The environmental character of a pesticide is among the important aspects in making a comprehensive assessment of it. This paper presents a study of the behaviour of ~(35)S-labelled Shachongshuangin its absorption,mobility and degradation in soil, its stability in water, and its absorption and excretion by the grass carp (Ctenopharyngodon idellus).The results of the study reveal its low absorption and high mobility, especially water-carrying mobility in soil, fair stability in soil and water,slowness in degradation, and the main produet of degradation, Nereistoxin,being of lower mobility in soil than its maternal compound. From these,a conclusion may well be draw that this pesticide is likely to enter theriver system and affect the environment of the aquatic ecosystem.In water contaminated by the pesticide, it entered the bodies of grass carps (Ctenopharyngodon idellus) along with the foodstuff——the duckweedor via the respiratory tracts, and mostly accumulated in the viscera,However, after these fishes were removed from the contaminated source, the radioactive specific activity in the body diminished rapidly as time went by, especially in the flesh. This showed that the pesticide could be excreted from the body and no biological concentration resulted.In view of the environmental character of the pesticide and its absorption by fishes, care should be taken in the management of the water in paddy fields not to drain water away shortly after the pesticide is applied.It is also important to prevent leakage so as to maintain its efficiency and reduce its effect on the environment of the aquatic ecosystem.

农药的环境学性质是全面评价农药的要素之一。本文系应用放射性同位素示踪技术,研究了硫—35标记的杀虫双在土壤中的吸附、移动、降解、水中的稳定性和草鱼(Ctenopharyngodon idellus)的吸收、排泄。结果表明:~(35)S-杀虫双在土壤中的吸附性甚小,移动性较大,能随水迁移,在土壤和水中比较稳定,降解缓慢,降解物主要为沙蚕毒素,而它在土壤中的移动性较其母体为小,因此,杀虫双有可能随水进入水系影响水生生态环境;而从草鱼在“污染”的环境中对~(35)S-杀虫双的吸收、蓄积及其离开“污染”源后的排泄情况来看,它可以通过饵料“芜萍”经口和呼吸吸收进入鱼体,且在鱼体内的分布是不均匀的,内脏的含量最高;而当吸收、蓄积了~(35)S-杀虫双的鱼体离开“污染”源后,鱼体内的放射性比强度则随时间的增加而迅速减少、尤以鱼肉的消失最快,充分说明,草鱼在“污染”环境中吸收、蓄积的杀虫双,一旦切断“污染”源,是可以迅速排至体外,无生物浓缩现象。鉴于杀虫双的环境学特性及鱼体的吸收,应加强稻田水的管理,避免施药后短期内即将田水排出,并减少渗漏,以保持药效,减少对水生生态环境的影响。

The present paper deals with the residue of Ordram in water, soil and riceplants. It was found that Ordram degraded rapidly in water and soil of paddyfields. The half degraded period was 4-5 days in water and 10-12.5 days in soil.The residue in harvested rice grains was less than 0.005mg/kg, and in straw andrice bran less than 0.02 mg/kg. The authors suggest that MRL of Ordram in rice should be 0.1ppm and150-250 ml/acre of 96% Orrdram mixed with sand and applied 5-14 days afterplanting would be safe.

本文研究了禾大壮在稻田木,土壤中的消失动态和水稻上的残留状况,结果表明:禾大壮在稻田水和土壤中消失很快。水中半衷明为4~5天。土壤中半衰期为10~12.5天。收获的稻米中禾大壮残留量低于0.005mg/kg。稻草和糠中均低于0.02mg/kg。禾大壮在稻米中的RML可定为0.1mg/kg。96%禾大壮乳油每亩150-250毫升在水稻移栽后5-14天拌砂撒施是安全的。

Rice leaf miner, Hydrellia griseola fallen, is a major pest of rice production region in Jilin province. Damage occurs almost every year in some locations. It passed in the adult stage in the winter. The larvae of Ist-brood caused most injury to transplanted rice seedlings, Peak egg deposited by overwintered female flies generally occurred from the late May to early June, and the larvae were most numerous in early June and attacked the rice seedling leaves.

水稻潜叶蝇是吉林省水稻产区的主要害虫,在一些地区几乎每年危害。以成虫越冬,以第一代幼虫对刚插完秧的水稻苗期危害最重。越冬雌虫的产卵高峰期从5月末到6月初,幼虫大量发生是6月上旬危害稻苗叶子。 1985年在田间小区比较了10种农药防治效果,只有用拌磷颗粒剂防治效果最好。1986年在九台、东丰、海龙、磐石、敦化等地水稻产区进行了大面积颗粒剂田间防治试验,所有试验都证明5%甲拌磷颗粒剂防治效果好,每公顷用量是3.75至7.5公斤,直接施在水里,时间是6月1日至5日,这时水稻田水必须保持一星期,降低虫口密度95%以上。我们推荐这种方法做为防治水稻潜叶蝇的推广措施。
