0.5% azadirachtin microencapsules (Azadirachtin MC) manufactured with the method of "common solid phase grinding" are made from β-CD and azadirachtin. In a laboratory assay, the LC_(50) of Azadirachtin MC against the 4~(th) instar larvae of Pieris rapae were determined to be 4.3202±0.3180 mg/L and its CL_(0.95) 3.7389~4.9913 mg/L. P. rapae apparently refused to eat the food treated with Azadirachtin MC at 5~260 mg/L with an anti-feeding rate of 85.60%~82.44% and an anti-feeding index of 11.82~14.94. Field...

Field spray with Azadirachtin MC solution at 10, 6.25 and 4.55 mg/L gave a corrected control efficiency of (85.89%), 82.95% and 78.97%, respectively, as determined 3 days after the treatment and 81.86% 82.48% and 80.88% as determined 7 days after the treatment. In contrast, the control efficiency of Azadirachtin EC was 77.31% and that of Pardon was (84.38%). ANOVA showed that no significant difference was present among them at P=0.05.

BaTiO3 nanopowders were synthesized by the combination of solid phase grinding and low temperature(200 to 300℃) calcination method,using barium hydroxide and tetrabutyl titanate as reactants.The products prepared were characterized by XRD,TEM,IR and ICP;and the formation process of the nanopowders was investigated by means of TG-DTA.The results show that the prepared BaTiO3 nanopowders with particle sizes of 15 to 20nm and almost spherical particle shape are cubic phase,and their molar ratio of barium to titanate is about 1.0.The phase transition from cubic to tetragonal phase of barium titanate occurrs when the temperature of heat treatment is 800 to 1000℃,and the hydroxyl ions existing in the lattice of BaTiO3 is removed when the temperature of heat treatment is 668 to 892℃.
