Soya Bean Rust Control Test / Spray Application
[0364]Preparation of the Test Substances:
[0365]5 parts by weight of carboxamide of the formula (I), 142.4 parts by weight of acetone and 7.5 parts by weight of emulsifier (polyoxyethylene alkylphenyl ether) are mixed and adjusted with water to the desired concentration.
[0366]Test Method:
[0367]Soya beans (cultivar: Enrei) were cultivated in plastic containers having a diameter of 7.5 cm. In each case 3 containers, 6 ml of the test substance (preparation as described above) were sprayed onto the seedlings which had reached the 2.3 leaf stage. One day after spraying, the leaves were inoculated with an urediniospore suspension (1×105 urediniospores / ml) of Phakopsora pachyrhizi. 14 days after the inoculation, the degree of infection for each container was evaluated and the efficacy was calculated. The phytotoxicity was also monitored.
