Field Treatments of Various Microbial Agents for Controlling Wheat Crown Rot
Wheat crown rot,an major soil-borne fungus disease primarily caused by Fusarium pseudograminearum,poses a significant threat to wheat production in China.It is prevalent in wheat producing areas.This study evaluated the comprehensive control efficacy of different seed coating and spray treatments at returning green stage and flowering stage,and the impact on yield at maturation stage.Evaluation of seed coating agents at seedling stage revealed that a mixture of Verticillium dahliae asp-f2 like(VDAL)and difenoconazole·fludioxonil·thiamethoxam significantly increased plant height,root height and seeding weight.Additionally,the incidence rate of crown rot was reduced by VDAL and Paeniocollus polymyua and Bacillus amyloliquefacien.The final results showed that the optimal treatment combination was found to be VDAL with difenoconazole·fludioxonil·thiamethoxam,resulting in a yield increase rate of 20.44％.Following closely were Paeniocollus polymyua and Bacillus amyloliquefacien,with yield increase rate exceeding 15％.
