Abstract
The effects of four pesticides commonly used in rice field and their mixtures on rice grain growth were studied by using a grain growth equation.ANOVA showed that maximum growth value(K),initial growth power(R0)and accumulative weight of dry matter during active growth stage(GT)for superior grain were not significantly different among all treatments.Multiple comparisons showed that GTs of rice treated with bisultap at 675 g/hm2 and the mixture of the four pesticides at high dosage(150 g/hm2 jinggangmycin + 45 g/hm2 imidacloprid + 675 g/hm2 bisultap + 300 g/hm2 tricyclazole)were significantly greater than that of 22.5 g/hm2 imidacloprid,but not significantly different compared to control.In general,for low dosages of three pesticides,jinggangmycin,bisultap and imidacloprid,and their mixtures,there was no significant impact on superior grain growth,but significant on inferior grain growth.K for control was maxmium in all the pesticide treatments,and that for the mixture of the four pesticides at high dosage was minimum.In addition,GT for 22.5 g/hm2 imidacloprid and the mixture of the four pesticides at high dosage was significantly less than that of control.Mixture application of the four pesticides at high dosage had a significant negative effect on inferior grain filling.
