glutinous corn) of benzene azoles humulone to most type all shows extraordinary safety, being safest weed killer herbicide in domestic and international all after-seedling herbicide for maize kinds in the market, is also the herbicide after seedling that herbicide is fastest in the market.
Thiophene ketone sulphur is grand; English name is thiencarbazone-methyl, and chemical name is 4-({ [(3-methoxyl group-4-methyl-5-oxo-4,5-dihydro-1H-1; 2,4-triazol-1-yl) carbonyl] amino sulfonyl)-5-methylthiophene-3-methyl formate.Thiophene ketone sulphur is grand is sulfonyl-amino-carbnyl triazolinone class weed killer herbicide, is also a kind of inhibitor of acetolactate synthetase.In August, 2008 obtains registration in Romania, and this is that this product gets permission registration first in the whole world, goes on the market in Rome with Adengo trade name.Thiophene Tong Huanglongshi Beyer Co., Ltd since two thousand seven after corn field herbicide tembotrion and little grain cereal weed killer herbicide pyrasulfotole, the 3rd the new weed killer herbicide marching toward market.Thiophene ketone sulphur is grand is interior absorption medicament, by root and the leaf absorption of plant, has and tags and residual herbicidal effect, can effectively prevent and kill off corn field grassy weed and broad leaved weed, between blade face application and residual action, show good balance.
Atrazine, English name is atrazine, and chemical name is the chloro-4-ethylamino-of 2--6-isopropylamino-1,3,5-triazines.Atrazine is before selectivity inner sucting conduction type seedling, herbicide after seedling, and based on root absorption, cauline leaf absorbs seldom, is transmitted to rapidly plant meristematic tissue and leaf portion, and interference photosynthesis makes weeds lethal.In the resistance crop bodies such as corn, atrazine is resolved into innocuous substance by corn ketolase, thus to seeding corn and other crops safety.The lasting period of atrazine is longer, broad weed-killing spectrum, for preventing and kill off corn field annual weed, especially better to the preventive effect of corn field broad leaved weed.Atrazine easily by rainwater drip washing to soil comparatively deep layer, also effective to some dark root grass, but easily produce poisoning.When weeds generation density is higher, or when plant is larger, it is difficult to thoroughly kill weeds.
Find through long-term field trial and marketing application, benzene azoles humulone is used alone the preventive effect of lady's-grass and barnyard grass undesirable; The grand cost that is used alone of thiophene ketone sulphur is high, is unfavorable for spread; When atrazine is used alone, dosage is large, poor to the control efficiency of grassy weed, and has a certain impact to second stubble crop such as wheat and other broad leaf crops.Moreover, benzene azoles humulone and thiophene ketone sulphur grand composite, the control efficiency of grass family lady's-grass and barnyard grass is not reached to the effect of synergy.
