Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains nicosulfuron, 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 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.

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.
In recent years; People are frequent to be used and has concurrently to the safety of useful crop with to the so-called selective herbicide of the herbicidal effect of undesired plants; Even but have the weed killer herbicide of high selectivity; Because of various conditions such as the kind of meteorological condition, soil condition, crop, chemicals treatment periods, also produce poisoning sometimes in use.People are studying the use of the various poisoning palliatives of the such state of affairs of not expecting of reply.At present, China also comparatively payes attention to using with aspect the research of weed killer herbicide, is extensively thought one of important measures that weed killer herbicide rationally uses, and 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 with the relevant composite product of lorox, pendimethalin about nicosulfuron.

Lorox solution: accurately take by weighing the former medicine of 0.262g97% lorox; With the 0.2mLDMF dissolving, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir; Be configured to lorox 1000g a.i./ha solution, again with clear water be diluted to 750,500g a.i./ha concentration is subsequent use.
Pendimethalin solution: accurately take by weighing the former medicine of 0.1873g95% pendimethalin; With the 0.2mLDMF dissolving, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir; Be configured to pendimethalin 700g a.i./ha solution, again with clear water be diluted to 500,300g a.i./ha concentration is subsequent use.
Blank solution: 0.2mLDMF adds the water of 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 1～3 leaf phase 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 back examination material and 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 claim acrial part fresh weight or strain fresh weight, 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 nicosulfuron is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that lorox or pendimethalin are with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for a kind of two kinds of pharmacy mix in nicosulfuron and lorox, the pendimethalin to the theoretical value of target weeds fresh weight inhibiting rate; When E is a kind of two kinds of pharmacy mix in nicosulfuron and lorox, the pendimethalin 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.

Contrast medicament: 40 grams per liter nicosulfuron dispersibility oil-suspending agents (commercial);
330 grams per liter pendimethalin missible oil (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 field annual weed 1-3 leaf phase, carry out cauline leaf spraying 1 time in the corn 4-6 leaf phase.
Dispenser place: Qianyang County, Baoji, Shaanxi province city
Investigation method and drug effect are calculated
Investigation weeds object is: weeds such as barnyard grass grass, lamb's-quarters, lady's-grass, investigate back 7 days, 25 days to strain preventive effect of weeds and 25 days fresh weight preventive effect.
The visual test medicament does not have poisoning to corn to be taken place.
Result of the test is seen table 10 respectively with analysis.
The table 10 nicosulfuron pendimethalin control of maize field weed test of pesticide effectiveness
The table 10 nicosulfuron pendimethalin built composition for preventing and controlling corn field weed test of pesticide effectiveness
Can know nicosulfuron and pendimethalin is composite that weeds such as corn field barnyard grass grass, lamb's-quarters, lady's-grass are had good control efficiency by table 10; 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 experimental drug scope, to corn safety.
