E0To the theoretical value of target weeds fresh weight inhibition for mesotrione and during two kinds of pharmacy mix of pyraclonil；
To the measured value of target weeds fresh weight inhibition when E is mesotrione and two kinds of pharmacy mix of pyraclonil.
Evaluation criterion：Work as E-E0Synergistic effect is expressed as during ＞ 10%, as -10% ＜ E-E0It is expressed as being added during ＜ 10%
Effect, works as E-E0Antagonism is expressed as during ＜ -10%.
Toxicity test result of 2 mesotriones with two kinds of medicaments of pyraclonil to moleplant seed
Table 1 is the mixing virulence measurement result of mesotrione and two kinds of medicaments of pyraclonil
Virulence test example shows, is 1 in active ingredient mesotrione and pyraclonil ratio:50~50:Showed during 1 dilution
Go out certain synergistic effect, wherein mesotrione and pyraclonil are 1:20~20:1 synergistic effect is most obvious.Result of the test
Show, mesotrione and pyraclonil Complex synergism are good in room conditions, it is proposed that to suitable proportion 1:20~20:1 is left
Right mixture preparation carries out further field control effectiveness test, to evaluate its field practical application effect.
3 field control effectiveness tests
Field control effectiveness test prevents and kill off paddy field weed
Test site is located at the bridge fore-and-aft gangway village of Fuyang City Fu Chun streets three, and rice varieties are II excellent 084, pH value 7.2, and category is flat
Original area, middle fertility, experimental field main weeds have barnyard grass, moleplant seed etc., weeding control effect is uniform.Result of the test is as follows：
The mesotrione of table 2 and pyraclonil compounding field efficiency test
Field experiment result shows that mesotrione is compounded to weeds such as rice terrace grass family, broadleaved herbs with pyraclonil
Preventive effect is preferable, is estimated according to field, and in the range of test dose, plant growth is normal, has no that plant produces poisoning and exception
Phenomenon, it is safe to rice to illustrate it.
To sum up virulence and field experiment result verification, the Herbicidal combinations of the invention containing mesotrione and pyraclonil,
It is mainly used in preventing and kill off broad leaved weed, grassy weed, and to Target crops safety, compared with single dose, Herbicidal combinations of the present invention
It is unique with the mechanism of action, have that dosage is few, weeding is general more extensively, and the lasting period is longer, the obvious advantage such as more environmentally-friendly.So
The research and development and popularization of the present invention have great social effect and environment protection significance.
