Relationship between herbicidal efficacy of pyrazolate formulations and concentration of detosylpyrazolate in paddy water


, : Relationship between herbicidal efficacy of pyrazolate formulations and concentration of detosylpyrazolate in paddy water. Journal of Pesticide Science 12(4): 651-658

Studies were carried out to investigate the relationship between change in DTP (destosylpyrazolate) concentration in paddy water and herbicidal activity after pyrazolate [4-(2,4-dichlorobenzoyl)-1,3-dimethyl-5-pyrazolyl p-toluenesulfonate] treatment. Pyrazolate of technical grade was pulverized to provide water suspensions A, B and C which contained pyrazolate particles with a surface area of 1.13, 2.68 and 4.25 m2/g, respectively. Granules and microgranules were prepared by the extrusion method using suspension B. Test plots with or without drainage of paddy water were treated with the above five formulations. In paddy water DTP was found immediately after application, and only a small amount of pyrazolate remained throughout the test period. Correlation was found between the change in DTP concentrations in paddy water and the herbicidal performance. DTP concentration in a plot treated with suspension A was too low to show sufficient herbicidal efficacy. Suspensions B and C released DTP so fast that the herbicidal efficacy was not persistent under the draining condition, because the active ingredient had run out. The microgranular formulation released DTP in a manner similar to suspension B. A release of DTP was delayed and sustained in the granular formulation and the loss was small enough for DTP to show persistent herbicidal efficacy even under the draining condition.
