use of succinate dehydrogenase inhibitors to increase the resistance of plants or parts of plants against abiotic stress.

摘要

Use of a succinate dehydrogenase inhibitor for increasing resistance of a plant against abiotic stress factors, is claimed. ACTIVITY : Plant Protectant. The plant protectant activity of the inhibitor was tested on Brassica napus, which was grown on a sandy clay under greenhouse conditions for 2-3 weeks. The plants were treated with bixafen by spraying at 250 g/hectare, and exposed to drought stress condition by heating a test chamber at 26[deg] C/18[deg] C during day/night respectively and then the chamber was brought back to normal temperature after one week, and the plants were allowed for a recovery period of 7 days. The result showed that the plants treated with bixafen exhibited a high tolerance against the drought stress condition with the efficiency of up to 15%. MECHANISM OF ACTION : Succinate dehydrogenase inhibitor.
