Abstract
The invention belongs to the field of pesticides, and particularly relates to a beet herbicide. The beet herbicide provided by the invention contains active ingredients such as isoxaflutole and oxadiargyl which are blended with each other without conflict; a herbicide controlling spectrum is wide, so that most of annual and perennial weeds can be prevented and killed, weeds coming out of the ground can be effectively killed, weeds which do not come out of the ground can also be controlled, and the weeding effect is improved; a good synergistic effect is achieved when the active ingredients in the herbicide provided by the invention are matched in a certain range, the prevention effect is higher than that of a single herbicide, and the drug property maintaining time is long; and the beet herbicide can be used before and after emergence of seedlings, the using period is flexible, and the safety is good.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of beet weed killer herbicide.
Background technology
Isoxaflutole,
, sterling is canescence or light yellow solid; Fusing point 140 DEG C; Density 1.590 (20 DEG C); Vapour pressure is 1 × 10-5Pa (25 DEG C).Distribution coefficient LogP=2.32; In water, solvability is 6.2 mg/l (pH 5.5 20 DEG C); Stablize light, heat storage at 54 DEG C and decompose for 14 days, in the aqueous solution of p H 1, the half life period is 1 day.
Rat acute per os L D50:>5000mg/kg; Rabbit is acute through skin L D50:>2000mg/kg; This product has minimal irritation to lagophthalmos eyeball, non-stimulated to rabbit skin.Rat acute sucks L C50 (4 hours): >5.3mg/l.Wild duck and quail acute oral L D50 (14 days): >2150mg/kg.Without mutagenicity, without teratogenesis.
Its action character is before having the activity of weeding of wide spectrum, seedling and Miao Houjun can use, weeds are dead after there is albefaction.Though the effect symptom fairly similar of its symptom and carotenoid biostatic agent, its chemical constitution feature such as polarity and degree of ionization have significantly different from known carotenoid biostatic agent etc.By suppressing the synthesis of p-hydroxybenzene pyruvate dual oxide enzyme, cause the accumulation of tyrosine, the biosynthesis of plastoquinone and vitamin e is obstructed, and then has influence on the biosynthesis of carotenoid, therefore H P P D inhibitor is similar to the effect symptom of carotenoid biostatic agent.Be mainly used in preventing and kill off grassy weed as lady's-grass, barnyard grass, knucklegrass, millet, faber bristlegrass herb, green foxtail etc. with broad leaved weed as piemarker.Amaranthus retroflexus, american ragweed, lamb's-quarters, Mandala.Guest continent knotweed, black nightshade, lady's thumb etc.
Oxadiargyl,
, sterling is white or cream-coloured powdery solid; Fusing point 131 DEG C; Vapour pressure is 2.5 × 10-5Pa (25 DEG C).Distribution coefficient LogP=3.95; In water, solvability is 0.37mg/l (20 DEG C); Photostability, adds heat-storage 54 DEG C, within 15 days, stablizes.
Rat acute per os L D50:>5000mg/kg; Rabbit is acute through skin L D50:<2000mg/kg; This product is non-stimulated to rabbit skin, has minimal irritation to lagophthalmos eyeball.Rat acute sucks L C5050 (4 hours, nose): >5.16mg/l air.Quail acute oral L D50:>2000mg/kg; To fish and water flea nontoxic.Without mutagenicity, without teratogenesis.
Be mainly used in preventing and kill off broad leaved weed as piemarker, beggar-ticks, Chenopodium weeds, Siberian cocklebur, dawrf mallow, Monochoria vaginalis, Polygonum weeds, plum blossom algae, black nightshade, common sow thistle, mexicana etc.; Grassy weed such as barnyard grass, moleplant seed, tribulus terrestris grass, Lan Macao, lady's-grass, eleusine indica, millet belong to weeds etc.; And sedge weed etc.To malignant weed four Ye Ping etc., there is good preventive effect.
At present, in beet planting process, herbicide effects used is not good, and the control efficiency especially for weeds of not being unearthed is poor, and inadequate for the safety of beet.
Summary of the invention
The invention provides a kind of beet weed killer herbicide.In weed killer herbicide of the present invention, effective active composition isoxaflutole, the mutual mixture of oxadiargyl can not produce conflict; Broad weed-killing spectrum, can prevent and kill off most of annual and perennial weed, not only effectively kills the weeds after being unearthed, also can control weeds of not being unearthed, and improves herbicidal effect; Active ingredient in weed killer herbicide of the present invention coordinates good synergistic effect within the specific limits, and preventive effect is higher than single dose, and the property of medicine is held time length; All can use before seedling and after seedling, the use age is flexible, and safety is good.
