An addition of colloidal sulfur (Ⅰ) containing 45% of sulphite by-product of pulp to the solution of systemic fungicide Di-xiu-na(Ⅱ)with sodium sulfanilate (Ⅲ) as its active ingredient was found to facilitate the deposition of Ⅲ on and thus to significantly increase the penetration of Ⅲ into groundunt plants by 49.2%. It was found to be more effective than saponin or "Tween. 80". The amount of Ⅲ within the leaves was measured to be 432 μg/g of fresh leaf in 24 h after spraying with 0.2% Ⅱ and gradually...

An addition of colloidal sulfur (Ⅰ) containing 45% of sulphite by-product of pulp to the solution of systemic fungicide Di-xiu-na(Ⅱ)with sodium sulfanilate (Ⅲ) as its active ingredient was found to facilitate the deposition of Ⅲ on and thus to significantly increase the penetration of Ⅲ into groundunt plants by 49.2%. It was found to be more effective than saponin or "Tween. 80". The amount of Ⅲ within the leaves was measured to be 432 μg/g of fresh leaf in 24 h after spraying with 0.2% Ⅱ and gradually decreased on the following days. However, on the 10th and 15th day there were still 270 and 239 μg/g of fresh leaf respectively which were high enough to give control efficacies of 85.0% and 75.4% respectively against rust. The results showed that spray schedule with an interval of 10-15 days for practicsl use in the past was reasonable; an interval of 14-15 days might be more desirable.,While taking phytotoxicity into consideration.Under the experimental conditions of the present study a theoretical minimum concentration for inhibiting the growth of the pathogen within the leaf was 327 μg/g of fresh leaf which was found to be close to that of practical observations-357-376 μg/g of fresh leaf.The main phytotoxicity symptom of Ⅲ in groundnut plants is chlorosis of leaves , which can be reduced remarkably either by applying MgSO4.7H20 to the soil at a concentration of 0.1g/kg of soil or by adding it at a concentration of 2.5% to the solution of Ⅱ for foliar spray.

在敌锈钠(Ⅰ)药液中加入0.5%胶体硫(含45%造纸废液),能增加对氨基苯磺酸钠(Ⅱ)在花生叶面的附着量并使内吸量较单纯使用Ⅰ提高49.2%,其效果高于皂素和“吐温”80两种表面活性剂。 在本研究的试验条件下,接种时叶片内Ⅰ的最低抑菌浓度的理论推算值为327微克/克鲜叶,接近于357~376微克/克鲜叶的实际观察值;另一方面,对花生植株喷施0.2%Ⅰ后,叶片内Ⅱ的含量在24小时内可达到432微克/克鲜叶,随后即开始下降,第二天至第五天内可相对稳定在322~326微克/克鲜叶之间。不过,到第十天和第十五天时仍能分别维持207和239微克/克鲜叶,理论计算的抑菌效果分别可达85.0%和75.4%。这就进一步说明喷药的间隔期定为10~15天是可以的,可能10~12天更为合适。 Ⅱ对花生植株的毒害,可用0.1克/公斤土以上的MgSO_4·7H_(2)O浇土或在喷施的敌锈钠药液中加入0.25%以上的MgSO_4·7H_2(O),使其显著降低。

The total sales for pesticides throughout the world in 1983 was 12.8 billion US dollars. In the last 10 years, the sales for herbicides occupied the first place among the total sales of pesticides. Pyrethrinisto rank first in the insecticides; however organophosphorus and carbamate insecticides will remain to be consumed in a big amount.

The total sales for pesticides throughout the world in 1983 was 12.8 billion US dollars. In the last 10 years, the sales for herbicides occupied the first place among the total sales of pesticides. Pyrethrinisto rank first in the insecticides; however organophosphorus and carbamate insecticides will remain to be consumed in a big amount. In the fungicides, there are over 80 different kinds of non-systemic fungicides and more than 40 kinds of systemic fungicides. Among the new varieties of fungicides, the most attractive one is triazole compound. The changeover of herbicides is considerably slow. Special attention has been paid to the mixed formulations of herbicides outside of China. The annual growth rate of plant growth regulators between 1970 to 1982 was 14.2 %. As to the formulations of pesticides, colloids and slow-releasing formulations develop very rapidly. In the applications of pesticides, static spray technology merits attention.

1983年,世界农药总销售额为128亿美元。近十年,除草剂消费额在农药中占第一位。在杀虫剂中,拟除虫菊酯类杀虫剂将占首位,但有机磷与氨基甲酸酯类杀虫剂仍将大量使用。在杀菌剂中,非内吸性杀菌剂有80多种,内吸性杀菌剂有40多种。杀菌剂新品种中引人注目的是三唑类化合物。除草剂品种更换较慢,国外对除草混剂特别重视。植物生长调节剂1970~1982年间的年增长率为14.2%。农药剂型中胶悬剂与缓释剂发展很快。施药方面值得重视的是静电喷雾技术。
