For examination pathogenic fungi: Pyricularia oryzae (ash pears spore (Pyriculariagrisea))
Reagent agent: pyraclostrobin, gibberellins
Test method: adopt growth rate method to measure the medicament virulence to pathogenic fungi. Specifically, by pyraclostrobin with gibberellins respectively with acetone solution, be made into the mother solution of 1000mg/L, mix according to the ratio of table 1, obtain mixed liquor. Then by each mixed liquor with 2% 5 Concentraton gradient of Tween 80 solution, it is subsequently adding to the PDA culture medium of 45-50 DEG C, mix homogeneously in pouring the culture dish of sterilizing into, form the culture medium plane with poison after cooling, clear water is blank, and each concentration repeats 3 times. Afterwards, by pathogen spore suspension (concentration about 1 �� 106Individual) 5 �� l instill in above-mentioned each culture medium planes, culture dish are placed in 25 DEG C, cultivate 72 hours in the incubator of humidity 90%. Then, take out culture dish, measure colony diameter, and calculate each chemicals treatment Developing restraint rate to pathogenic bacteria by following formula, and then obtain each process EC to Pyricularia oryzae50, according to each EC processed that Sun Yunpei (Y-PSun) method will measure50It is converted into actual poison exponent (ATI); Proportioning according to mixture, calculates theoretical toxicity index (TTI), calculates the co-toxicity coefficient (CTC) of mixture by following equation.
Here AM refers to the percentage by weight that composition A is shared in bactericidal composition, and BM refers to the percentage by weight that composition B is shared in bactericidal composition.
If co-toxicity coefficient is more than 120, it was shown that have potentiation; If lower than 100, it was shown that for antagonism; Between 100 ~ 120, it was shown that for summation action.
Table 1 rice blast fungus toxicity test
By table 1 result it can be seen that pyraclostrobin and gibberellins composite after, in the scope of 100:1 to 1:100, rice blast is had potentiation.
2. fusarium graminearum toxicity test
For examination pathogenic fungi: fusarium graminearum (F.graminearum schw (Fusariumgraminearum))
Reagent agent: pyraclostrobin, gibberellins
Test method: adopt growth rate method to measure the medicament virulence to pathogenic fungi. Specifically, by pyraclostrobin with gibberellins respectively with acetone solution, be made into the mother solution of 1000mg/L, mix according to the ratio of table 1, obtain mixed liquor. Then by each mixed liquor with 2% 5 Concentraton gradient of Tween 80 solution, it is subsequently adding to the PDA culture medium of 45-50 DEG C, mix homogeneously in pouring the culture dish of sterilizing into, form the culture medium plane with poison after cooling, clear water is blank, and each concentration repeats 3 times. Afterwards, by pathogen spore suspension (concentration about 1 �� 106Individual) 5 �� l instill in above-mentioned each culture medium planes, culture dish are placed in 25 DEG C, cultivate 72 hours in the incubator of humidity 90%. Then, take out culture dish, measure colony diameter, and calculate each chemicals treatment Developing restraint rate to pathogenic bacteria by following formula, and then obtain each process EC to fusarium graminearum50, according to each EC processed that Sun Yunpei (Y-PSun) method will measure50It is converted into actual poison exponent (ATI); Proportioning according to mixture, calculates theoretical toxicity index (TTI), calculates the co-toxicity coefficient (CTC) of mixture by following equation.

(3) percentage of seedgermination test
For planting experimentally son: corn seed (Zheng Dan 958)
Reagent agent: gibberellins, pyraclostrobin
Test method: adopt method for soaking seed to measure the germination percentage of seed. Specifically, put into the filter paper two of diameter 9cm in the culture dish of diameter 10cm, add about 5ml distilled water, make filter paper uniform wet, standby. Take a certain amount of corn seed, sterilize 3 minutes with 0.5% aqueous sodium hypochlorite solution, then use distilled water rinsed clean. Being soaked seed 12 hours in medicinal liquid shown in table 3 respectively by seed afterwards, often process 50 seeds, clear water is blank. The seed soaked seed uniformly is put on the filter paper in off-the-shelf culture dish, covers ware lid. Afterwards, culture dish being put into seed germination box, temperature controls at 10 DEG C, and at the mid-water container of germinating box, makes case humidity close to saturated. During germination, culture dish ventilation every day is once. Germination is checked after 96 hours. Test repeats 4 times, averages, and result is shown in table 3 below.
Table 3 corn seed germination is tested
