Abstract
The invention relates to a pesticide composition and especially relates to a weeding composition comprising a glyphosate weeding compound and a quinclorac salt and a preparation method thereof. The weeding composition effectively improves effects of preventing and removing worst weed.
Description
Denomination of invention
A kind of Herbicidal combinations and preparation method for controlling malignant weed
Technical field
The present invention relates to a kind of composition pesticide, specifically a kind of combination by glyphosate class herbicides compounds and dichloro quinolinic acid salt and preparation method thereof, said composition has effectively improved the preventive effect for malignant weed.
Technical background
Glyphosate (Glyphosate) belongs to organic phosphates, a kind of interior suction conduction, wide spectrum steriland herbicide, the main interior enol acetonyl shikimene phosphate synthase of plant corpus that suppresses, thereby suppress the conversion of shikimene to phenyl alanine, cruel propylhomoserin and tryptophan, the synthetic of protein is interfered, causes plant death.Glyphosate is to be transmitted to each position of plant after absorbing by cauline leaf, can prevent and kill off the plant of the sections more than 40 such as unifacial leaf and dicotyledonous, annual and perennial, herbs and shrubs.Be combined and lose activity with metal ions such as iron, aluminium very soon after glyphosate buries, seed hiding in soil and edaphon are had no adverse effects.Because glyphosate is combined and passivation with metal ions such as iron, aluminium very soon after the soil contact, lose activity, therefore, can only process as cauline leaf.
Dichloro quinolinic acid is hormone-type quinoline carboxylic acid weed killer herbicide, main by seed, root, stem and the absorption of leaf section of sprouting, and, rapidly to stem and top conductive, is the weeds death, similar to the effect symptom of auxin substance.The characteristics such as it is strong that dichloro quinolinic acid has selectivity, and the amplitude broad in dispenser period is rapid-action, and the residence time in soil is long.Barnyard grass is had to very high preventive effect, can also effectively prevent and kill off Monochoria vaginalis, Chinese celery etc.Can be for cauline leaf and soil treatment.
Because the former medicine of dichloro quinolinic acid is water insoluble, the kind of this weed killer herbicide all is prepared into wetting powder, water dispersible granules and suspending agent and applies on agricultural for a long time.Because the long-term part susceptible weeds of using has produced resistance to dichloro quinolinic acid, reduced preventive effect, therefore add that the solvability of dichloro quinolinic acid in water is low, in use inevitably can produce that dispenser is inhomogeneous, the absorption that is unfavorable for plant, take effect and wait slowly to obtain shortcoming.Along with the continuous progress of technology in recent years, developed gradually the salt series products of dichloro quinolinic acid, it has been prepared into soluble salt by insoluble dichloro quinolinic acid, thereby can be prepared into easily the novel forms such as water solube powder, water-soluble granule.The former medicine of water-soluble dichloro quinolinic acid is easier to be mixed with other weed killer herbicides, obtains larger herbicide spectrum, improves the Absorption of medicine on the weeds blade face, thereby significantly shortens responding time, improves the herbicidal effect of dichloroquinoline acid supplement.
As previously mentioned, due to the glyphosate broad weed-killing spectrum, can effectively kill most weeds, deeply be subject to liking of users, glyphosate has become one of weed killer herbicide of global consumption maximum, also just because of this, and along with the extensive use of glyphosate, add that peasant's dispenser is unreasonable, accelerated the generation of resistance glyphosate weeds.The weeds that develop immunity to drugs to glyphosate in the whole world at present have long awns amaranth, tool knurl amaranth, junglerice, Paspalum conjugatum, eleusine indica, Horseweed Herb, wild pool wormwood artemisia, artemisiifolia, three row artemisiifolias, wimmera ryegrass, Annual Ryegrass, rib grass, painted euphorbia, false Chinese sorghum, class broomcorn millet tail bran grass etc.Except resistant weed, also have the more difficult weeds of preventing and kill off of some glyphosates, as perennial weeds such as meadow pine, corn sow thistle, field thistle, Ji, welted thistle.
Chinese patent application 99809621.0 discloses the Herbicidal combinations for tolerance or resistant rice crops, be mainly used in the noxious plant of controlling in the tolerant rice crop, although disclose the combination of glyphosate (salt) and two chloroquine phosphoric acid in this patent, but the embodiment that does not provide both to combine and definite drug effect data, and it is mainly used for killing the conventional weeds of transgenic rice paddy Crop Species.
