Set by geometric progression in the range of 5%~90%）.If blank, it is repeated 4 times.Using pot-culture method, liquid is uniformly sprayed in
Blade face, after standby after liquid natural air drying.Spore suspension spray inoculation is used, incubator is then moved to（Relative humidity 95% with
On, 20~22 DEG C of temperature）24h is cultivated under dark condition, then temperature be 20~25 DEG C, 12h alternation of light and darkness, relative humidity
7d is cultivated under conditions of 80%~90%.When blank disease leaf rate reaches more than 50%, incidence is managed in classification investigation everywhere,
30 leaves of often treatment investigation.According to survey data, the disease index and prevention effect of each treatment are calculated.By preventive effect niqueMin and
Linear regression analysis between the logarithm value of series concentration, obtains the EC of each medicament50Value.
The co-toxicity coefficient of mixture is calculated with the abundant methods of Sun Yun（CTC）, activity of the reagent agent to germ is evaluated with this.Compounding
The co-toxicity coefficient of preparation（CTC）>=120 show as synergistic effect；CTC≤80 show as antagonism；80 ＜ CTC ＜ 120 are showed
It is summation action.
The fluopyram of table 1 is with Pyrimethanil compositional to gray mold of cucumber Toxicity Determination
Toxicity Determination result shows：Fluopyram and pyrimethanil with weight ratio be 1：80~60：1 is mixed to cucumber grey mold
It is 1 that disease has synergistic function, especially weight ratio：60~40：1 synergistic effect is especially pronounced.
, the synergy of leaf mold and spot defoliation determined.
Subjects are Fulvia fulva（Fulvia fulva）, Alternaria mali（Alternaria mali
）.The test medicine that active compound is configured to need, test method reference《Farm-chemical indoor determination test rule bactericide the 6th
Part：The synergy of mixture is determined》.Single dose and each Mixed Pharmacy are set into 5 various concentrations gradients first（In pilot study
On the basis of, bacteriostasis rate is set in the range of 5%~90% by geometric progression）.If blank, it is repeated 4 times.Given birth to using mycelia
Performance rate method long, by cultured pathogen, aseptically with the card punch of a diameter of 5mm, bacteria cake is cut from colony edge,
Bacteria cake is connected on the culture medium flat plate of various concentrations with transfer needle, is placed in 26 DEG C of insulating boxs and is cultivated 72h.Surveyed with slide measure
The growth diameter of bacterium colony is measured, the percentage that each treatment suppresses mycelial growth is calculated, by inhibiting rate niqueMin and series concentration
Linear regression analysis between logarithm value, obtains the EC of each medicament50Value.
The co-toxicity coefficient of mixture is calculated with the abundant methods of Sun Yun（CTC）, activity of the reagent agent to germ is evaluated with this.Compounding
The co-toxicity coefficient of preparation（CTC）>=120 show as synergistic effect；CTC≤80 show as antagonism；80 ＜ CTC ＜ 120 are showed
It is summation action.
The Toxicity Determination of the fluopyram of table 2 and Pyrimethanil compositional to leaf muld of tomato
The Toxicity Determination of the fluopyram of table 3 and Pyrimethanil compositional to alternaria leaf spot of apple
Toxicity Determination result shows：Fluopyram and pyrimethanil with weight ratio be 1：80~60：1 is mixed to tomato leaf mold
Disease, alternaria leaf spot of apple have synergistic function, and especially weight ratio is 1：60~40：1 synergistic effect is especially pronounced.
