Through the diversity investigation of weed in large area of white clover seed production atMaming （1）In the seed production of white clover in large area, by the growing of white clover, the species and quantity of weed are increasing rapidly;（2） Because the growth speed of white clover is slower than other grass in the seeding year,the early field management is effect to prevent the fast growth of the weeds.

通过对农业部白三叶种子生产项目在云南省马龙县马鸣乡大面积生产中杂草的多样性调查，结果表明：（1）在白三叶种子大面积生产中，随着白三叶的生长，田间杂草的种类和数量逐步增加；（2）由于在白三叶播种当年其生长速度不快，因而在其生长前期应适时除杂，以防止杂草的迅速生长。

Through the field test and indoor research for about 3 years, it was found that the occurrence of cotton Fusarium wilt had close relationship with the climate condition in Xinjiang. when temperature was about 20℃, disease index developed very quickly. when temperature was above 24℃, disease index would reduce. With temperature dropping by the end of July and at the beginning of August, disease index would raise again.

通过田间试验和室内研究发现，新疆棉花枯萎病的发生与气候有十分密切的关系，在地膜植棉的情况下，当气温达20℃左右病指上升最快，气温达24℃以上则很快进入高温隐症期；7月下旬或8月上旬随温度下降，病情又有回升，故枯萎病在新疆也有两个明显的高峰期，只不过因地膜植棉发病期明显提前而已。

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.

食下毒力试验结果经Pearson拟合度检验表明，氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.0905×10^(-3)mg/L，致死中量(LD50)为1.1435×10^(-8)mg/头；药剂在常规浓度下对家蚕无熏蒸毒性；1.25×10^(-4)mg/L稀释药液对桑树根灌和喷叶处理，表现极强的根部、叶部和全株性内吸传导特性；药液对家蚕的残毒期很长，1.25×10^(-4)mg/L稀释药液田间喷雾桑叶，间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%，且中毒反应极快，添食毒叶后1~5 h出现中毒症状，经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。
