1.2.2 test plant
By the cultivation of susceptible cucumber variety Chang Chun Mi Ci in pot for growing seedlings, it is placed in greenhouse and cultivates, plant grows to three to after four leaf stage,
The blade of identical leaf age is gathered, culture and measure for cucumber powdery mildew's pathogen.
1.2.3 the culture of cucumber powdery mildew's pathogen and the preparation of spore suspension
Cucumber powdery mildew's pathogen is cultivated using plants method under conditions of 20 DEG C, 12h alternation of light and darkness, turns to be commissioned to train foster 1 per 30d
It is secondary.With the conidium on sterile water elution incidence of leaf during inoculation, it is l × 10 to be configured to spore concentration6Individual/mL suspension.
1.2.4 strains tested sensitivity testing
Toxicity test is carried out using leaf dish moisturizing method.The blade of collection is first prepared into a diameter of 1.5cm leaf dish, it is random mixed
It is even, it is respectively placed in the series concentration decoction configured and soaks lh, each 50 leaf dishes of concentration, tests with the place of not adding medicine
Manage as blank control, after immersion terminates, leaf is face-up placed on the blotting paper of identical liquor strength wetting, in leaf dish
Decoction blot, by the spore suspension l0L prepared be inoculated in leaf dish center, room temperature place 5min after, be placed in 20 DEG C,
Cultivated under conditions of 12h alternation of light and darkness, the onset area in leaf dish is measured after 10d, calculates EC50。
On the basis of pilot study, toxicity test is carried out to single dose fluorobenzene ether amide and propiconazole respectively with above method, the two
EC50Value is respectively 0.9 ㎎/l and 2.8 ㎎/l.
The percentage that leaf dish area is accounted for according to lesion area divides sick level：
0 grade：Scab

1.2.3 mixture toxicity test
The toxicity test of mixture is carried out according to mixed ratio with single dose toxicity test method.
According to the abundant methods of Sun Yun by the EC of each processing of measure50Value is converted into actual mixed toxicity index (ATI)；According to the proportioning of mixture,
Theoretical mixed toxicity index (TTI) is obtained, the co-toxicity coefficient (CTC) of mixture is calculated by following equation.
Single dose toxicity index=(standard agent EC50/ reagent agent EC50)*100
ATI=(standard agent EC50/ reagent agent (mixed) EC50)*100
Toxicity index X B contents (%) in mixed of the TI I=A toxicity index X A in content (%)+B in mixed
CTC=(ATI/TTI) * 100
If co-toxicity coefficient is big by 120, show there is synergistic effect；If being significantly lower than 100 (less than 80), antagonism is shown to be；100~120
Between, it is shown to be summation action
Data are shown in Table 1,2
The virulence of the different ratio fluorobenzene ether amide of table 1 and propiconazole mixture to cucumber powdery mildew's pathogen
The co-toxicity of the fluorobenzene ether amide of table 2 and propiconazole compound to cucumber powdery mildew's pathogen
