Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations containing diflufenican and sulfonylurea, for preventing and treating wheat 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 ", (1) is safe, and this not only requires toxicity low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current 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 effectively approach, make the agricultural chemicals of performance complement obtain best synergistic effect by adjusting the proportioning of different agricultural chemicals.

Embodiment
The embodiment of the present invention is the method that adopts indoor biological activity determination and field trial to combine.First by indoor biological activity determination, the E-E after clear and definite two kinds of medicaments are composite by a certain percentage
0value, on this basis, then carries out field trial.
Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): at the in-built quantitative soil of polypots of high 6cm, diameter 9cm, will be for 15～20 sowings of examination target weed seed in polypots, after covering the fine earth that 0.5～1cm is thick, be placed on cultivation in greenhouse, 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 not contrast that is treated to containing medicament.Processing is placed in greenhouse cultivates, and the growing state of routine observation target weeds is estimated target be injured symptom and growth inhibition situation, and claimed acrial part fresh weight or strain fresh weight after 15d, evaluate the toxicity action of medicament to target weeds with form fresh weight inhibiting rate.
Investigation method:
Test is processed and is estimated target be injured symptom and growth inhibition situation after 15d, and claims acrial part fresh weight, calculates fresh weight inhibiting rate (%).
Synergy evaluation method:
Evaluate weed killer herbicide mode of application (NY/T 1155.7-2006) according to Gowing method, its formula is as follows:
E
0＝X+Y-XY/100
In formula, X is diflufenican fresh weight inhibiting rate to target weeds when alone with certain dosage;
Y is active component B or the fresh weight inhibiting rate to target weeds when alone with certain dosage;
E
0theoretical value to target weeds fresh weight inhibiting rate during for diflufenican and active component B or two kinds of pharmacy mix;
Measured value to target weeds fresh weight inhibiting rate when E is diflufenican and active component B or two kinds of pharmacy mix.
Evaluation criterion: work as E-E
0when > 10%, be expressed as synergistic effect, as-10%≤E-E
0≤ 10% time, be expressed as summation action, work as E-E
0when <-10%, be expressed as antagonism.
In formula: active component B is selected from following any one compound, chlorine sulphur is grand, one in AC322140, amidosulfuron.
