ABSTRACT New technologies are being incorporated to the seed treatment process, such as the use of products on industrial scale. This study aimed at evaluating the seed quality of wheat cultivars, as well as the influence of the seed treatment method on the establishment and yield of this crop. Seeds of the cultivars Jadeite 11, Quartzo and Tec Frontale were treated with the Spectro® fungicide (difenoconazole - 200 mL 100 kg-1 of seeds), Cruiser Opti® insecticide (thiamethoxam + lambda-cyhalothrin - 200 mL 100 kg-1 of seeds) and Polifix G4 polymer (100 mL 100 kg-1 of seeds). A completely randomized design, with four replicates, was used. The treatments consisted of industrial treatment, on farm treatment with the same products and control. Germination, first germination count and moisture content tests were carried out immediately after the seed treatment and at 30, 90 and 150 days of storage. Seedling emergence in beds was evaluated at 30, 60 and 120 days of storage. Under a randomized block design, seedling emergence and grain yield were evaluated in the field in two sowing seasons. The conventional or industrial seed treatment methods do not reduce the physiological quality and emergence of high-vigor seeds stored for 150 days, under controlled conditions of temperature and humidity. The conventional or industrial seed treatment with diphenoconazole + thiamethoxam + lambda-cyhalothrin + polymer does not increase the wheat crop plant stand and grain yield.

Foliar Fungicide

The oat crop is of great economic importance and seed production depends on several factors (biotic and abiotic) that can alter its quality. Thus, the study aimed to evaluate the physiological quality of oat seeds produced with and without application of foliar fungicide in contrasting environments. The experimental design was a randomized block design in a factorial 6x2 (cultivar x fungicide) for each site, with four replications. The physiological quality of seeds was evaluated by grain yield, germination, first count, accelerated aging, moisture content after accelerated aging, seedling length, seedling dry weight, electrical conductivity and seedling emergence in field. Data were subjected to joint and individual analysis of variance, and means were compared by Tukey’s test at 5%. Grain yield in Mauá da Serra is superior to Londrina, Parana State - Brazil, but the seed quality is lower, although all cultivars have shown germination above 90% in the two cultivation sites. Cultivars FAEM 6 DILMASUL and UPFA OURO showed no disease, indicating possible resistance. The application of the product has a beneficial effect on seed germination and vigor, even in the absence of disease.

Abstract: The objective of this work was to evaluate the effect of different grain sizes and treatments in the physiological quality of seeds and performance of soybean cultures. The object of analysis were seeds from the cultivars Monsoy 5730 IPRO and Monsoy 5947 IPRO, sized 5.5 and 6.5 mm. The industrial seed treatment was carried out in lot equipment, with the products cyantraniliprole, thiamethoxam, metalaxyl, thiabendazole, and a combination of fludioxonil + polymer + talc. The conventional treatment was performed with the products cyantraniliprole, thiamethoxam, metalaxyl, thiabendazole, and fludioxonil. Part of the seeds was kept untreated (control). The experiment used a randomized block design, with four replications. The parameters assessed include the moisture content measurement, seed coating, germination, first germination count, field emergence, survival rate, and grain yield (right after the seed treatment and after 45 days of storage). The industrial treatment method produced a better seed coating. As for seed size, it had no effect on quality or grain yield. Last, the treated seeds presented the best results for emergence in field, while the industrial treatment achieved the highest productivity.

Abstract: Some desiccation techniques for harvesting wheat may affect seed quality. The objective of this study was to evaluate the effect of different desiccant herbicides applied to the wheat crop and their effects on the production and seed quality. The experiment was conducted with cultivar COODETEC 150 (CD 150) in two sites in Palotina (Paraná state, Brazil) with a randomized block design consisting of 7 treatments (desiccation herbicides) and 4 replications. Desiccation was realized when 50% of the plants were in stage 80 with seeds in powdery or mass consistency. The variables analyzed were percentage of moisture content after harvest, Yield, hectoliter weight, mass of 100 seeds, vigor, germination, fresh mass of seedlings, dry mass of seedlings and root length. The herbicides carfentrazone-ethyl and clethodim were the ones that promoted greatest reduction in vigor. The herbicide paraquat caused reduction in seedling length. There was a reduction in the mass of 100 seeds for glufosinate-ammonium, clethodim, diquat and carfentrazone-ethyl. Glufosinate-ammonium, paraquat, glyphosate, clethodim and diquat caused reduction in yield. Desiccation of Cultivar CD 150 at stage 80 is not recommended, since plant Yield and physiological seed parameters were adversely affected by herbicides.

The aim of this study was to analyze soybean seed physiological quality after being subjected to various mixtures of pesticides via industrial seed treatment. The experiment was performed at the seed laboratory of the company BioGrow, located at São Paulo-SP, using soybean seeds cultivar NS 6700 IPRO which were subjected to 11 different treatments. Seed treatment was carried out using a treater Momesso, model L5-K, calibrated to apply a spray volume of 0.5 L 100 kg-1 of seeds in which the volume of each treatment was adjusted using distilled water. After treatment, seeds were spread over plastic strays for drying for a period of 24 hours under environmental conditions. Once dry, seeds were packed in paper bags and stored for 0 (control), 45, 90, 135 and 180 days, under uncontrolled conditions of temperature and relative humidity, when seed physiological quality was evaluated using the following tests: germination, accelerated aging, seedling emergence, speed of emergence index and speed of emergence. Soybean industrial seed treatment before storage for up to 180 days is practicable using the mixtures of pesticides tested for storing seeds under environmental conditions. All treatments tested contribute to the maintenance of seed quality throughout storage.

