Abstract
The experiment was conducted to obtain basic information on occurrence ecology system of Aneilema japonica and to establish its effective control systems in dry seeded rice at National Yeongnam Agricultural Experiment Station in 1995. Total amount of weed in dry seeded rice in the following year('95) as affected by control of barnyardgrass at 70 days after seeding(DAS) in previous year('94) was reduced 47.7% at 30 DAS and 7.8% at 60DAS and also exhibited different weed occurrence as compared with no control plot. Especially in control plot at 60 DAS, occurrence of Echinochloa crus-galli was reduced by 46.9%, But the growth of Aneilema japonica which is one of the problems in weed species was drastically increased by 231 % and Persicaria hydropiper by 11.8%, respectively. Suppressed tillering of rice plant as affected by occurring of A. japonica(300-750 plants/) occurred from about 40 DAS and rice grain reduced 74-93% compared with hand weeding due to reduced panicle number. Soil applied Butachlor(EC) at 5 DAS, foliar applied Propanil -Butachlor(EC) at 13 DAS and Lgc 40863+Pendimethalin at 20 DAS were very effective for Aneilema japonica. As considering both weed suppression of Aneilema japonica and yield capacity, middle late foliar application of Lgc 40863+Pendimethalin and systematic application of Butachlor at 5 DAS followed by Propanil/Molinate at 25 DAS were the most effective control systems.
