Abstract
The present invention relates to a composite weed killer. The present invention is prepared from bensulfuron-methyl and one of dicamba and methoxone by mixture, wherein the weight ratio of the bensulfuron-methyl to dicamba is 1: (0.2 to 40); the weight ratio of the bensulfuron-methyl to methoxone is 1: (2 to 1000); in use, the dosage of the bensulfuron-methyl is 0.5 to 5 g/mu; the dosage of the dicamba is 1 to 20 g/mu, or the dosage of the methoxone is 10 to 50 g/mu. The present invention can effectively prevent and kill various broadleaf weeds and sedge family weeds, the present invention has the functions of soil treatment and stem leaf treatment, and the prevention effect reaches more than 90%.
Description
Technical field
The present invention relates to the used weed killer herbicide of agricultural, especially for rice field, cornfield herbicidal.
Background technology
At present, the weed killer herbicide that is used for rice field, wheatland is more, acts on paddy field weeding or cornfield herbicidal but mostly be single greatly, and mostly is not before weeds grow as yet and uses, and the kind of killing grass is single.For example, patent of invention " Herbicidal combinations " (application number: 96109543.1) it is mainly Bensulfuron-methyl and acetochlor composition, but only is used for the disposable herbicide of transplanting rice field, and for the broad leaved weed that the rice field has grown, the weeding function of sedge weed is relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of compound herbicide that is used for rice field, wheatland, it can prevent and kill off multiple broadleaved herb and nutgrass flatsedge effectively, has the effect that soil treatment and cauline leaf are handled.
Technical scheme of the present invention is: it is mainly by bensulfuron-methyl and Dicamba complexing agent, and the weight ratio of bensulfuron-methyl and Dicamba is 1: 0.2-40.Its using method is when bensulfuron-methyl and Dicamba compound tense, bensulfuron-methyl 0.5-5 gram/mu, Dicamba 1-20 gram/mu.
Above-mentioned compound herbicide adopts conventional method processing usually, can be mixed into pulvis with inserts by machining, mixes chemical fertilizer or fine earth spreads fertilizer over the fields the field; Convert water dilution even spraying farmland after also can being processed into aqueous emulsion or other formulation.Compound herbicide of the present invention can be brought into play the effect of medicament soil treatment and cauline leaf processing, having avoided can only soil treatment or the single effect handled of cauline leaf, can prevent and kill off multiple broadleaved herb and nutgrass flatsedges such as Monochoria vaginalis, short arrowhead, false loosestrife, alkali grass, Herba Cyperi Glomerati effectively for the rice field; Can prevent and kill off multiple broadleaved herbs such as Herba Galii Teneri, all threads, rice cauliflower, shepherd's purse, Carolina Cranesbill Herb effectively for wheatland, overall preventive effect reaches more than 90%.
Embodiment
The present invention is further illustrated below in conjunction with embodiment:
Embodiment 1:
Take by weighing bensulfuron-methyl 5 grams, Dicamba 1 gram, bensulfuron-methyl: Dicamba=1: 0.2, add agricultural chemicals and stir the back for the powder-type weed killer herbicide with inserts (clay after the pulverizing or kaolin) 90 grams, admix again in the chemical fertilizer, spread rice field or wheatland to 1 mu; Or do not add inserts and be mixed with aqueous emulsion and after water dilution, spray to rice field or wheatland; Also can be made into other formulations, as colloidal suspending agent etc.Its function is weeds can not be grown as the soil treatment in when sowing, also can be used as the function that imposes weeding after weeds generate.
Embodiment 2:
Take by weighing bensulfuron-methyl 0.5 gram, Dicamba 20 grams, bensulfuron-methyl: Dicamba=1: 40, except that above-mentioned batching, proportioning and embodiment 1 were different, all the other were with embodiment 1.
The present invention can prevent and kill off multiple broad leaved weed and nutgrass flatsedges such as rice field, wheatland effectively, and preventive effect reaches more than 90%, has to enlarge to kill the grass spectrum, and easy to use, cost is lower, to advantages such as crop safeties.
Claims (2)
1, a kind of compound herbicide is characterized in that: mainly compound by bensulfuron-methyl and Dicamba, wherein the weight ratio of bensulfuron-methyl and Dicamba is 1: 0.2-40.
2, the using method of compound herbicide according to claim 1 is characterized in that: bensulfuron-methyl 0.5-5 gram/mu, Dicamba 1-20 gram/mu.
