Above-described embodiment and comparative example are used for the experiment of celery root knot nematode control.
1st, test process：Experiment is carried out with reference to People's Republic of China's standard (pesticide field efficacy medicine test criterion).This examination
Test dosing and three concentration for the treatment of are set according to the difference of each composition respectively.
2nd, test method：For studying thing for celery, each plot area is 50m2, it is repeated 4 times, medicament is spreaded manuer in holes, medicine
Check that drug effect method is afterwards：Taken a little per cell diagonal, every is extracted 10 plants of investigation.Result of the test see the table below：
Prevention effect of the reagent agent of table 10 to celery root-knot nematode
The field efficacy result of table 10 shows that emamectin benzoate is obvious with iprodione synergistic effect, to celery root-knot nematode
Prevention effect be better than single dose kind and comparative example.Inventor has found that emamectin benzoate and iprodione press 1 by test：60-
60：Other ratios in 1 are compounded, and have similar prevention effect to celery root-knot nematode.
When carrying out prevention effect contrast, inventor uses other kinds of insecticide and iprodione, tests its right
The prevention effect of celery root-knot nematode.Under identical ratio, it is found that the prevention effect of emamectin benzoate and iprodione is significantly excellent
In the prevention effect of other insecticides and iprodione.Because length is limited, only listed in comparative example most representative
Insecticide fosthiazate, AVM and iprodione compounded, with illustrate emamectin benzoate and iprodione prevention effect show
Write the compounding better than other insecticides and iprodione.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
