“…Although primary goal of seed treatment is to protect the seeds from soil pathogens and insect pests, prolonged germination and emergence, as a result of applied pesticides, exposes seed to a longer infestation period. Therefore, according to Vujošević et al (2017), in order to provide the fast and uniform emergence under different conditions, further examination of the response of different genotypes to the specific seed treatment should be performed.…”

Sunflower seed treatments are inevitable measure that ensures protection from soil-dwelling insects and pathogens at the first stages of plant development. Due to the ban of neonicotinoid based insecticides for the sunflower seed treatments, new registered preparations are put to test. The aim of this work was to assess the efficacy of currently registered insecticides against the wireworms (observed in field emergence and percent of damaged plants) and their effect on yield traits (yield, oil content and 1,000-seed weight) of the sunflower hybrids (Sumo 2 OR, Oliva and Novak) in comparison to previously used neonicotinoids. Seeds were treated with different pesticidal combinations: metalaxyl-m, metalaxyl-m + bifenthrine, metalaxyl-m + thiacloprid, metalaxyl-m + thiametoxam, and metalaxyl-m + imidacloprid. Twoway ANOVA and Duncan's multiple range tests were performed. Field emergence was not influenced by the treatment. Sumo 2 OR and Oliva emergence did not differ significantly among the treatments (78.3-88.3%; 83.0-91.3%, respectively), but for Novak it was significantly lower (79.3%) when treated with metalaxyl-m. The lowest percent of damaged plants was in the treatment with metalaxyl-m + thiametoxam (1.1-2.4%). However, it did not differ significantly among other treatments (2.4-3.9%), regardless on the hybrid. Novak had the highest average yield (3,938.1 kg/ha), followed by Sumo 2 OR (3,566.1 kg/ha), and Oliva (3,199.8 kg/ha), regardless on the applied seed treatments. The highest 1,000-seed weight was measured for Oliva. Given indicates that currently registered insecticides for the seed treatment of sunflower, such as Sonido and Semafor, can be adequate substitute to the banned neonicotinoids like Cruiser and Gaucho.

“…Čanak et al 2016found that seed priming treatments had more improving effects on the studied maze seed and seedling traits under suboptimal than under optimal conditions. Vujošević et al (2017) concluded that there were differences in response of maize genotypes to applied pesticide treatments on seed, as well as to a specific treatment at optimal and suboptimal temperatures.…”

The objectives of this study were to determine the effects of different priming treatments and genotypes on maize germination and early seedling growth traits, as well as to examine the associations among these traits. In addition, the application of genotype by trait biplot methodology in this type of analysis was evaluated. Seed priming treatment was conducted on ten maize inbred lines by soaking seeds in water (hydropriming) or in 0.5% KNO3 solution. Seed was sown in sterile moistened sand and placed at suboptimal (15°C) and optimal temperature (25°C) for seven days. After that, seedling length and seedling weight were measured, final germination, time to 50% emergence and vigour index were calculated. The results showed that seed priming can improve seedling growth traits at both temperatures. There are differences in genotype responses to various seed priming solutions. The observed differences represent useful information for the selection of adapted maize inbred line and adjustment of priming treatment for sowing in different temperature conditions. This study showed that biplot could easily be used for assessing the effect of seed priming, or some other treatment, on seedling growth traits. Moreover, it can be used to understand the associations among the seedling growth traits.
