“…Yield losses caused by seed-borne pathogens are found to be among 15 to 90% of untreated wheat seeds grown in fields [ 12 ]. Regarding that, numerous research have been conducted for the possibility of biological control of undesirable seed pathogens and increase of germination [ 13 , 14 ]. Moreover, there are various investigations in order to increase the areas in organic farming [ 15 ].…”

Seed treatments with zinc, boron, biostimulant Coveron and MIX (zinc + boron + Coveron) were applied to three lettuce and three celeriac cultivars. Seeds of three wheat cultivars were treated under laboratory conditions with Trichoderma harzianum and eight Bacillus spp. Seed germination, seedling growth, and the presence of the following pathogens were determined: Fusarium sp., Alternaria sp., Penicillium sp., and Mucor sp. The Coveron treatment was the most effective on lettuce seeds tested in the germination cabinet. Seed germination was higher by 4% than in the control. Alternatively, germination of seeds treated with boron in the greenhouse was higher by 12% than in the control. The Coveron treatment had the highest effect on the shoot length, which was greater by 0.7 and 2.1 cm in the germination cabinet and the greenhouse, respectively. This treatment was also the most effective on the root length. Zn, B, and MIX treatments increased celeriac seed germination by 14% in the germination cabinet. The Zn treatment was the most efficient on seeds tested in the greenhouse. The germination was higher by 15%. A significant cultivar × treatment interaction was determined in both observed species under both conditions. The maximum effect on wheat seed germination (8%) was achieved with the T. harzianum treatment in the Salazar cultivar. A significant interdependence (p ≤ 0.01 to p ≤ 0.001) was established between seed germination and the seedling growth. The interrelationship between seed germination and pathogens of all cultivars was negative.

Considering the importance of bean cultivation, the objective was to prove the effectiveness of the seed microbiolization method in the control of Sclerotinia sclerotiorum (Ss) on black bean seeds (cv. IPR Tuiuiú), inoculated by the water restriction method. The treatments were fungicide methyl thiophanate + fluazinam (350.0 g L-1 + 52.5 g L-1); Trichoderma asperellum BV-10 (1.0 x 1010 viable conidia mL-1); T. harzianum strain CCT 7589 (1 x 109 CFUs L-1); Bacillus subtilis BV-02 (minimum 3.0 x 109 CFU mL-1); B. amyloliquefaciens isolated BV03 (minimum 3.0 x 109 CFU L-1); Positive control (seeds exposed to Ss); Negative control (NC) + fungicide; NC + T. asperellum; NC + T. harzianum; NC + B. subtilis; NC + B. subtilis; and NC (PDA medium plus restricting). To verify the effects on germination, vigor, and the health of bean seeds, and seedling emergence in the field. Microbiolization with T. asperellum and T. harzianum, provides improvement in germination, vigor, and health, but is not superior to fungicide treatment. Bacillus subtilis and B. amyloliquefaciens, in seeds not inoculated with the pathogen, produce the best results for green and dry mass (g). These may be used in the integrated management of white bean mold.
