The purpose of this experiment was to evaluate the effectiveness of several ganular insecticides in controlling the pests infestating on young watermelon plants. One-third of the insecticide was applied into planting holes prior to planting and the other two-thirds was side-dressed 10 days after permanent planting. The infestation of several pests was investigated at 10, 30, 50, 70 and 90 days after the second application of the insecticides. Thimet 10% and Temik 10% G were most effective in controlling Taiwan giant cricke (Brachytrupes portentosus) followed by Terracur-P 5% G, Furadan 3% G and Contraven 10% G. Furadan while 3% G and Temik 10% G were effective in controlling cotton aphid (A.gossypii) and the effect could persist for 50 to 70 days. All the tested insecticides showed an effect of 30 to 50 days days in controlling thrips (Thrips flavus). The most significant results were observedon the application of Furadan 3% G and Temik 10% G. Furadan 3% G, Contraven 10% G were effective in reducing the population of leaf miner (Liriomyza sp.) while Temik 10% G was the most effective insecticide in controlling the red mite (Tetranychus kanzawai) for up to 70 days after planting. |
