Abstract
The invention relates to a weeding composition containing diflufenican and clopyralid, which is mainly characterized by comprising 1 to 80 percent of diflufenican, 1 to 80 percent of clopyralid, an aid and other excipients, and the weeding composition can be prepared into wettable powder, aqueous dispersion granules, a suspending agent, a suspension emulsion, an aqueous emulsion and a microemulsion. The weeding composition is used for preventing and controlling weeds of wheat fields, and has the characteristics of reducing the dosage and residues of pesticides, along with high environment compatibility and safety on human and livestock.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains diflufenican and clopyralid, be used to prevent and treat the wheat paddock weeds.
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.

Embodiment
Below in conjunction with embodiment to further instruction of the present invention.
Implementation of an application example one:
Diflufenican and clopyralid are mixed to the active determination test report of wheat paddock weeds
Test objective: under the greenhouse pot culture condition, measured diflufenican and clopyralid and different blended combo thereof and closed herbicidal effect to clearvers, and estimated its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis.
For trying target: clearvers (Galium aparine L. var.tenerum).
Test medicine: diflufenican (diflufenican) 98% former medicine, clopyralid (clopyralid) 95% former medicine, agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:
Diflufenican solution: accurately take by weighing the former medicine of 0.0467g 98% diflufenican, dissolve with the 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir, be configured to diflufenican 180g (a.i.)/ha solution, again with clear water be diluted to 100,60g (a.i.)/ha concentration is standby.
Dichloropyridine acid solution: accurately take by weighing the former medicine of 0.0856g 95% clopyralid, dissolve with the 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir, be configured to clopyralid 320g (a.i.)/ha solution, again with clear water be diluted to 200,120g (a.i.)/ha concentration is standby.
Blank solution: the 1mL vegetable oil adds the water of 400mL 0.1% agricultural newborn 600#.
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 diflufenican is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
Y is a clopyralid or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
E
0During for diflufenican and clopyralid or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
When E is diflufenican and clopyralid 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, when-10%≤E-E0≤10%, be expressed as summation action, when E-E0＜-10%, be expressed as antagonism.
Table 1 diflufenican and clopyralid and the toxicity test result of combination that be mixed thereof to clearvers
Evaluating drug effect: diflufenican and clopyralid and the composition that is mixed thereof see Table 1 to the herbicidal effect measurement result of clearvers.As seen, diflufenican and clopyralid show synergistic effect to clearvers, its E-E with 60+120,60+200,60+320,100+120,100+200,100+320,180+120,180+200, the 180+320 composition that is mixed
0Value is respectively 13.02,15.77,16.58,17.57,21.58,15.46,15.24,16.03,10.08, and is wherein best to the effect of clearvers with the composition that is mixed of 100+200, its E-E
