摘要：

为明确吡虫啉不同配比和不同剂量对大小粒径绿豆种子进行拌种处理的安全性,通过室内测定不同温度下不同粒径‘白绿11号’和‘科绿1号’绿豆种子发芽率,比较不同温度下二者胚芽和胚根长度,且结合田间播种试验,得出结果：20℃以上（包含20℃）两个品种发芽率无明显差异,但吡虫啉剂量大的处理的胚芽和胚根长度都明显低于对照,差异显著;20℃以下各品种吡虫啉剂量小的处理的发芽率较对照无差异,剂量大的处理均明显低于对照,胚芽和胚根长度都与对照差异显著;田间播种试验进一步验证了室内试验结果,更明确吡虫啉不同配比大田拌种的安全性。试验表明按药种比1:100拌种,吡虫啉配比≤40%,播种土壤含水量≥20%时,对大粒径绿豆安全性较高,为种子拌种防治绿豆蚜虫提供理论依据。

Abstract:

The safety of seed treatment imidacloprid on mung bean was evaluated under laboratory and field conditions. ‘Bailv 11’ and ‘Kelv 1’, two mung bean varieties with different seed sizes, were treated with imidacloprid at different proportions and dosages, the germination rate, gemmule and radicle length were examined after germination. The results showed that the germination rate of the two varieties had no difference when the cultural temperature was ≥20℃, while seeds treated with higher dosage of imidacloprid had significant lower gemmule length and radicle length compare with the contrast. Under the cultural temperature <20℃, the germination rate of the two varieties had no difference in the lower-dosage imidacloprid treatment, however, the germination rate, gemmule length and radicle length were significant lower than that of the contrast at the higher-dosage imidacloprid treatment. Result in field test further confirmed the effects of imidacloprid treatment. As a conclusion, it is safe to mung bean under a ratio of seed coating agents to mung bean seeds of 1:100, concentration of imidacloprid≤40%, soil moisture≥20%, and large seed varieties have higher safety.
