Title: Research on Effect of Cure and Prevention of Weeds in Rice Field by Using Four Herbicides
Abstract: According to the occurrence of weeds in rice transplanting,in this paper,four herbicides(22% Bensulfuron methyl-acetochlor WP,10% Pyrazosulfuron-ethyl WP,56 % MCPA-Na PX,40% Prometryn WP)were applied to investigate the control effects of Echinochloa crusgalli,Digitaria sanguinalis,Monochoriapauciflora,Sagittariatrifolia,Cyperus rotundus L.,Marsilea quadrifolia L..The results showed that four herbicides had good control effects for weeds.The best control effect for Digitaria sanguinalis were 40% Prometryn WP(98.4%)and 22% Bensulfuron methylacetochlor WP( 98.2 %); The best control effect for Echinochloa crusgalli and Sagittariatrifolia was 22 % Bensulfuron methyl- acetochlor WP(91.5%,85.2%);four herbicides had good control effects for Cyperus rotundus L.,Marsilea quadrifolia L.and Monochoriapauciflora.After 22%Bensulfuron methyl-acetochlor WP treatment,the rice yield was the highest(10 080.00 kg/hm2).Therefore,22% Bensulfuron methyl-acetochlor WP was the best herbicide to control rice field weeds.
