Plant disease control composition and plant disease control method

Abstract

A composition for controlling plant diseases comprising Paecilomyces fumosoroseus , and one or more nematicidal active ingredients selected from specific groups has an excellent controlling effect on plant diseases.

1 . A composition for controlling plant diseases comprising  Paecilomyces fumosoroseus , and one or more nematicidal active ingredients selected from the group consisting of Group (A1) and Group (A2).
 Group (A1): group consisting of aldicarb, thiodicarb, carbofuran, carbosulfan, dimethoate, fenamiphos, imicyafos, fensulfothion, terbufos, fosthiazate, dichlofenthion, isamidofos, fosthietan, isazofos, ethoprophos, cadusafos, phorate, thionazin, triazophos, diamidafos, phosphamidon, fluensulfone, MEP (fenitrothion), and fluopyram.   Group (A2): group consisting of Harpin protein,  Pasteuria nishizawae, Pasteuria penetrans, Pasteuria usgae, Myrothecium verrucaria, Burkholderia cepacia, Bacillus amyloliquefaciens, Bacillus firmus, Bacillus subtillis, Bacillus pumulis, Trichoderma harzianum, Verticillium chlamydosporum , and  Bacillus megaterium.      
     
     
         2 . The composition for controlling plant diseases according to  claim 1 , wherein the nematicidal active ingredients are one or more nematicidal active ingredients selected from Group (A1), and the ratio of the number of  Paecilomyces fumosoroseus  to the amount of the nematicidal active ingredients selected from Group (A1) is number of bacteria (CFU): amount (g)=10 7 :1 to 10 17 :1. 
     
     
         3 . The composition for controlling plant diseases according to  claim 1 , wherein the nematicidal active ingredients are one or more nematicidal active ingredients selected from Group (A2), and the ratio of the number of  Paecilomyces fumosoroseus  to the amount of the nematicidal active ingredients selected from Group (A2) is number of bacteria (CFU): number of bacteria (CFU)=1:10 5  to 10 5 :1. 
     
     
         4 . A method for controlling plant diseases comprising applying an effective amount of the composition for controlling plant diseases as defined in  claim 1  to a seed, a plant, or soil for cultivating a plant. 
     
     
         5 . A plant seed treated with an effective amount of the composition for controlling plant diseases as defined in  claim 1 . 
     
     
         6 . The composition for controlling plant diseases according to  claim 1 , wherein the plant disease is a soil-borne disease. 
     
     
         7 . The controlling method according to  claim 4 , wherein the plant disease is a soil-borne disease. 
     
     
         8 . The plant seed according to  claim 5 , wherein the plant disease is a soil-borne disease.
