(2) blade face permeability test
1, cucumber test
For studying object: cucumber
Reagent agent and comparison medicament: Zhongshengmycin and kasugarnycin compound (the two weight ratio is 1:5)；Jinggangmeisu
For examination synergist and control auxiliary agent: N-380；A kind of glycosyl modified organic silicon auxiliary agent of NF-100(), penetrant t
Test method:
Weigh reagent agent respectively, comparison medicament, for examination synergist and control synergist is prepared with 0.5% Tween 80 such as 1 institute of table
The various flushing liquor inorganic agents stated, each concentration for handling Chinese medicine are 400mg/L, and synergist/control auxiliary agent concentration is 100
Mg/L, the two ratio are 4:1.
Health, the consistent cucumber seedling of growing way are chosen, spraying treatment, every processing are carried out to each treatment agent using spray tower
5 plants of seedling.Each processing spray amount is consistent, and controlling is 5ml/ plants.After the completion of spraying, by seedling as ventilation, and start timing.
After 5 hours, the middle part blade of each processing seedling is taken respectively according to multi-point sampling method, with clear water cleaning blade surface
3 times, after dried with blotting paper, to remove blade surface medicament.
The blade 5g for removing surfactant is accurately weighed, is put into centrifuge tube after liquid nitrogen frozen, crushing, 10ml methanol is added
It is filtered after concussion is extracted 30 minutes with filter paper with water mixed solution (volume ratio 3:7), is then centrifuged 5 minutes for 3000 revs/min,
Supernatant is taken, with silica gel column purification, collects whole leacheates, it is close dry in being concentrated on Rotary Evaporators, with 2ml pure water constant volume,
Pesticide concentration in HPLC test sample.3 repetitions of every processing.As a result it see the table below 1.
The infiltration capacity of each treatment agent of table 1
The above results are not difficult to find out that synergist N-380 can obviously increase Zhongshengmycin and kasugarnycin compound penetrates into cucumber
The amount of blade, infiltration capacity are far longer than NF-100 and penetrant t.But synergist N-380 is to comparison medicament jinggangmeisu
Osmotic effect compared with when adding NF-100, penetrant t, do not observe notable difference.
2, rice test
For studying object: rice
The same cucumber test of remaining test method.As a result 2 be see the table below.
The infiltration capacity of each treatment agent of table 2
The above results are not difficult to find out, for rice crop, do not observe synergist N-380 compared to control auxiliary agent NF-100, infiltration
Saturating agent T permeates test medicine Zhongshengmycin and the improved blade face of kasugarnycin compound and comparison medicament jinggangmeisu
Amount namely N-380 not can increase infiltration of the drug into rice leaf.
(3) field trial
Medicament of the present invention is measured to the control efficiency of cucumber disease.Test medicine is invention formulation embodiment 1-6 medicament, control
Medicament is reference examples 1-3 medicament.Test medicine, comparison medicament and the processing of the cell of blank control are arranged using random district's groups, small
50 square metres of area's area, 4 repetitions.Application processing is investigated after 7 days using random five point sampling, as a result see the table below 3.
3 field control effect of table
Field control result is not difficult to find out that medicament of the present invention is obviously increased compared to comparison medicament, preventive effect.
Examples detailed above is only that of the invention is explained further, and is not limitation of the invention, by by above-mentioned side
Case progress simply adjusts the scheme obtained from, equally within the scope of protection of this application.
