| 摘 要： | 本試驗是1962年結合生产进行的。結果表明,粮堆中拌合百万分之5的林丹粉剂,以全部拌合防治效果最好;分层或表层拌合的,防治效果较差。无論那种拌合方式都可以有效地防治麦蛾;在原始害虫不多的情况下,对米象、长角谷盜和谷蠹也有良好防治效果,但对防治鋸谷盜和米虱,效果不明显。用百万分之5的林丹粉剂拌合小麦,加工后,林丹的残留量在机制粉中为百万分之1.1—2.5,石磨制粉中为百万分之1.7—3.9,麸皮中为百万分之4.8—10.4。表层拌合的小麦加工成面粉后,为百万分之0.3,麸皮中为百万分之1.2。全部拌合的稻谷加工后,大米及米糠中分別为百万分之0.57—1.0和4.6—12.0,分层拌合的稻谷加工品中則分別为百万分之0.42和2.0。全部拌合的玉米,加工成玉米粉后为百万分之1.9—3.7。上述拌合浓度,对种子发芽率没有影响。

| Abstract: | In 1962 field trails were set up to evaluate the effectiveness of the three methods used in mixing of lindane protectant dusts for the control of pests in stored grain. The most effective method was to mix the lindane dusts homogeneously with the grain at a level of 5 p.p.m, of actual lindane. Admixture of the dusts to alternative layers of 0.5-1 m. in thickness or admixture of the dusts only to the surface layer of the grain during the filling of a bin was less effective. All the above methods of mixing showed fulI protection against the Angoumois grain moth, but they were sufficient to control the rice weevil, lesser grain borer, fiat grain beetle and flour beetle only when their initial infestations were at a low level. Admixture of 5 p.p.m, of actual lindane in stored grain was insufficient to prevent the infestation from saw-toothed grain beetle and book lice. Residues in the milled products of stored wheat treated with 5 p.p.m, of actual lindane after 3-9 months of storage were ranged as follows: 1.1-2.5 p.p.m, in the flour processed in the mill, 1.7-3.9 p.p.m, in the flour processed by the millstone and 4.8-10.4 p.p.m, in the wheat bran. Residues in the products of wheat with only the surface layer treated with 5 p.p.m. of actual lindane were 0.3 p.p.m, in the flour and 1.2 p.p.m, in the bran. With the rough rice treated with 5 p.p.m, of actual lindane, the residues were 0.7-1.0 p.p.m, in the milled rice and 4.6-12.0 p.p.m, in the bran. Residues from the rough rice treated by admixture of lindane dust to alternative layers were 0.42 and 2 p.p.m, in the milled rice and bran respectively. Residues in the corn flour were 1.9-3.7 p.p.m.. By this applied dosage, lindane had no detrimental effect on the germination vigor of various grains tested. |
