First applicant uses these two kinds of compositions to carry out indoor biometrics experiment, experimental technique and result as follows:
First, after analyzing the action character of two kinds of active ingredients, the raw object surveyed is decided to be phytophthora infestans (Phytophthorainfestans (Mont.) de Bary) by us, and this bacterium can cause potato late blight.
The test method of indoor biometrics: reference standard NY/T1156.6-2006, adopts growth rate method to measure medicament to the inhibitory action of potato late blight pathogen mycelial growth.On the basis of preliminary experiment, from each medicament, design 5 concentration within the scope of 10%-90% are reached to germ mycelial growth inhibition rate, it is for subsequent use by the former medicine of 96% fluopicolide and the former medicine of 98% chlorobenzene ether acid amides with acetone to be first that solvent is made into the liquid of series concentration, then liquid is joined in 1% ratio in the PDA medium melting also cool to room temperature, after fully shaking up, pour in the culture dish (Φ 90mm) of sterilizing and make band medicine flat board, often process and repeat, to add the process of sterile water for blank for four times; With card punch (Φ 5mm) the picking phytophthora infestans bacterium cake of sterilizing, mycelia faces down aseptic inoculation in the central authorities of band medicine flat board, be inverted in the interior cultivation of constant incubator of 25 DEG C, adopt right-angled intersection method to measure colony diameter after cultivating 6d, calculate the EC of each medicament to pathogen
50, and calculate toxicity index according to the following equation, compare virulence and the bacteriostasis of different agents.Above-mentioned raw survey experiment former medicine used and reagent are all bought from other producers.
The co-toxicity coefficient method representation that the co-toxicity of mixture preparation adopts Sun Yun abundant:
The theoretical toxicity index TTI=∑ of mixture preparation (percentage of this pharmaceutically active ingredient of the toxicity index ATI of certain medicine × in mixture).
Be synergistic effect when co-toxicity coefficient CTC is greater than 120, being antagonism when being less than 80, is addition time between 80-120.
Indoor biometrics experimental data sees the following form:
Table 1 fluopicolide and chlorobenzene ether acid amides and different ratio thereof are to the measurement result of potato late blight co-toxicity coefficient
By above-mentioned data, obviously can find out that the co-toxicity coefficient (CTC) of formula is all greater than 120, the prevention and control capability of potato late blight is had to the synergistic effect of different proportion when fluopicolide and chlorobenzene ether acid amides are composite in varing proportions.
Determine fluopicolide by indoor biometrics experiment and chlorobenzene ether acid amides two kinds of active ingredients are composite can good synergistic effect, below by way of instantiation in order to further describe the present invention, but the present invention is absolutely not only only limitted to these embodiments following.In formula, percentage is all weight percentage, and the former medicine used and auxiliary agent are other producers and buy.
