The weeding composition is mainly characterized by comprising 1 to 60 weight percent of active ingredient A and 1 to 80 weight percent of active ingredient B; and the weeding composition can be prepared into wettable powder, water-dispersible granules, a suspending agent, suspension emulsion, aqueous emulsion and microemulsion, is used for preventing and controlling weeds in corn fields and wheat fields, and has the characteristics of reducing the using amount of pesticides and pesticide residues, along with high environmental compatibility and safety for people 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 triazines, be used for control of maize field, 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 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, make the agricultural chemicals of performance complement obtain best synergistic effect through the proportioning of adjusting different agricultural chemicals.

Embodiment
The embodiment of the invention is the method that adopts indoor biological activity determination and field trial to combine.Pass through indoor biological activity determination, the E-E after clear and definite two kinds of medicaments are composite by a certain percentage earlier
0Value on this basis, is carried out field trial again.
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.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 following:
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 active component B or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
E
0During for diflufenican and active component B or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
When E is diflufenican 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 atrazine, the terbutryn.

Application implementation example three: diflufenican and atrazine, terbutryn control of maize field, wheat paddock weeds field control effectiveness test
The control medicament: diflufenican and atrazine, terbutryn complex composition, produce by the research and development of Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
Contrast medicament: 50% diflufenican wetting powder (commercial); 48% atrazine wetting powder (commercial); 50% terbutryn suspending agent (commercial).
If artificial weeding and clear water control treatment.
Method for using: convert behind 30 liters in the water evenly that cauline leaf sparges in each sub-district for every mu.
Spraying time:, the weeds in field 2-4 leaf phase, carry out cauline leaf spraying 1 time in corn, wheat 2-4 leaf phase.
Investigation method and drug effect are calculated:
Investigation weeds object: weeds such as barnyard grass grass, nutgrass flatsedge, lamb's-quarters, oat, clearvers, chickweed, investigate back 7 days, 30 days to strain preventive effect of weeds and 30 days fresh weight preventive effect.
The visual test medicament does not have poisoning to corn, wheat to be taken place.
Test of pesticide effectiveness report one
The table 3 diflufenican atrazine built composition for preventing and controlling corn field weed test of pesticide effectiveness
Can know by table 3; Diflufenican and atrazine are composite to have good control efficiency to corn field barnyard grass grass, nutgrass flatsedge, lamb's-quarters, and corn is had certain raising the output, and preventive effect is superior to single agent preventive effect; And contrast medicament, artificial weeding, with respect to significant difference between the rate of growth of clear water control treatment; And have quick-acting and lasting effect preferably, in this test scope of medication, to corn safety.Test of pesticide effectiveness report two
The table 4 diflufenican terbutryn built composition for preventing and controlling wheat paddock weeds test of pesticide effectiveness
Can know by table 4; Diflufenican and terbutryn are composite to have good control efficiency to weeds such as wheat paddock oat, clearvers, chickweeds, and wheat is had certain raising the output, and preventive effect is superior to single agent preventive effect; And contrast medicament, artificial weeding, with respect to significant difference between the rate of growth of clear water control treatment; And have quick-acting and lasting effect preferably, in this test scope of medication, to wheat safety.
