摘要: 为了评估5%四聚乙醛颗粒剂在稻虾共作模式下对福寿螺(Pomacea canaliculata)的防治效果及对水稻的保苗效果,在湖北省潜江市稻虾共作田进行田间试验。设置7.5 kg/hm2 6%四聚乙醛颗粒剂(T1)以及4.50、6.75、9.00 kg/hm2 5%四聚乙醛颗粒剂(T2、T3、T4)处理,并设空白对照(CK,不施药)。于施药后1、2、7、14 d调查福寿螺死亡率、卵块数量及水稻秧苗损失率,计算防治效果和保苗率。结果表明,施药后14 d,各药剂处理福寿螺死亡率均达80%以上。与T1处理相比,T2、T3、T4处理在施药后1 d的福寿螺死亡率分别显著提高71.11%、86.67%和95.56%。5%四聚乙醛颗粒剂各处理在抑制福寿螺卵块数量和减少水稻秧苗损失方面的效果均显著优于6%四聚乙醛颗粒剂处理。其中,T3处理的防治效果在施药后7 d和14 d分别达94.78%和99.12%。综合考虑防治效果与环境影响,推荐使用4.50~6.75 kg/hm2的5%四聚乙醛颗粒剂进行福寿螺防治。

Abstract: To evaluate the control efficacy of 5% metaldehyde granules against the golden apple snail (Pomacea canaliculata) and their protective effect on rice seedlings under the rice-crayfish co-culture system, a field experiment was conducted in rice-crayfish fields in Qianjiang City, Hubei Province. The treatments were set as follows:7.50 kg/hm2 of 6% metaldehyde granules (T1), 5% metaldehyde granules at doses of 4.50, 6.75, and 9.00 kg/hm2 (T2, T3, T4), and a non-treated blank control (CK). Snail mortality, the number of egg masses, and rice seedling loss rate were investigated at 1, 2, 7, and 14 days after application. The control efficacy and seedling protection rate were calculated accordingly. By 14 days after application, snail mortality in all metaldehyde-treated plots exceeded 80%. Compared with the T1 treatment, the mortality rates in T2, T3, and T4 treatments were significantly increased by 71.11%, 86.67%, and 95.56%, respectively, at 1 day after application. All treatments with 5% metaldehyde granules were significantly more effective than the 6% metaldehyde granule treatment in suppressing egg mass numbers and reducing rice seedling loss. Notably, the control efficacy of the T3 treatment reached 94.78% and 99.12% at 7 and 14 days after application, respectively. Considering both control efficacy and environmental impact, an application rate of 5% metaldehyde granules ranging from 4.50 to 6.75 kg/hm2 was recommended for the management of the golden apple snail.
