Abstract
The invention relates to a herbicidal composition containing florasulam. The composition is mainly characterized in that the herbicidal composition comprises 1-60% of active ingredient A, 1-80% of active ingredient B and the balance of auxiliaries. The active ingredient A is florasulam while the active ingredient B is selected from mesotrione or chlortoluron. The composition can be prepared into wettable powder, water dispersible granules, suspension, suspended emulsion and the like. The herbicidal composition provided by the invention is used for preventing and treating weeds in wheat and corn fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of composition pesticide that contains florasulam, be used to prevent and treat wheat paddock and corn 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 is high; (3) selectivity is high.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, be that the agricultural chemicals of performance complement obtains best synergistic effect through the proportioning of adjusting different agricultural chemicals.

2O, chemical name: N-(3-chloro-4-aminomethyl phenyl)-N, the N-dimethyl urea, chlortoluron absorbs through 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, the dispenser inequality has poisoning slightly, and 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.Therefore, 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 are difficult to eliminate with other weed killer herbicide.
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.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, has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers about the relevant composite product of florasulam with nitre sulphur humulone, chlortoluron.

Embodiment
Below in conjunction with embodiment the present invention is further illustrated.
Practice example one:
Florasulam and active ingredient B are mixed to the active determination test report of weeds in field
Test objective: under the greenhouse pot culture condition, measured florasulam and nitre sulphur humulone or chlortoluron and different blended combo thereof and closed herbicidal effect to lamb's-quarters; And estimated its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis.
Supply the examination target: lamb's-quarters (Chenopodium album).
Test medicine: florasulam (florasulam) 97% former medicine, nitre sulphur humulone (mesotrione) 97% former medicine, chlortoluron (chlortoluron) 95% former medicine, agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:
Florasulam solution: accurately take by weighing the former medicine of 0.0039g 97% florasulam,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to florasulam 15g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 5g (a.i./hm with clear water again
2), 2g (a.i./hm
2) concentration is subsequent use.
Nitre sulphur humulone solution: accurately take by weighing the former medicine of 0.0787g 97% nitre sulphur humulone,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to nitre sulphur humulone 300g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 150g (a.i./hm with clear water again
2), 50g (a.i./hm
2) concentration is subsequent use.
Chlortoluron solution: accurately take by weighing the former medicine of 0.1338g 95% chlortoluron,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to chlortoluron 500g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 300g (a.i./hm with clear water again
2), 100g (a.i./hm
2) concentration is subsequent use.
Blank solution: 0.2mLDMF adds the clear water that contains 400mL 0.1%TWEEN80 emulsifier.
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; To supply 15～20 sowings of examination target weed seed in polypots; 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 repetition 4 times, and establish the contrast that is treated to that does not contain medicament.Handle the back examination and just place in the greenhouse in and cultivate, the growing state of routine observation target weeds, be injured symptom and growth inhibition situation of range estimation target behind the 15d, and title acrial part fresh weight or strain fresh weight are with the toxicity action of form fresh weight inhibiting rate evaluation medicament 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 following:
E
0＝X+Y-XY/100
In the formula, X is that florasulam is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that nitre sulphur humulone or chlortoluron are with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for florasulam and nitre sulphur humulone or two kinds of pharmacy mix of chlortoluron to the theoretical value of target weeds fresh weight inhibiting rate; When E is florasulam and nitre sulphur humulone or two kinds of pharmacy mix of chlortoluron 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.
