“…Nematicidal formulations based on the active ingredient abamectin (avermectins) have been developed specifically for seed applications. The efficiency of abamectin was first reported in the control of M. incognita in cotton (MONFORT et al, 2006), tomato (FASKE;, and melon (MOREIRA et al, 2004); when applied at relatively low doses in the seed treatment, the active ingredient interacts with the tegument and interferes with the nematode population around it (FASKE;BESSI et al, 2010;CORTE et al, 2014). Other studies, however, indicate that seed treatment with nematicides offers good prospects when integrated with other measures within phytonematode management (FAVORETTO et al, 2010;STEFFEN et al, 2011).…”

“…Faske and Starr (2007) also explained that abamectin is concentrated in the seed tegument, and as the roots develop beyond this protective region, they are exposed to nematode attack. Moreover, seed treatment promotes greater root system development, which becomes a very efficient nutritional source for nematodes, resulting in increased nematode populations at the end of the crop cycle (BESSI et al, 2010). However, the control of the nematode population in the initial phase of the crop is fundamental to ensure protection and realization of the yield potential of the crop (OLIVEIRA et al, 1999;GALBIERI et al, 2007).…”

The objective of this study was to evaluate the efficacy of the active ingredient abamectin, either in isolation or in combination with fungicides and insecticides formulated for the industrial seed treatment, on the population of Meloidogyne javanica, tested under greenhouse and in vitro conditions. In both tests, the combination of the following treatments was assessed: abamectin; thiamethoxam; fludioxonil + metalaxyl-M + thiabendazole. Water was used as control for the in vitro assay, whereas under greenhouse conditions, controls were inoculated and not inoculated with M. javanica. The tests were conducted in a completely randomized design with six (in vitro) and ten (greenhouse) replicates. For in vitro studies the effect on hatching, motility, and mortality of juveniles of M. javanica was evaluated. Under greenhouse conditions, the soybean 'BRS 133' seeds were treated, and at 15, 30, and 60 days after inoculation (DAI) with M. javanica, plant measurements were recorded. The penetration of second stage juveniles (J2) was also evaluated at 15 DAI. At 30 DAI, galls, egg masses, nematodes/g of root, and final population were evaluated. At 60 DAI, the final population of nematodes in the roots was quantified. The treatments containing abamectin were the most effective in diminishing the hatching of juveniles. All treatments had an effect on nematode motility when compared to the control, and in the treatment containing only abamectin, total juvenile mortality was observed. In greenhouse conditions, at 15 DAI, the treated soybean plants had the highest root mass and shoot length, differing statistically from the inoculated control. All treatments reduced the number of nematodes per gram of root, differing from the control. At 30 DAI, treatment efficiency was observed in reducing the final population of M. javanica, particularly the treatments using abamectin, and abamectin + thiamethoxam + fludioxonil + metalaxyl-M + thiabendazole. However, at 60 DAI, the effect of the treatments on the population of M. javanica did not persist. Key words: Hatching. Mortality. Motility. Nematicide. Root-knot nematode.

Como controle utilizou-se água para o ensaio in vitro, e testemunhas inoculada e não inoculada com M. javanica, em casa de vegetação.

“…Among the naturally occurring bio nematicides are avermectins. These are a family of 16 membered macrocyclic lactones produced by the soil microorganism, Streptomyces avermitilis (Bessi et al, 2010). These compounds are important tools in animal health and crop protection, the major component of the fermentation being avermectin B1 (Abamectin) (Rehman, 2009).…”

“…These compounds are important tools in animal health and crop protection, the major component of the fermentation being avermectin B1 (Abamectin) (Rehman, 2009). A number of success cases in abamectin controlling nematodes have been reported in tomatoes and cotton seed treatments (Becker, 1999;Monfort et al, 2006;Faske and Starr, 2006;Rehman, 2009;Alfonso et al, 2009: Bessi et al, 2010DeBeer, 2010). Chen et al (2006) demonstrated the enhancement of a bio agent Pochonia in reducing nematode damage in vines with a resultant increase in plant dry weight and height.…”

The efficacy of different rates of abamectin for the control of root knot nematodes in tobacco soil-based seed beds was evaluated in this study. Different incorporation methods of abamectin in the soil were also evaluated. A combination of 45 ml worked into the soil to a depth of 20 cm using hoes was effective in controlling root knot nematodes. The efficacy was comparable (p = 0.05) to methyl bromide and 1.3 D. The other treatments evaluated did not give control and were comparable to the untreated control. Based on the results, abamectin can be a suitable replacement for methyl bromide for root knot nematode management in the tobacco seedbed.

“…Seed treatment with nematicides has also been suggested to control P. brachyurus. According to Bessi et al [44], seed treatment with nematicides can be an effective control method for this nematode, since it avoids damage in early stages of plant development, which stimulates the development of roots and minimizes the effect in case of drought stress. Several studies reported the effect of the seed treatment in reducing P. brachyurus population level in soybean [45].…”

Plant-parasitic nematodes are one of the limiting factors for soybean production worldwide. Overall, plant-parasitic nematodes alone cause an estimated annual crop loss of $78 billion worldwide and an average crop yield loss of 10-15%. This imposes a challenge to sustainable production of food worldwide, since there has been increasing demand for food supply and food security. Unsustainable cropping production systems with monocultures, intensive use of soils and expansion of crops to newly opened areas have intensified problems associated with new pests and diseases. Thus, finding and applying sustainable methods to control diseases associated with soybean are in current need. Over hundred nematode species, comprising fifty genera, have been reported in association with soybean. Of these, the root-knot nematode Meloidogyne spp., cyst nematode Heterodera glycines, lesion nematode Pratylenchus brachyurus and the reniform nematode Rotylenchulus reniformis are major nematode species limiting soybean production. Here, we report an up-to-date literature review on the biology, symptoms, damage and control methods used for these nematodes species. Additionally, unusual and emergent nematode species affecting soybean are discussed.
