Embodiment
The present invention is further illustrated in the following embodiments, and this does not limit the scope of the invention.
Toxicity determines embodiment
Kasugarnycin compounds the Toxicity Determination to rice blast fungus with epoxiconazole
Subjects：Pick up from the rice blast fungus in field
Test method：Reference≤People's Republic of China (PRC) agricultural industry criteria NY/Tll54.7 1 >=, pot-culture method.Choosing
The tri-leaf period rice seedlings that growth potential is consistent are taken, per the young plant of basin 2, each processing is from 5 basins for examination rice seedling.By Pyricularia oryzae in tomato
Cultivated on oat-agar cultures base, with spore under sterile washing after production spore, be made 1 × 105Individual spore/mL suspension, uniformly
Ground spray inoculation is inoculated with black polybag moisturizing culture 24h in rear enclosure on for examination rice seedling.After being inoculated with 24h, chemicals treatment is carried out,
Each medicament sets 5 concentration gradients, is sprayed with Potter spray towers under 50Psl pressure, per basin about 5mL., will after spray
Rice seedling is placed in 25 DEG C or so, relative humidity>Cultivate under conditions of 90%, investigated after 7d according to the morbidity grade scale of rice blast
The disease index of whole strain blade, and calculate prevention effect.
Prevention effect is converted into niqueMin (y), liquor strength (ug/ml) is converted into logarithm value (x), with least square method
Concentration EC in calculating virulence equation and suppressing50.The toxicity index and co-toxicity coefficient (CTC) of medicament are calculated according to the abundant methods of Sun Yun.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) ×100
A percentage composition+B medicament toxicity index x mixtures in theoretical toxicity index (TTI)=A medicament toxicity index × mixture
Middle B percentage composition
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI) × 100
When CTC≤80, then composition shows as Hangzhoupro effect short of money, when 80<CTC<120, then composition show as summation action,
When CTC >=120, then composition shows as synergistic effect.
Toxicity Determination result see the table below 1：
The kasugarnycin of table 1 compounds the Toxicity Determination result to rice blast fungus with epoxiconazole
Toxicity Determination result shows that kasugarnycin is matched 1 with epoxiconazole:50~50:Between 1, to rice rice blast
Germ has synergistic effect, especially 1:30~30:Between 1, for co-toxicity coefficient more than 150, synergy is more obvious.
The composition pesticide of the present invention can be prepared into any one formulation of suitable agricultural use with known method, than
Preferable formulation is wettable powder, suspending agent, water dispersible granules, aqueous emulsion and microemulsion.
