Embodiment
To further instruction of the present invention, but the present invention is not limited thereto below in conjunction with embodiment.Percentage in following examples all is weight percentage.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.
Implementation of an application example one: Prochloraz or its salt and Carbatene (or zineb) are composite to the cucumber anthracnose Toxicity Determination
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 5 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament cucumber anthracnose.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR<0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR>1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively Prochloraz or its salt and Carbatene (or zineb) shared ratio in combination
A is Prochloraz or its salt
B is Carbatene (or zineb)
Result of the test is as shown in the table:
Table 1 Prochloraz or its salt, Carbatene and composite toxicity test analysis of results table thereof to cucumber anthracnose
As shown in Table 1, Prochloraz or its salt, Carbatene are to the EC of cucumber anthracnose
50Be respectively 20.42mg/L and 22.68mg/L.Prochloraz or its salt and Carbatene were mixed in the scope at 32: 1~1: 32 and all show obvious synergistic effect.Wherein, both mixed synergies in 16: 1~1: 16 scope are comparatively desirable, and mixed synergies is particularly outstanding in 8: 1~1: 8 scope.
