“…On the other hand, several authors have reported that hypovirulent binucleate Rhizoctonia (HBNR) effectively controlled Rhizoctonia diseases in several plants (Burpee and Goulty 1984;Cardoso and Echandi 1987a;Ichielevich-Auster et al 1985;Villajuan-Abgona et al 1996;Pascual et al 2000). HBNR is also reported to control diseases caused by other pathogens such as damping-off disease caused by Pythium ultimum (Harris et al 1993) and black-shank disease caused by Phytopththora parasitica var nicotianae (Cartwright and Spurr 1998).…”

Four isolates of hypovirulent binucleate Rhizoctonia (HBNR), G1, L2, W1, and W7 were used for control of Fusarium wilt of tomato (FWT) caused by Fusarium oxysporum f. sp. lycopersici (FOL). HBNR isolates could significantly reduce disease severity (foliar symptoms and discoloration inside the stem) among five experiments under single and double applications. Reduction of disease severity by HBNR isolates, however, differed depending on HBNR isolates and treatments. Of four isolates, isolate HBNR W7 could significantly and consistently reduce (P ϭ 0.05) disease severity. Application of HBNR isolates significantly reduced (P ϭ 0.01) the number of colonyforming units of FOL in stems and roots of tomato. Among the HBNR isolates, G1, W1, and W7 could significantly increase (P ϭ 0.05) fresh weight of the plants (stems and leaves). These results indicate that isolates of HBNR have a greater potential as biocontrol agents against FWT. This is the first report of biocontrol of FWT by HBNR under greenhouse conditions.

“…With the popularize and extensive planting of compact hybrids, the heavy use of nitrogen fertilizer, the increase in planting density and the application of plastic film mulching in maize production, the BLSB developed and spread rapidly, which caused a decrease of production of 10 to 20% or even higher (Huang et al, 2007;Tang and Tao, 1991;Yan et al, 2008). Some chemical control and preventive treatment to BLSB of maize has been advanced according to the occurrence pattern and prevalence condition of the disease, while these treatments have the shortage to use, high in cost or effect less in same condition (Yan et al, 2008;Chen et al, 2011;Ascual et al, 2000;Cheng et al, 2008;Huang et al, 2006). Therefore, breeding of cultivar with high resistance to BLSB were thought to be the most effective and economy method, but the lacks of resistance material hinder the breeding progress (Huang et al, 2007).…”

Rhizoctonia solani causal agent of banded leaf and sheath blight (BLSB), is widely distributed in the South China and Southeast Asian in maize causing severe yield losses. In this study, we identified the disease resistance of 282 maize inbred lines to BLSB. The results showed that no immune and highly resistant germplasm was found and four moderately resistant inbred lines were identified. These four moderately resistant inbreds had good performance in grain yield, combining ability and a suitable growth period; they could be good donor of disease resistance gene to improve the other maize lines. The environments, R. solani isolate and the evaluation method were main factors that affect the evaluate results. In order to evaluate the disease resistance of maize lines to BLSB, environments beneficial to the disease, R. solani isolate have stronger pathogenic force, artificial infection and proper disease nurseries were necessary. The analysis on the disease resistant inbred lines from different heterosis groups showed that lack of resistance germplasm in SS array was more serious and it was more effective to seek resistance germplasm from the NSS array, especially from the PB and tropical maize germplasm.

“…A disease severity was rated from 0 to 4 described in methods after challenge inoculations with R. solani F-1 and S. rolfsii GUH-1 disease decline phenomenon was not observed with all the tested isolates, both pathogenic and hypovirulent isolates developed a high microbial biomass that positively contributed to the development of disease suppressive soils (Table 3). Isolates that have hypovirulent tendencies can possibly be used to induce suppressive soil in integrated pest management if judicially applied to the soil as reported by Villajuan et al (1996) and Pascual et al (2000). Their nonpathogenic nature, aggressive colonization ability and tolerance to a wide range of environmental conditions make these hypovirulent Rhizoctonia promising biocontrol agents (Muslim et al 2003).…”

Artificial suppression of radish damping-off disease was induced by repeated soil inoculations with Rhizoctonia solani, binucleate Rhizoctonia (BNR) and Sclerotium rolfsii in pot systems. Soils repeatedly inoculated with R. solani and BNR showed suppressive to disease caused by R. solani and S. rolfsii, while soils repeatedly inoculated with S. rolfsii were suppressive to disease caused by S. rolfsii but not by R. solani. Species of Trichoderma were consistently isolated from soils repeatedly inoculated with R. solani, BNR and S. rolfsii. These Trichoderma spp. accumulated selectively in relation to the fungal species that was repeatedly added to the soils. The ratios of the frequencies of T. viride, T. harzianum and T. hamatum were 5:2:2 and 8:5:2 in soils repeatedly inoculated with R. solani and BNR, respectively. In S. rolfsii-inoculated soils, T. koningii was predominantly isolated. T. viride, T. harzianum and T. hamatum isolates obtained from either R. solani or BNR after repeated additions to the soils suppressed radish damping-off disease caused after challenge inoculations with R. solani or S. rolfsii. Among the Trichoderma species, T. viride consistently yielded high levels of suppression. However, isolates of T. koningii obtained from S. rolfsii-infested soils suppressed disease caused by S. rolfsii but failed to suppress disease caused by R. solani. Generally, the species of Trichoderma accumulated in a selective pattern that was closely related to the species of fungal pathogen used to induce the suppressive soil.
