Rhizoctonia, inoculation, transition zone


Turf quality characteristics and large patch incidence of ten selected experimental zoysiagrass genotypes were evaluated during the 2018–2019 growing season in Manhattan, KS, and establishment rate of the same ten was evaluated in Olathe, KS. Although plots were inoculated with Rhizoctonia solani (AG 2-2 LP) in September 2018 in Manhattan, no large patch occurred. However, the genotypes showed vari­ability in turf performance measured by turf quality, spring greenup, fall color reten­tion, and genetic color. In Olathe, KS, at Shadow Glen Golf Club, the ten genotypes were planted on June 17, 2019. The range in visual ground coverage on September 27, 2019, was 63.3 to 92.7%.
