以稻谷、小麦或玉米重量百万分之3或5的林丹粉剂(含有99%以上γ-异构体的工业品六六六)拌合,在多种不同的储藏条件下,已足以有效地防治米象、谷蠹、长角扁谷盗和拟谷盗等储粮害虫,药效可达一年之久。以百万分之5的林丹处理过的储粮,经过一年的储藏,按照我国地方习惯加工成熟食品米饭、馒头、窝头等,相当的林丹残留量为百万分之0、0.05—0.57、1.03—1.10。试验证明用百万分之5的林丹拌合稻谷防治储粳害虫具有以下的特点:储粮经脱壳、精碾、淘洗、蒸煮成米饭之后,原拌入的林丹己无残留或接近于无残留。一年的大白鼠和豚鼠饲养,证明饲料中若含有百万分之5以下的林丹,对于以上两种动物的发育和内脏组织完全无害。
Mixing lindane powder (an industrial product containing more than 99% of the γ-isomer) of 3 or 5 parts by weight of rice, wheat or maize under various storage conditions is sufficient Prevention and control of rice elephant, Valley beetles, long-angle Bianni Pi and grain storage pests and other grain Pirates, efficacy up to one year. 5 million lindane processed grain storage, after a year of storage, in accordance with our local habits of cooked food cooked rice, bread, wotou, etc. considerable lindane residues of 0,0.05-0.57 million, 1.03-1.10. The experiment proved that using 5 parts per million lindane to mix and control rice has the following characteristics: After the stored grain is shelling, fine grinding, washing and cooking into rice, the originally mixed lindane has no residue or is close to No residue. One year of rat and guinea pigs feeding, if the feed contains less than 5 ppm of lindane, for the development of these two animals and visceral tissue completely harmless.
