Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of composition pesticide that contains rimsulfuron, be used for the control of maize field weed.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active height; (3) selectivity height.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, make the agricultural chemicals of performance complement obtain best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Rimsulfuron (rimsulfuron), molecular formula: C
14H
17N
5O
7S
2, chemical name: 1-(4,6-SDM-2-yl)-3-(3-ethyl sulfenyl-2-pyridine radicals sulfenyl) urea.Rimsulfuron is the sulfonylurea herbicide kind of du pont company exploitation, has advantages such as high selectivity, efficient, low toxicity, is a kind of important corn field herbicide.This medicine is the amino acid compound inhibitor, thereby by suppressing the necessary valine and the biosynthesis of isoleucine cell differentiation and plant growing is stopped.Absorb by the root leaf, conduct to meristematic tissue very soon.This medicine can effectively be prevented and kill off great majority and perennial weed in the corn field, also can be used for potato and tomato Tanaka.
Sulphur humulone (sulcotrione), molecular formula: C
14H
13ClO
5S, chemical name: 2-(2-chloro-4-methylsulfonyl benzoyl cyclohexane-1,3-diketone.The sulphur humulone is a kind of ketone weed killer herbicide that is used to prevent and kill off corn field broad leaved weed and grassy weed.Its effect characteristics are that the weeds young root absorbs conduction and works, two oxidasic synthetic by suppressing the p-hydroxybenzene pyruvate, cause the accumulation of tyrosine, the biosynthesis of plastoquinone and vitamin e is obstructed, and then having influence on the biosynthesis of carotenoid, weeds occur after the albefaction dead.
Chlortoluron (chlortoluron), molecular formula: C
10H
13ClN
2O, chemical name: N-(3-chloro-4-aminomethyl phenyl)-N, N-dimethyl urea.Chlortoluron absorbs by the root system of plant, and the blade face action of contace poison is arranged, and is the photosynthesis of plant electron transfer inhibitor.Effective to multiple grass family and broad leaved weed, to basic securitys such as wheat, barley, highland barleys, drug effect is subjected to factor affecting such as temperature, soil moisture, illumination bigger.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.They kill careless ability and scope is also different, it is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that other weed killer herbicide is difficult to eliminate.Therefore, the composite important directions that also becomes domestic and international research new herbicides of using with of weed killer herbicide, China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, work out a series of Herbicidal compositions, obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of sulphur humulone, chlortoluron about rimsulfuron.

(2) prolong the optimum period for applying fertilizer, reduce poisoning, reduce residual activity, delay drug-fast generation of weed killer herbicide and development;
(3) remarkably productive to weeds such as the nutgrass flatsedge of corn field, barnyard grass grass, wild oat, moleplant seed, lady's-grass, green foxtail, eleusine indica, amur foxtail, annual bluegrass, knucklegrass, piemarker, slim amaranth, lamb's-quarters, chickweed, clearvers, Asiatic plantain, Amaranthus retroflexus, kitchen garden, Matricaria, pale persicaria, descurainia sophia (l.) webb ex prantl, field thistles.
Embodiment
The embodiment of the invention is the method that adopts indoor biological activity determination and field trial to combine.By indoor biological activity determination, the E-E0 value after clear and definite two kinds of medicaments are composite by a certain percentage on this basis, is carried out field trial more earlier.
Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): the amount of setting soil in the polypots of high 6cm, diameter 9cm, will be in polypots for 15～20 sowings of examination target weed seed, be placed on cultivation in the greenhouse after covering the thick fine earth of 0.5～1cm, treat that weeds grew to for 2～4 leaf phases and carry out cauline leaf spraying processing, every alms bowl spraying liquid 1mL, every processing repeats 4 times, and establishes the contrast that is treated to that does not contain medicament.Processing is placed in the greenhouse cultivates, the growing state of routine observation target weeds, and be injured symptom and growth inhibition situation of range estimation target behind the 15d, and claim acrial part fresh weight or strain fresh weight, estimate the toxicity action of medicament with form fresh weight inhibiting rate to the target weeds.
Investigation method:
Range estimation target be injured symptom and growth inhibition situation are handled behind the 15d in test, and claim to calculate fresh weight inhibiting rate (%) by the acrial part fresh weight.
The synergy evaluation method:
Estimate weed killer herbicide synergy mode (NY/T 1155.7-2006) according to the Gowing method, its formula is as follows:
E
0＝X+Y-XY/100
In the formula, X is that rimsulfuron is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
Y is active component B or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
E
0During for rimsulfuron and active component B or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
When E is rimsulfuron and active component B or two kinds of pharmacy mix to the measured value of target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E-E
0Be expressed as synergistic effect at＞10% o'clock, as-10%≤E-E
0Be expressed as summation action, and worked as E-E in≤10% o'clock
0Be expressed as antagonism at＜-10% o'clock.
In the formula: active component B is selected from following any one compound, a kind of in sulphur humulone, the chlortoluron.
