Description

Containing triazinone herbicide and the ALS Herbicidal combinations suppressing dosage form herbicide and application thereof
Technical field
The present invention relates to a kind of method preventing and treating undesired plant growth, the method uses a kind of herbicidal composition suppressing dosage form herbicide and triazinone herbicide containing ALS.
Background technology
Undesired plant growth can cause that crop yield is greatly decreased.Therefore, will obtaining crop good harvest, preventing and treating undesired plant growth is extremely important, and to continue the noxious plant preventing and treating in farmland.
ALS suppresses dosage form herbicide to can be used to prevent and treat undesired plant growth.nullSuch as,ALS suppresses dosage form herbicide to include sulfonylurea herbicide,Such as amidosulfuron (amidosulfuron)、Azimsulfuron (azimsulfuron)、Sulfometuron Methyl (bensulfuron)、Chlorine phonetic (chlorimuron)、Ring the third cinosulfuron (cyclosulfamuron)、Ethoxysulfuron (ethoxysulfuron)、Flazasulfuron (flazasulfuron)、Flucetosulfuron (flucetosulfuron)、Fluorine pyridine sulphur grand (flupyrsulfuron)、Foramsulfuron (foramsulfuron)、Halosulfuronmethyl (halosulfuron)、Imazosulfuron (imazosulfuron)、Mesosulfuronmethyl (mesosulfuron)、Piperazine pyrazosulfuron (metazosulfuron)、Sulfonylurea (methiopyrisulfuron)、Monosulfmeturon (monosulfuron)、Nicosulfuron (nicosulfuron)、Orthosulfamuron (orthosulfamuron)、Oxasulfuron (oxasulfuron)、Primisulfuronmethyl (primisulfuron)、Promazine Sulfometuron Methyl (propyrisulfuron)、Pyrazosulfuron (pyrazosulfuron)、Rimsulfuron (rimsulfuron)、Sulfometuron Methyl (sulfometuron)、Sulfosulfuron (sulfosulfuron)、Trifloxysulfuron (trifloxysulfuron)、Azoles Sulfometuron Methyl (zuomihuanglong)、Chlorine sulphur grand (chlorsulfuron)、Cinosulfuron (cinosulfuron)、Ethametsulfuron (ethametsulfuron)、Iodine metsulfuron-methyl (iodosulfuron)、Different Ou Fen sulphur grand (iofensulfuron)、Metsulfuron-methyl (metsulfuron-methyl)、Prosulfuron (prosulfuron)、Thifensulfuronmethyl (thifensulfuron)、Triasulfuron (triasulfuron)、Tribenuron-methyl (tribenuron)、Triflusulfuronmethyl (triflusulfuron)、Tritosulfuron (tritosulfuron)、Metsulfuron-methyl (metasulfuronmethyl)、Chlorimuronethyl (chlorimuron-ethyl)、The grand free acid of sulphur (clopyrasulfuron) and sulfometuronmethyl (sulfometuron-methyl).
Above-mentioned herbicide, its production procedure, the herbicidal composition containing above-mentioned herbicide and this technical field that is applied in as herbicide thereof belong to known knowledge; such as; (thePesticideManual in Britain crop protection committee 1991 " pesticide handbook " the 9th edition; 9thedition (1991); TheBritishCropprotectionCouncil, London);Ag chemistry new product summary (AgChemNewProductReview), Ag chemical information service (AgChemInformationServices), Indianapolis (Indianapolis, Ind.) and similar document record.
But, ALS suppresses dosage form herbicide, for instance sulfonylurea herbicide, it is possible to crop is produced phytotoxicity.Helianthi is one of which to ALS suppresses the crop of dosage form herbicide sensitive, it may appear that apical bud development is slow, variable color and the symptom (Alonso-Prados etc., 2002) be completely cured.The phytotoxicity of herbicide can slow down the growth of crop, even results in it dead.Accordingly, it is desirable to a kind of plant-less toxicity or low phytotoxicity and can efficiently prevent and treat the compositions of undesired plant growth.
Surprisingly, have now found that suppressing the Herbicidal combinations of the present invention of dosage form herbicide can reduce ALS containing triazinone herbicide and ALS suppresses dosage form herbicide to crop (such as forage crop, such as Caulis Sacchari sinensis) vegetalitas toxicity, and do not reduce its preventing and treating undesired plant growth drug effect.
Summary of the invention
Therefore the present invention relates to a kind of undesired plant growth that can control and can reduce again the ALS suppression dosage form herbicide phytotoxic method to crop, the method includes using, to crop or its position, the compositions suppressing dosage form herbicide containing triazinone herbicide and ALS.
" phytotoxicity " described in the context of the invention relates to all herbicide impacts hindering crop normal development.The phytotoxicity of herbicide may suppress plant growth, even causes plant death.Therefore to keep crop healthy, then need plant-less toxicity or low phytotoxic herbicide.
The triazinone herbicide suppressing dosage form herbicide containing ALS consecutively or simultaneously can be used by any desired order and combination.Triazinone herbicide can suppress jointly using of dosage form herbicide may be accomplished by with ALS: is obtained and mix (being known as a barrel mixture, pre-mixing agent, fermentation liquid spraying or slurry mode) by independent preparation source, and can be optionally added other pesticide, such as other antibacterial, insecticide and nematicide, or obtained (being known as pre-mixing agent, concentrating agents, built agent (or product)) by monospecies preparation mixture source, and optionally it is mixed into other pesticide, for instance other antibacterial, insecticide and nematicide.
