1 synergy of test example detection
In order to further appreciate that the Herbicidal composition for paddy fields of clefoxidim and bispyribac-sodium of the invention, in standing grain in rice field
The synergy of undergraduate course weeds.Fresh weight synergy raw test has been done to rice field semen euphorbiae with example 1-7 below.
Using the clefoxidim (A) and bispyribac-sodium (B) preparation in embodiment 1-7, its co-toxicity coefficient to semen euphorbiae is measured.
Test method: the seed of quantitative semen euphorbiae is seeded in the disposable basin alms bowl of bore 8cm, depth 7cm respectively, is sowed in every basin
10~15 seeds, are cultivated in weather culturing room, and when 2~4 leaf phase of semen euphorbiae, spraying place is carried out on walking spray tower
Reason.Weather culturing room continues to cultivate after processing, and routine observation respectively handles the preventive effect to weeds, after each processing is weighed after 30d
Weeds fresh weight, by the nineteen sixties such as Sun Yunpei propose method, calculate co-toxicity coefficient.
Theoretical toxicity index TTI=standard agent toxicity index × standard agent percentage+confession in mixing assembles
Try medicament toxicity index × reagent agent percentage in mixing assembles
Co-toxicity coefficient is greater than 120, shows that two kinds of active principles have synergistic effect, co-toxicity coefficient is between 80-120, table
Bright two kinds of active principles are summation action, and co-toxicity coefficient shows that two kinds of active principles have antagonism less than 80.Measurement result
As shown in table 1.
Table 1 is to semen euphorbiae virulence test data
As can be seen from the above table, the co-toxicity coefficient after two kinds of active principle compoundings is both greater than 120, and it is bright to illustrate that the present invention has
Aobvious synergistic effect.
2 control effect testing of test example
Using embodiment 1-7 Herbicidal composition for paddy fields, 20% clefoxidim missible oil (BASF), 10% bispyribac-sodium suspending agent
(Mei Feng Agricultural Co., Ltd) has carried out the efficiency test of antagonism barnyard grass.
2 antagonism barnyard grass preventive effect data of table
The present invention a kind of pair of crop safety height produced, environmentally friendly, good drug efficacy Herbicidal composition for paddy fields-ring
The Herbicidal composition for paddy fields of methoxyphenone and bispyribac-sodium.The existing domestic product compounded without corresponding clefoxidim and bispyribac-sodium, this hair
It is bright the two to be re-dubbed the Herbicidal composition for paddy fields of environmental protection not only widened degrass spectrum also reduces and is made into the cost of single dose respectively,
Environmentally friendly, from table 2, herbicidal effect of the present invention is good, and the present invention has good environmental benefit and economic benefit.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
