In 1980, a field experiment was conducted to evaluate the effects of soil-incorporated Carbofuran (Furadan 3G) on some rice insect pests and on the growth of rice plants of the variety Milyang-23, which is one of the Korean leading varieties.
The effects were compared with those of the conventional broadcast of Carbofuran and Diazinon as local standard method.
The results obtained were as follows:
(1) The soil incorporation of Carbofuran dramatically suppressed the plant damages of the rice stem maggots (Chlorops oryzae and Hyderellia sasakii) and thrips (Baliothips biformis) at tillering stage of the rice; plant damages observed were 0.5%(1.2 a.i. kg/ha) and 0.6%(1.8 a.i. kg/ha) for the rice stem maggots, and 1.3%(1.2 a.i. kg/ha) and no damage(1.8 a.i. kg/ha) for thrips while with broadcast of Carbofuran there were 65.9%(1.2 a.i. kg/ha) and 42.4%(1.8% a.i. kg/ha) for ricestem maggots, and for the thrips, 60.6%, 36.0% with Carvofuran baoadcast, and 83.5%, 90.7% with Diazinon treatment, and 97.8% for the untreated check.(2) Soil incorporation and broadcast of Carbofuran were significantly effective for the control of brown planthoppers (Nilaparvata lugens) and the white-backed planthoppers (Sogatella furcifera), and the conventional broadcast of Diazinon was still unsatisfactory for controlling the brown planthoppers.
(3) on 38th day after transplanting, the number of tillers per hill and plant height in the soil incoporation of Carboruran revealed the significant increases over those of the Carbofuran and Diazinon brodcasts and the check; with number of tillers per hill 23.0 for 1.2 a.i. kg/ha and 25.7 for 1.8 a.i. kg/ha with number of tillers per hill 23.0 for 1.2 a.i. kg/ha and 25.7 for 1.8 a.i. kg/ha with Carbofuran soil incorporation, while they were for 20.1, 22.1, with respective doses of the broadcasted Carbofuran they were 19.1 for the broadcased Diazinon, and 18.5 for the check, on the 82nd day after transplanting, root development of rice plants grown on the Carbofuran soil incorporated sites also revealed a significant increase over the broadcasting treatments and the check in the number and length of roots.(4) Even under the unusual low-temperature conditions during 1980 in Korea, Carvofuran soil incorporation greatly promoted the heading of rice plants and consequently resulted in significant shortening of the heading time as compared to those of Carbofuran and Diazinon broadasts and the check. In addition, soil incorporation of Cabofuran resulted in much better heading status(65 to 70% in completed heading) than broadcast(35 to 37% in Carbofuran broadcast and 20% in Diazinon broadcast) and the untereated check(30%).
(5) The mexmium growth promotion of rice plants was observed from the rate of 1.8 a.i. kg/ha of the Carbofuran soil incorporation in plant height (90.0cm), stem height(78.6cm), length of uppermost internodes(24.7cm), and root weight(5.0g/hill in dry base) over the untreated check(81.9cm in plant height, 62.9cm in stem height, 19.3cm in uppermost intermodes and 3.6g in root weight) and other insecticide treated plots. However, there was no singnificant difference in panicle length among the treatments.
(6) The number of panicles per hill, number of grains per panicle and 1000-grain weight showed that Carbofural soil incorporation significantly increased those yield components as compared to the broadcast and the untreated check. Of the treatments, Carbofuran soin incorporation registered significantly higher grain yields (2,460kg/ha from 1.2 a.i. kg/ha and 2,244kg/ha from 1.8 a.i. kg/ha treatments) than Carbofuran broadcest (1,005kg/ha from 1.2 a.i. kg/ha and 1,185kg/ha from 1.8 a.i. kg/ha treatments), Diazinon broadcast(63kg/ha), and the check(849kg/ha). Showing the low yield potential of the test variety seemed to be cold-damage from unusual weather conditions in 1980.
(7) Analysis of essential macro-and micro-element contents in rice plants on the 122nd day after transplanting showed more k, Cu, Mn and Zn contents in the plants treated by soil incorporation of Carbofuran than those in the untreated check, while N and Fe were lower in the plants treated by Carbofuran than those in the untreated check, while N and Fe were lower in the plants treated by Carbofuran soil incorporation.
Amounts of K and Zn were much greater in Carbofuran soil incorporation than in Carbofuran broadcast, and N and P were greatly lower in the plants by Carbofuran soil incorporation.
(8) in conclusion, the result obtained in this study would provide some real evidences that Carbofuran incoporated with the paddy soils could be a new insecticidal application method of the maximization of rice yield through the dramatical suppressin of the plant damages of insect pests; the rice leaf stem maggots, thrips, and planthoppers, and great growth stimulation(increasing the root development, the effective tillers, panicles, etc.) of rice plants.
