A new pyrethroid compound of the field soil termite control? ...
Soil pH value on the residual amount of permethrin is not great. These results suggest that the practical application of compound T in soil type may have a wide range of adaptability to facilitate its application. Table 3 The main physical and chemical properties of soil samples Table3Somebasicphy Qiu caLchemaIpropertiesofsollused Table 4 soil samples A, B permethrin content of Pu layers inspection Table4t-Testofthepermethrincontentofeverylayerinsobs Table 5 the initial field test block virulence test results Table5Primarytoxicityofthetreatedsoils 4 into the Tan-speed. Pyrethroids such as a new type of anti-termite soil dark field polyphony agent pan residue 4132.2.5 residual respect for most pesticides,[link widoczny dla zalogowanych], the soil organic matter content is the most important of solid absorption factor]. But we both indoor soil leaching experiments is less organic matter content of the yellow clay surface adsorption of permethrin more. The field test showed the two residues of permethrin in soil no significant differences in the distribution. Leaching experiment, we note that Huang has compacted soil column, revolves around the phenomenon of soil,[link widoczny dla zalogowanych], leaching through soil water velocity significantly slower than the tide,[link widoczny dla zalogowanych], we think this may be fools in the yellow soil permethrin in the soil column down one of the reasons is not easy . Field test block is more complex. Obviously, in the rain leaching yellow clay under the surface runoff is higher than the alluvial soil and may yellow clay adsorption strength permethrin lower than the alluvial soil, so rainwater leaching in the soil under the yellow,[link widoczny dla zalogowanych], revolves around the loss of pharmaceutical t Although the loss is very small) more than the alluvial soil, on the other hand, alluvial soil organic matter content is high, the adsorption force on the pharmaceutical may be stronger, but the turn which the decomposition activity of microorganisms and higher pharmaceutical, and its decomposition the amount of loss may be more yellow clay and bigger. But to understand the exact difference between different experimental results still need further experimental study. Acknowledgements: I thank the Sichuan Academy of Forestry,[link widoczny dla zalogowanych], Liu Zhi, vice president of sliding, Mr. Tang Guoqing in the field test site selection and field blocks the production process of dry pan passion to help the four states to wash the boat Agricultural Science Analysis Test Center administration and Mr. Luo Lingshi rejection of Chinese Studies Gas chromatography analysis of persons in the warm help. Fan review of the manuscript German professors would propose amendments Well, Han Wei, deputy director of both the production and Gap in the field test given during the sampling is also a great help thanks Well
