Abstract
The invention relates to mixed herbicide applying to wheat seedling and belongs to pesticide technology field. The technical point of invention lies in material component mass percent: fluoroglycofen-ethyl 5-49, fenoxaprop-ethyl 5-40, synergist 4-20, safety agent 2-20, emulsifier 2-10, cosolvent 3-10, adding solvent to 100. The inventive herbicide has obvious effect on weed killing, apparently superior to the two single agent, also apparently superior to other mixture. At same time, the inventive herbicide has a broad weed killing spectrum, can effectively prevent and kill annual Gramineae weeds and annual broad-leaved weeds. In addition, the inventive herbicide has broad application period, can be applied after wheat seedling two leaf period and before leaf period of jointing stage. The inventive herbicide has moderate residual life, can prevent and kill whole growth duration weeds per application, and have no influence on the following crops. It is an ideal herbicide for the present.
Description
Technical field: the present invention relates to a kind of weed killer herbicide that is used for the crops field, particularly a kind of mixed herbicide of wheat after seedling.
Background technology: wheat is one of staple food crop of northern China, also is important forage crop.Its long-term cultivated area reaches more than 3,000 ten thousand hectares, is only second to paddy rice.China's wheatland crop smothering area accounts for more than 30% of wheat planting area, and wherein serious injured area reaches 8%, and the general underproduction can be had no harvest when serious more than 15%.Therefore, domestic wheat uses the area of weed killer herbicide to reach 100%, and its dosage is very big.At present, the medicament of cauline leaf processing usefulness mainly contains behind the domestic wheat paddock seedling: tribenuron-methyl, thifensulfuron methyl, dicamba, metsulfuron-methyl, galloping horse, diclofop-methyl etc., its use is single agent, or anti-grassy weed, or anti-broad leaved weed.Because use for many years, weeds are developed immunity to drugs, cause its consumption to increase, make wheat produce recessive poisoning and the underproduction, and dangerous to succession crop.Simultaneously, along with the use of chemical herbicide, variation has taken place in its weed control, and is former in grassy weed as the north, now developed into the coexistence of grass family and broad leaved weed; South is former in broad leaved weed, has now developed into the coexistence of broad-leaved and grassy weed.So just press for and can prevent and kill off the wheat paddock grassy weed, can prevent and kill off broad leaved weed again, can broadcast soil treatment before the seedling of back, again can seedling after cauline leaf handle and do not influence the weed killer herbicide of succession crop.Yet this weed killer herbicide is not found at home as yet.
Summary of the invention: technical problem to be solved by this invention is: provide a kind of and can prevent and kill off the wheat paddock grassy weed, can prevent and kill off broad leaved weed again, and do not have the mixed herbicide of wheat after seedling of influence to wheat safety, to succession crop.Its technical scheme is: a kind of mixed herbicide of wheat after seedling is characterized in that its raw material components mass percent is:
Fluoroglycofen-ethyl 5-49
FenoxapropPethyl 5-40
Synergist 4-20
Safener 4-20
Emulsifier 2-10
Cosolvent 3-10
Solvent supplies 100
Above-mentioned solvent is toluene, dimethylbenzene, purified petroleum benzin, crude benzol, heavily plants benzene, light diesel fuel benzene aromatic hydrocarbons, chain hydrocarbon etc.
Above-mentioned emulsifier is the compound of anionic, nonionic and them, can be turkey red oil, diglycerol sodium laurate, castor oil polyoxy ethyl ether, the poly-ethyl ether of alkyl phenyl, aliphatic alcohol sulfate etc.
Above-mentioned cosolvent is urea, trace element, carrene, cyclohexanone, DMF etc.
Above-mentioned safener is fenchlorazole, cloquitocet_mexyl etc.
Above-mentioned synergist is azone, permeable synergistic agent, N-ethanol based dodecylphenyl sodium sulfonate, bleeding agent CN etc.
Its technique effect is: weed killer herbicide of the present invention shows by the field control effectiveness test for many years on ground such as the Inner Mongol, Liaoning, Hebei, Anhui, Shandong, Henan, in the wheat 3-5 leaf phase, weeds 1-6 leaf does not wait the phase, utilize weed killer herbicide 70,80 of the present invention, 100ml/mu, converting water sprays for 40 kilograms/mu, 7, range estimation wheat safety of 10,15,20,30 days and maturing stage and weeds preventive effect, surveyed all preventive effects, result such as following table in 15,30 days:
By range estimation, wheat is not seen symptom of chemical damage from the dispenser to the maturing stage, to wheat safety.The preventive effect of weeds reached more than 90% in 15 days, reached more than 95% in 30 days, strengthened with consumption, and preventive effect changes little, and 70-100ml/mu can reach and prevent and treat purpose, and its herbicidal effect is remarkable, obviously is better than two kinds of single agent, also obviously is better than the herbicidal effect of other mixture.Simultaneously, this weed killer herbicide weeding spectrum width can effectively be prevented and kill off annual broadleaf weeds such as annual gramineous weed such as amur foxtail, wild oat, hard grass and descurainia sophia (l.) webb ex prantl, clearvers, chickweed, Veronica, wartwort, oriental dodartia herb, benbie.In addition, it is wide that it uses period, can be used for 2 leaves-jointing frontal lobe phase behind the seedling of wheat; And its longevity of residure is moderate, and a dispenser can be prevented and kill off the weeds in the crop whole growing, and second stubble crop is not had influence, is present a kind of weed killer herbicide satisfactory for result.
Embodiment:
Embodiment 1.10 kilograms of fluoroglycofen-ethyls, 30 kilograms of fenoxapropPethyls, 5 kilograms of azones, 12 kilograms of fenchlorazoles, 10 kilograms of diglycerol sodium laurates, 10 kilograms in urea, toluene are supplied 100 kilograms.Make missible oil through mixing, filtering.
Embodiment 2.25 kilograms of fluoroglycofen-ethyls, 20 kilograms of fenoxapropPethyls, 10 kilograms of permeable synergistic agent, 8 kilograms of cloquitocet_mexyls, 6 kilograms of castor oil polyoxy ethyl ethers, 6 kilograms of carrene, crude benzol are supplied 100 kilograms.Make missible oil through mixing, filtering.
