1964年5月18日至6月1日于宿县等地就对氨基苯磺酸的防锈效果进行了調查,現將调查结果簡报如下。据宿县病虫测报站在宿县符离农場和該站与符离农技站配合在黄山公社股河大队两地所进行的田间試驗,用0.5—0.6%的对氨基苯磺酸分別于4月28日和5月15日共噴药两次(小区面积零点二亩,各重复一次)。5月22日药效检查,防治区碧螞一号稈锈病株率较对照区降低39.5%,嚴重度降低5—10%。与同期喷洒波美零点五度石硫合剂处理比较(病株率降低1.5%,嚴重度降低5%),0.5—0.6%对氨基苯磺酸防治效果显著高于波美零点五度石硫合剂。
From May 18, 1964 to June 1, 1964, the anti-rust effect of sulfanilic acid was investigated in Suxian County and other places. The survey results are summarized as follows. According to Suxian Pest Report Station in Suxian Fu from the farm and the station and Fu from the agricultural station in Huangshan commune shares River Brigade conducted field trials in both places, with 0.5-0.6% of the sulfanilic acid respectively On April 28 and May 15, a total of two times spraying (plot area of two acres, each repeat). May 22 test results, control area Bi Mao No. 1 rust rust plant rate was 39.5% lower than the control area, reducing the severity of 5-10%. Compared with the spraying of Bauhinia spar Lignosulphate at the same period (strain rate reduced by 1.5% and severity decreased by 5%), the control effect of 0.5-0.6% p-aminobenzene sulfonic acid was significantly higher than that of Pomegranate zero point Sulfur Sulfate mixture.
