“…Koch (1999) tested five commercial formulations of antagonistic fungi in the biocontrol of cucumber damping‐off in the greenhouse but only one product gave significant control. However, others have reported success in controlling P. ultimum with either Trichoderma (Cliquet and Scheffer 1996; Naseby et al . 2000) or Gliocladium (Koch 1999).…”

Aims: Five bacterial strains belonging to Bacillus subtilis, Pseudomonas fluorescens and Ps. corrugata and two fungal strains belonging to Trichoderma viride and Gliocladium virens were evaluated for their efficacy in controlling sugar beet and cucumber damping‐off caused by Pythium ultimum. Methods and Results: The in vitro antagonistic activity of bacteria against various Pythium spp. was evaluated with dual cultures in various media. Pseudomonas strains inhibited the pathogen better than Bacillus strains. To identify potentially useful antagonist combinations, dual compatibility of antagonists was also evaluated, based on growth in two liquid media containing substrate previously used by other antagonists. Four pairs of bacteria were selected. Sugar beet damping‐off biocontrol was attempted with bacterial seed treatments (individually and in pairs). Cucumber damping‐off biocontrol was attempted with bacterial seed treatments and bacterial and fungal compost treatments. In sugar beet, satisfactory biocontrol was only achieved with Pseudomonas antagonists. Antagonist combinations did not show any superior biocontrol ability to individual antagonists and compatibility of bacteria in vitro did not correlate with compatibility in vivo. Bacterial seed treatments and fungal compost treatments failed to control cucumber damping‐off. Better biocontrol in cucumber was achieved when bacterial antagonists were applied by drenching or by coating seed with bacteria in a peat carrier. Conclusions: Pseudomonas antagonists were superior to Bacillus antagonists in controlling damping‐off in cucumber and sugar beet. Pseudomonas peat inocula maintained a good shelf‐life 2 years after preparation. Significance and Impact of the Study: Pseudomonas peat formulations have the potential for development into commercial biopesticides.

“…Their consistency and efficiency of protection (22–68%) is comparable to, or better than, other biological treatments of cucumber. Cliquet and Scheffer (1996) reported protection of cucumber seedlings by 22% with a precommercial Trichoderma sp. seed treatment.…”

“…More recently, biological control of damping-off in cucumber and radish, caused by P. ultimum and Rhizoctonia solani, was obtained using Trichoderma spp. applied to seeds as an industrial filmcoating (Cliquet & Scheffer, 1996). However, there appear to be no reports of commercial seedcoating of fungal biological control agents for control of S. sclerotiorum.…”

Conidia of the biological control agent, Coniothyrium minitans, were applied to uninfected and S. sclerotiorum-infected sunflower seeds and to sclerotia of two isolates of S. sclerotiorum by polymer filmcoating, using a fluidised-bed seed treater. Rates of 5 × 10 6 and 7-14 × 10 6 conidia per g of seed and sclerotia were obtained, respectively. The activity of C. minitans was compared to treatments with the fungicides thiram þ fenpropimorph and iprodione. In agar plate tests, C. minitans increased seed germination and decreased recovery of S. sclerotiorum from S. sclerotiorum-infected seeds. However, in seedling tests carried out in a potting compost-soil mix with S. sclerotiorum-infected seeds, C. minitans failed to increase survival of seedlings. A high and low rate of thiram þ fenpropimorph and a high rate of iprodione film-coated onto S. sclerotiorum-infected seeds gave consistently better results than C. minitans in these tests. The film-coating process slightly decreased the germination of C. minitans conidia recovered from sunflower seeds and sclerotia of S. sclerotiorum, but after storage for 1 year at 10ЊC C. minitans grew from more than 97% of seed and sclerotia, and the number of colony forming-units per g seed or sclerotia had declined by less than 1 log 10 unit. In agar plate tests, all fungicide treatments were more effective than C. minitans in delaying myceligenic germination of film-coated sclerotia, although for sclerotia of isolate JN1, all film-coatings were effective in decreasing the weight of sclerotia subsequently produced. With isolate SB, only the C. minitans treatment reduced subsequent sclerotial production. In glasshouse and field pot bioassays with sclerotia buried in soil for 20 and 34 weeks, respectively, C. minitans completely suppressed apothecial production and no sclerotia were recovered from the C. minitans treatment pots. C. minitans spread to infect sclerotia in other treatment pots. In these bioassays, both fungicides were less effective than C. minitans, even though apothecial production was almost completely inhibited and less than 10% of sclerotia were recovered.

Efficient application of Trichoderma viride on soybean [Glycine max (L.) Merrill] seed using thin layer polymer coating

Soybean crop is very sensitive to change in climate and suffers from vagaries of climate. The productivity thus gets affected in different years due to the influence of climatic condition, incidence of diseases and insects. Trichoderma sp. is considered as a potential biocontrol and growth promoting agents for many crop plants. Trichoderma spp. is generally being applied to the soil and seed as talcum powder form. Though powder formulations may be applied directly to seeds at the rate of 5g/kg seed, the effectiveness of Trichoderma seed treatment is lost due to poor adhesion on the smooth seed coat surface of soybean. Thus, it was targeted to achieve maximum benefit by Trichoderma seed treatment mediated through polymer coating. Two soybean cultivars were treated with Trichoderma viride with different formulation namely Trichoderma culture solution with polymer, Trichoderma culture talc with polymer, Trichoderma culture talc powder dry dressing. Endophytic growth of Trichoderma viride in root, stem and leaf was studied by agar plate method at 27±10C for seven days. The percentage of plants with Trichoderma endophytic growth was 97-100 per cent in plants from seeds treated with Trichoderma with polymer as compared to 37-45 per cent in plants from seeds treated with Trichoderma talc powder dry dressing. Control plants did not show any endophytic growth of Trichoderma. Significant increase in plant height was observed due to endophytic growth of Trichoderma. 24 per cent yield advantage was observed due to Trichoderma culture solution treatment with polymer. Seedling mortality due to collar rot (0.61%) and disease incidence of Myrothecium Leaf Spot, Anthracnose and Rhizoctonia Arial Blight (0.34%) was significantly lower than control (9.8% and 9.169%). Proper application of Trichoderma viride on soybean seed through polymer coating has significant potential to reduce diseases and to improve plant growth and seed yield.
