Performance test the fungicidal compositions of the present application were used for controlling botrytis cinerea, and each of examples and comparative examples was provided with a test area of 10m 2 The application rate is 50 g/mu, and the spray application is carried out. Samples were taken 1h,1d,3d,5d,7d,14d,21d,30d and 50d after dosing, using a five point sampling method, 10cm of soil was drilled each time for detection. Residual amount in soil is detected by using a gas chromatograph so as to be plotted backHalf-life was calculated by equation.
TABLE 2 data sheet of residual iprodione in soil
TABLE 3 data table of digestion rate and half-life of residual iprodione in soil
It can be seen from the combination of example 6, comparative example 1 and comparative example 3 and the combination of table 2 that only by adding the white rake powder, although a certain amount of nutrients can be provided for the bacterial reproduction, the raw materials are dispersed and the subsequent supply of nutrients cannot be continued, so that the bacterial reproduction cannot be continued in large quantities, thereby making the decomposition efficiency not high.
As can be seen from the combination of example 6, comparative example 2 and comparative example 3 and the combination of table 2, the lack of the white rake teeth powder provides the bacteria with nutrients required for the initial growth, the initial growth of the bacteria is slow, and the milk vetch pollen in the modified coconut husk is difficult to reach, so that the decomposition efficiency of the raw medicine is low.
As can be seen from the combination of example 6, comparative example 4 and comparative example 5 and the combination of table 2, the white rake teeth powder provides nutrients for the initial growth of bacteria in the soil, the bacteria in the soil are propagated in large quantity and contacted with the modified coconut husk, and then the milk vetch pollen further provides nutrients for the growth of bacteria, thereby promoting the further propagation of bacteria to decompose the original medicine.
As can be seen by combining examples 2-10 and table 2, the half-life time can also be effectively reduced by adjusting the addition of the white harrow teeth powder and the loading agent, the white harrow teeth powder provides nutrition for bacterial growth in soil, and after bacterial propagation in soil contacts with the modified coconut husk, the milk vetch pollen further provides nutrition for bacterial growth, thereby promoting bacterial propagation on the modified coconut husk and further decomposing the raw medicine.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
