为了解60%环.敌WP在不同品种蔗田应用的安全性,通过田间小区试验测定了6个常栽甘蔗品种对60%环.敌WP的敏感性。结果显示,粤糖95/168的敏感性最高,新台糖16号的敏感性最低,二者差异显著;新台糖22号、桂糖11号、桂糖21号、粤糖94/128等4个品种对60%环·敌WP的敏感性介于上述二者之间,这4个品种对60%环·敌WP敏感性虽有差异但不明显,表明甘蔗对60%环.敌WP的敏感性与品种有关,从某个品种的敏感性不能推断该品系所有品种的敏感性都是低的或高的。因此,要明确甘蔗品种对60%环·敌WP的敏感性,必须进行试验测定。
In order to understand the safety of 60% Cyclobalanopsis WP in different varieties of sugarcane field, the sensitivity of six conventional sugarcane cultivars to WP of 60% were determined by field plot experiments. The results showed that the sensitivity of YG 95/168 was the highest, the sensitivity of Xintang 16 was the lowest, and the difference was significant. There were four new Xintai 22, Guitang 11, Guitang 21 and Yugu 94/128 The sensitivity of the varieties to 60% of the ring and the enemy WP was in the range of the above two, although the difference of the sensitivity to 60% of the ring and the enemy was not obvious, indicating that the sensitivity of 60% Sexuality is related to breed, and the sensitivity of a breed can not infer that the breed’s sensitivity is low or high. Therefore, to determine the sensitivity of sugarcane varieties to WP 60%, the test must be conducted.
