Laboratory test by filter-paper disc method shows that organic mercurials arehighly toxic to the spores of the rice blast fungus.Ethyl mercury phosphate giveslargest inhibition zone,ethyl mercury chloride the next,and phenyl mercuryacetate the smallest of the three compounds tested.With bordeaux mixture,littleor no appreciable distant action has been observed. Cement plot experiment indicates that a mixture of 1 part phenyl mercuryacetate to 5 parts hydrated lime or 1: 15 and 1: 20 ethyl mercury chloride andhydrated lime applied as dust give much better control of rice blast than bor-deaux mixture.These fungicides are not injurious to rice plant except causing afew necrotic spots on the leaves. Similar results were obtained in field experiments.Plants dusted 2-3 timesduring the growing season yielded 25-158% higher than the untreated.

茶短须螨(Brevipalpus obovatus Donnadieu)是茶树上一种重要害螨。寄主范围广,能为害45科120多种植物。全年发生7代。以雌成螨在表土下根颈部越冬,但在我国南方茶区则无明显的滞育现象。螨体和卵多分布于茶树中、下部,以成叶或老叶的背面居多。雌、雄性比约2000∶1,以行孤雌生殖为主,也可行两性生殖,后代绝大多数为雌螨。雌成螨平均寿命为35—46天,长的可达6个月,平均产卵量35—40粒。在杭州地区,每年4月份平均气温上升至10—15℃时开始出蛰;24—30℃为适温范围,8月中旬—9月中旬,当旬平均气温高于24℃、降雨量小于40毫米、日照时数在60—100小时,20—30天后常会出现发生高峰,全年一般有两个高峰;平均气温低于17℃时,雌螨陆续进入滞育阶段。秋茶结束后(10月中旬)进行清园,并喷施0.5°Be 石硫合剂,可以有效地消灭越冬雌螨。发生高峰期之前(7—8月份)喷施棉油皂50倍液(暂订安全间隔期7—10天)、50%普特丹(三环锡)4000—6000倍或20%双甲眯1000倍液(暂订安全间隔期15天)对螨和卵均有较好的防治效果
