The pesticide composition, showing obvious synergistic effect on the ratio range, reduces the pesticide dosage, reduces the pesticide dosing number, reduces the pesticide dosing cost, reduces the adverse effects of pesticides on ecological environment, expands the herbicidal spectrum, can solve various weed problems by one-time use, makes up the defects and limitations when using a single agent, extends the agent service life, has the vital significance to the comprehensive treatment of weed resistance, is fast in drug efficacy, long in period of preserving effect and low in use cost, and can be used to control gramineous weeds, broadleaf weeds and sedge weeds in rice fields.
Description
Technical field
The invention belongs to technical field of pesticide, being specifically related to a kind of composition pesticide containing Stam F-34, cyhalofop-butyl and methoxone for preventing and kill off paddy field grassy weed, broad leaved weed and sedge weed.
Background technology
According to statistics world's cereal produce annual due to illness, worm, crop smothering loss 14%, the loss that wherein crop smothering causes is about 11%, and Weed infestation is the key factor of restriction crop yield.The use of chemical herbicide is one of important symbol of agricultural modernization.In recent years, the sales volume of weed killer herbicide increases year by year, and the proportion accounting for agricultural chemicals sales volume increases year by year, uses area and expands year by year.Paddy rice is the crops that Consumption of China amount is maximum, cultivated area is maximum, gross yield is maximum, per unit area yield is the highest, has consequence in the world.But the serious of rice field crop smothering is the major obstacle restricting its high yield, stable yields.At present, the pattern that preventing and kill off of weeds in paddy field adopts more " envelope, two is killed, three benefits " is carried out, there is different weed killer herbicide kinds available for different phase at present, but most kind is difficult to ensure a drug and keep paddy rice interior without grass for whole breeding time, the increase of times for spraying substantially increases cost accounting undoubtedly, has also increased the weight of the impact on environmental ecology.Therefore, exploratory development paddy field once uses and keeps seeming particularly important without the safety of grass, highy potent herbicide in paddy rice whole breeding time.
Stam F-34, chemical name: N-(3,4-dichlorophenyl) propionamide.Belonging to acetamide-group herbicides, mainly through the action of contace poison of high selectivity, is selectivity herbicide after seedling.Stam F-34 is for preventing and kill off the broad leaved weed of the Tanakas such as rice seedling bed, Honda, live field and grassy weed as barnyard grass, Monochoria vaginalis and dryland paddy lady's-grass, green foxtail etc.
Cyhalofop-butyl, chemical name: (R)-2-[4-(4-cyano group-2-fluorophenoxy) phenoxy group] butyl propionate.Belong to aromatic oxygen-phenoxy group propionates class weed killer herbicide, absorbed by plant leaf blade and leaf sheath, phloem conducts, accumulate the district of attending to anything else in plant, suppress acetyl-CoA carboxylase, fatty acid is synthesized and stops, the growth division of cell can not normally be carried out, membranous system etc., containing fat structural deterioration, finally cause Plant death.Stam F-34 effectively can be applied to and prevent and kill off important grassy weed, not only efficient to various barnyard grass, also can prevent and kill off moleplant seed, lady's-grass, green foxtail, eleusine indica, amur foxtail etc.
Methoxone, chemical name: 32-methyl-4-chlorophenoxyacetic acid.Belong to phenoxy acetic acid class weed killer herbicide, can destroy the conducting tissue of dicotyledon, making to grow is interfered, cauline leaf distortion, and basal part of stem expands thicker or ftractures.Be applicable to paddy rice, wheat and other dry crops control convexutricle sedge herb, Monochoria vaginalis, rhizoma alismatis, angustifolia arrowhead herb and other broad leaved weeds.
Summary of the invention

Embodiment 9 Stam F-34, cyhalofop-butyl and methoxone optimum proportioning screen
In order to understand Stam F-34, cyhalofop-butyl and methoxone mixture further to the synergy of weeds, the present inventor has carried out formulation screening test to Stam F-34, cyhalofop-butyl and methoxone mixture.
Test material: without awns barnyard grass (Echinochloa crusgali (L.) Beauv.var.mitis (Pursh) Peterm.Fl.), Eclipta prostrata (Ediptapro strata L.), difformed galingale herb (Cyperus difformis L.), in October, 2013 picks up from experimental field, Jiangsu Province Agriculture Science Institute, adopt natural air drying under rear room temperature condition, load paper bag, be placed in 4 DEG C ± 0.5 Refrigerator store.
Test apparatus: PWT-510 type spray tower, plum Teller AB135-S electronic balance, volumetric flask, triangular flask, beaker, graduated cylinder, polypots, pipette, chi, scissors etc.
Test method: first take the former medicine of the Stam F-34 of certain mass, cyhalofop-butyl and methoxone, add the Tween 80 aqueous solution dilution that methyl alcohol fully dissolves rear use 0.1%, be mixed with single dose mother liquor, arrange serial proportioning according to mixture object, it is stand-by that each proportioning arranges 5-7 concentration gradient.Polypots (15cm × 11cm × 7cm) is filled air-dry fine earth, in infiltrating irrigation mode bottom polypots, makes soil completely moistening.Soil be horse liver soil, pH6.7, the content of organic matter 1.6%, air-dry sieve after for subsequent use.Each polypots is broadcast without awns barnyard grass 35, Eclipta prostrata 15 respectively, difformed galingale herb 15, and broadcast rear fine earth and cover, thickness is about 0.2cm.Jiangsu Province Agriculture Science Institute 300m is put into after broadcasting rear soil spraying process
2greenhouse by solar heat is cultivated, and keep the skin wet every day maintenance ground moistening.
After medicine, routine observation is without the growing state of awns barnyard grass, Eclipta prostrata and difformed galingale herb.After medicine, investigation in 30 days is without awns barnyard grass, Eclipta prostrata and difformed galingale herb overground part fresh weight, calculates fresh weight inhibition namely to the preventive effect of target weeds.Adopt DPS data handling system to obtain the virulence regression equation of single dose Stam F-34, cyhalofop-butyl, methoxone and 15 Ternary agent, calculate ED
50value and 95% confidence limit.Co-toxicity coefficient is calculated by the abundant method of Sun Yun.Co-toxicity coefficient is greater than 120 and is expressed as synergistic effect, is less than 80 and is expressed as antagonism, be expressed as summation action between 80 ~ 120.
