Seed treatment with beneficial microbes or biocontrol agents is called biological seed treatment. Vegetable seed quality includes the physical, pathological, genetic and physiological that leads to successful crop establishment and yield . Use of BCA’s as seed treatments can play an important role in most aspects of seed quality, and be of particular benefit for improved seeding growth under stressful conditions. It not only improve the quality of seed but also protect seed from different seed borne diseases and make the seed healthy.

Seed treatment with growth regulators, especially salicylic acid, is a promising alternative to the seed industry because it is an important inducer of resistance to diseases and pests, as well as acting significantly on quality and seed yield. The objective of this study was to evaluate the performance of rice seed treated with different concentrations of salicylic acid, as well as assess the crop yield and seed quality. The treatments consisted of increasing levels of 0, 50, 100, 150 and 200 mg.L-1 salicylic acid. To this was prepared a stock solution of salicylic acid and the highest concentration by successive dilution in distilled water, the other concentrations were obtained. The physiological quality of seeds produced was treated and evaluated by tests of vigor and germination, and after harvest were evaluated seed yield. It follows that treatment of rice seeds with salicylic acid concentrations up to 130 mg.L-1 at a dose of 2 mL.kg-1 seed does not affect the germination and affects the strength, however provides substantial increases in the yield of seeds. The seed treatment with salicylic acid has no influence on seed quality produced.

Soybean seed treatment contributes to the maintenance of seed quality, but the effect of commercial formulations and chemical products on the effectiveness of the electrical conductivity test based on electrolyte leaching has been frequently questioned. This study aimed to verify the interference of the chemical seed treatment of two soybean cultivars on the effectiveness of the electrical conductivity test in evaluating the vigor of freshly treated and stored seeds. The experimental design was completely randomized, consisting of seven seed treatments and two evaluation periods (0 and 60 days after storage), with four replications. The used seed treatments consisted of 1) fipronil + pyraclostrobin + thiophanate-methyl, 2) imidacloprid + thiodicarb + carbendazim + thiram, 3) abamectin + thiamethoxan + fludioxonil + mefenoxam + thiabendazole, 4) carbendazim + thiram, 5) fludioxonil + mefenoxam + thiabendazole, 6) carboxin + thiram, and 7) control (no treatment). The cultivars were BRS 360 RR and BRS 284, which were analyzed separately. Germination, accelerated aging, emergence, and electrical conductivity tests were carried out. No differences were detected between the control and chemical treatments performed on seeds of the two freshly treated soybean cultivars regarding germination, accelerated aging, and emergence tests. The germination test stood out after storage with the cultivar BRS 360 RR, showing the maintenance of germination potential for seeds treated with carbendazim + thiram and the control treatment. Therefore, the chemical treatment of soybean seeds interferes with the result of the electrical conductivity test. The electrical conductivity test is effective in segregating seed lots in terms of vigor level. The electrical conductivity test correlates with the other vigor tests used to identify the reduction in the physiological seed quality with storage.

Disease management is an important step in any crop establishment system. Emergence of field-seeded crops may take several weeks for many species and represents a vulnerable stage of plant growth. This paper considers various biological, chemical, and physical seed treatments for improved seed performance. The role of seed quality and cultural practices in seedling establishment also is reviewed. Multidisciplinary approaches to improving horticultural crop establishment are promising.

Abstract: Fungi are considered as the most important among pathogens due to the higher number of species and to the damage caused both in yield and in seed quality. Thus, aimed to verify the effect of fungicide and insecticide treatment on sanitary quality and physiological performance of soybean seeds before and after storage. Seeds from cultivars NS 7494, NS 8693 and NS 7338 IPRO were used, which were analyzed separately by a completely randomized design in a 3 x 6 factorial design, being three chemical treatment applications: 1) treated and evaluated; 2) treated, stored and evaluated; 3) stored, treated and evaluated; and six mixtures of fungicides and insecticides: (Imidacloprido + Tiocarbe) + (Carbendazim + Tiram), (Imidacloprido + Tiocarbe) + (Metalaxil-M + Fludioxonil), Thiamethoxam + (Carbendazim + Tiram), Thiamethoxam + (Metalaxil-M + Fludioxonil), (Fipronil + Piraclostrobina + Metil-tiofanato) and the control, which was added only water. The healthy test, germination, cold and accelerated aging tests were evaluated. Seed treatment products require at least two months to be effective in controlling Penicillium spp. and Fusarium spp. The mixtures containing Carbendazim + Tiram in its composition are efficient in the control of pathogens regardless of the application time of products.

Background: Foxtail millet is considered as nutri-cereal and source of food, feed and fodder. Though it is grown in marginal conditions it can give the best production with the proper nutrient management for its cultivation. The objective of study was to identify the suitable seed quality enhancement method to increase grain yield of foxtail millet. Methods: During kharif 2017 and 2018 on black cotton soils at Regional Agricultural Research Station, Nandyal, the experiment was conducted in field and laboratory with split plot design with four nitrogen doses as main plots such as N1- control, N2- 125 kg neem+1250 kg vermi compost /ha, N3- 50 kg urea+50 kg super phosphate and 50 kg murate of potash /ha + top dressing urea at 3-4 weeks after transplanting + 2% borax spray, N4- N2 + N3 and four pre sowing seed treatments as sub plots. The treatments were P1- control, P2- soaking in water for 8 hours by adopting seed to solution of 1:1 ratio,P3-seed soaking with 2% KH2PO4 for 8 hours by adopting seed to solution of 1:1 ratio, P4-seed treatment with 20% liquid Pseudomonas fluorescens. After pre sowing seed treatment, seed were sown in field with different nitrogen doses. Result: Results revealed that application of 50 kg urea+ 50 kg super phosphate and 50 kg murate of potash/ha + top dressing urea at 3-4 weeks after transplanting + 2% borax spray recorded significantly higher seed yield (3148 kg/ha) and in pre sowing seed treatment with 20% liquid Pseudomonas fluorescens (3019 kg/ha) than other treatments.

ABSTRACT The use of an appropriate method that accurately expresses physiological seed quality and minimizes possible phytotoxicity by chemical products in laboratory testing with soybean seeds is relevant. The objective of this work was to evaluate the influence and infer the method adequacy for the representative evaluation of physiological quality of soybean seeds treated with phytosanitary products. Two experiments were carried out in a completely randomized design, with trial 1 in a 9×5 factorial scheme involving nine seed treatments, including fungicides and insecticides, and solutions with five osmotic potentials (0, -0.25, -0.5, -0.75 and -1.0 MPa) for wetting a paper substrate in a germination experiment, with evaluation of the normal seedlings at five and eight days after sowing. The second experiment consisted of a 9×7 factorial, with nine seed treatments and seven methods for germination evaluation at 5 days (between paper - BP, between sand - BS, between paper with water restriction - BPWR, between paper with preconditioning - BPC, sand between paper - SBP and vermiculite between paper - VBP). Treatments with insecticides affect seedling germination and evaluation, with greater phytotoxicity in relation to fungicides. Methods with readily available water led to greater phytotoxicity than methods with low water availability. For soybean germination evaluation of seeds treated with phytosanitary products, the BPC, SBP and VBP methods were optimal.