Abstract: In the sowing process, the technique of seed treatment may assist in maintaining crop yield potential. This present study aimed to assess how wheat seed treatment with two different sources of micronutrients, combined with fungicide + insecticide protective treatment and coating with liquid polymer, may impact its vegetative development and grain production. Wheat seeds of cultivar Tec Vigore were subjected to three different treatments using micronutrient containing zinc: no micronutrient, micronutrient 1 (1% Mn, 0.1% Mo, 10% Zn); micronutrient 2 (0.3% B, 0.3% Co; 3% Zn), where micronutrient treatments were combined with different protective treatments used for seed treatment: untreated seeds, polymer (Color seed He), fungicide (Vitavax® Thiram 200 SC) + insecticide (Cruiser® 350 FS) and combination of polymer + fungicide + insecticide. We assessed parameters related to crop development, such as seedling emergence, dry matter of root and shoot, tillers, and for physiological maturity, we assessed grain yield and hectoliter weight. Seed treatment with micronutrients, polymer, fungicide + insecticide and combinations thereof does not reduce emergence and may increase seedling stand, but without influencing wheat grain yield.

The objectives of this study were to evaluate the effect of the chemical composition of soybean seeds and the efficiency of seed mineral supplementation on physiological quality and field performance. Two seed lots (high and low levels of mineral nutrition), with or without supplemental macro- and micronutrients, of three soybean cultivars (BMX Potência RR, BMX Turbo RR, and BMX Magna RR) were used. For the laboratory experiment, a completely randomized design with four replications was used. To evaluate the physiological quality of the seeds, the water content, first count, germination, 1,000-seed weight, and length and dry weight of the seedling were determined. For the field experiment, a randomized block design with four replications was used, and seedling emergence and grain yield were evaluated. Seeds with higher nutrient content produced seedlings of greater vigor and higher grain yield for all of the cultivars studied. The use of mineral supplementation in seed lots with low nutrient content resulted in greater vigor under laboratory conditions. The increase in grain yield after mineral supplementation depends on the quality of the seed lot.

The objectives of this study were to evaluate the efficiency of fungicides for pea seed treatment against damping-off caused by Rhizoctonia solani and to verify their effects on physiological seed quality. 'Mikado' pea seeds were treated with the following fungicides: Carbendazim, Carbendazim + Thiram, Captan, Iprodione, Iprodione + Thiram, Metalaxyl-M + Fludioxonil, Pencycuron, Procymidone and Tolyfluanid. Control seeds were treated with deionized water. Physiological seed quality was evaluated with the following tests: germination, first count, accelerated aging and electrical conductivity. Seeds were sown in soil inoculated and no inoculated with R. solani. The experimental design was completely random with four replications. Seedling emergence was reduced in inoculated soil and the best treatments for R. solani control were Carbendazim, Pencycuron, Iprodione and Carbendazim + Thiram. Captan reduced seed physiological quality in both the laboratory and field.

The industrial treatment of seeds has favored the development of new technologies such as the use of dry powder. It has made application of spray volumes higher than those used in the conventional treatment. Therefore, this study aimed to assess the effect of industrial treatments at different spray volumes with and without application of dry powder on physiological quality of soybean seeds. A completely randomized experimental design was performed with four replications in a 5 x 2 factorial arrangement for cultivars BRS 359 RR and BRS 284. The factors were five spray volumes (0, 600, 1200, 1800 and 2400 mL. 100 kg-1) with and without the application of dry powder. The products used to obtain the volumes were fungicides (carbendazim + thiram); insecticides (imidacloprid + thiodicarb); nematicide (abamectin); micronutrients (cobalt, molybdenum and zinc); polymer (peridiam); biostimulant (kinetin + gibberellic acid + 4-indol-3-ylbutyric acid) and inoculant (Bradyrhizobium japonicum). The physiological quality of the seeds was determined by the following assessments: germination, first count of germination test, seedling emergence in sand, emergence speed index, and total length of the seedling shoot and root. The results showed that increased spray volume associated with the application of dry powder in seed treatment reduced the physiological quality of soybean seeds, and spray volumes up to 1200 mL 100 kg-1 in seed treatment without the application of dry powder do not impact the emergence and establishment of soybean seedlings.

The physiological quality of bean seeds is influenced by the production environment and management practices employed during cultivation. The objective of this study was to evaluate the productivity and physiological quality of bean seeds after desiccant applications at different times at pre-harvest. A randomized block design was used, with a factorial (3x3) + 1 arrangement, where the application of three desiccants was tested: glyphosate (960 g a.i. ha-1), paraquat dichloride (240 g a.i. ha-1) and glufosinate ammonium (400 g a.i. ha-1) + mineral oil, applied three times (days after flowering - DAF), and a control without herbicide in four replications. Seed quality was determined by the following tests: germination, first count, seedling emergence speed rate, accelerated aging, electrical conductivity and seedling dry biomass. Seed yield was not influenced by either herbicides or time of application. Regardless of time of application, the lowest percentage of normal seedlings after the germination, first count and accelerated aging tests was observed in seeds desiccated with the herbicide glufosinate ammonium. The herbicide glyphosate reduces seedling vigor. The times of application of the product paraquat dichloride did not affect the germination and vigor of bean seeds.

Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.
