Abstract
The invention discloses a herbicide composition, which is characterized by containing two active ingredients, namely cyhalofop-butyl ((R)-2-[4(4-cyano-2-fluorophenoxy) phenoxy]-butyl propionate and fluroxypyr-mepthyl (4-amino-3.5-dichloro-6-fluoro-pyridine-2-oxyacetic acid isooctyl ester); and a composition preparation for preventing and removing weeds of paddy fields can be prepared from the cyhalofop-butyl and the fluroxypyr-mepthyl with effective dose, solid or liquid carrier, auxiliary agent and other additive by a conventional method. The composition using the cyhalofop-butyl and the fluroxypyr-mepthyl has remarkable additive action, and can synthesize the combined action type, weeding activities and economic costs of the two agents by compounding the cyhalofop-butyl and the fluroxypyr-mepthyl.

Herbicidal composition of the present invention can be used for preventing and treating paddy field weed.
Herbicidal composition of the present invention includes cyhalofop-butyl (Cyhalofop-butyl) and two kinds of active components of the different monooctyl ester of fluroxypyr (Fluroxypyr-mepthyl).The mechanism of action of two kinds of medicaments has bigger difference, after cyhalofop-butyl and the different monooctyl ester of fluroxypyr are mixed, shows summation action.Can enlarge and kill the grass spectrum, reach the purpose of effective control weeds in paddy field, reduce the using dosage of medicament simultaneously, save Financial cost, reduce the pollution of medicament, and improve control efficiency important weeds to environment in the field.
Embodiment
In order to make technological means of the present invention, character of innovation, to reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention, but the present invention is not limited only to these examples.
For realizing that purpose of the present invention studies composition active component proportioning, the composition effect evaluation method is tested with the activity of weeding of Gowing method after to two kinds of herbicide mixtures.
The calculation of effect that is mixed formula is: E
0=X+Y-XY/100
In the formula: the weeds preventive effect of weed killer herbicide A when X represents that consumption is P;
The weeds preventive effect of weed killer herbicide B when Y represents that consumption is Q;
E
0The theoretical preventive effect of weed killer herbicide A+B when the expression consumption is P+Q.
Press the Gowing method, work as E-E
0, illustrate that mixture herbicide produces synergistic effect at＞10% o'clock; Work as E-E
0, illustrate that mixture herbicide produces antagonism at＜-10% o'clock; Work as E-E
0Between ± 10% o'clock, illustrate that mixture herbicide produces summation action, wherein E represents the actual measurement preventive effect % that each is handled.
Embodiment 1: the activity of herbicidal composition
Adopt the greenhouse pot culture method, the research cyhalofop-butyl is used the activity of weeding of back to direct sowing rice field main weeds barnyard grass grass, Eclipta prostrata, difformed galingale herb and moleplant seed with the different proportionings of the different monooctyl ester of fluroxypyr, the results are shown in Table 1,2.
The different monooctyl ester of table 1 cyhalofop-butyl and fluroxypyr is mixed to the control efficiency (%) of weeds
The different monooctyl ester of table 2 cyhalofop-butyl and fluroxypyr is mixed to the synergy type of weeds
The result shows: the activity of weeding after the different monooctyl ester medicament of cyhalofop-butyl and fluroxypyr is mixed is higher.Activity of weeding to barnyard grass grass, Eclipta prostrata and moleplant seed behind two pharmacy mix is very high, and is invalid to difformed galingale herb.The analysis of The combined type of action finds that all proportionings are handled 4 kinds of synergy types for the examination weeds are summation action.Consider synergy type, activity of weeding and the Financial cost of two kinds of pharmacy mix, the best proportioning of cyhalofop-butyl and the different monooctyl ester of fluroxypyr is a cyhalofop-butyl: the different monooctyl ester of fluroxypyr=1～2: 4.
