13. Dinâmica do Fomesafen no solo e impacto de Tiametoxam e Fomesafen sobre três espécies de macrófitas aquáticas / Dynamics of fomesafen in soil and impact of thiamethoxam and fomesafen on three freshwater macrophytes
Pesticides are very important to the modern agriculture. However, nowadays, with their increasing use, sometimes indiscriminately, there is also an increasing concern about their soil and water contamination. Fomesafen (herbicide) and thiamethoxam (insecticide) are organic compounds with very different physicochemical properties, but both are used in crops o

14. DANOS DO PERCEVEJO-BARRIGA-VERDE Dichelops melacanthus (DALLAS, 1851) (HEMIPTERA: PENTATOMIDAE) NA CULTURA DO MILHO / GREEN BELLY STINK BUG Dichelops melacanthus (DALLAS, 1851) (HEMIPTERA: PENTATOMIDAE) DAMAGES IN MAIZE CROP
The research objective was to evaluate the damage caused by D. melacanthus in the initial phase of the maize crop. Two field trials were conducted in Rondonópolis, Mato Grosso, and two greenhouse trials occurred in Santa Maria, Rio Grande do Sul. In all experiments artificial infestation of cages was done using laboratory reared stink bugs. In all experimen

15. Effects of carbosulfan on pineapple (Ananas comosus (L.) Merr.) growth.
The effect of the systemic insecticide carbosulfan on the growth of pineapple, transplanted from in vitro cultures, was observed in a greenhouse experiment. Three doses of carbosulfan (10,25 and 50 ppm) were applied along with a control (no insecticide). the plants were harvested at 30, 60, 90, 120 and 150 days after being transplanted. The everage leaf leng

16. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

17. Bioatividade de nanoformulações de nim e extratos de outras Meliaceae e a sua interação com agentes de controle biológico visando ao controle de Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) / Bioactivity of neem nanoformulations and extracts of other Meliaceae and their interactions with biological control agents aiming to control Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
A bioatividade de nanoformulações de nim e de extratos de outras Meliaceae foi avaliada, em tomateiro, em laboratório e em casa de vegetação, visando ao controle de Tuta absoluta (Meyrick). Incialmente foram testadas 22 nanoformulações (incluindo nanocápsulas e nanoesferas) e os extratos em hexano, em diclorometano e em etanol de folhas e ramos de Tr

18. Tratamento de sementes, densidade e método de semeadura de Brachiaria brizantha no consórcio milho e braquiária / Treatment of seed, density and sowing methods of Brachiaria brizantha intercropping maize and pasture
The integrated crop livestock farming system is an important training and renovation of degraded pastures. However, lack technical information about physiological and sanitary quality of the forage seeds and sowing methods have been suggested as causes of failure in some fields. This work aimed to evaluate the effects of treatment of seeds of Brachiaria briz

19. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

20. Acute toxicological effects of extracts of Melia azedarach (Meliaceae) in rats (Rattus norvegicus), mice (Mus musculus) and Artemia salina / Efeitos toxicológicos agudos de extratos de Melia azedarach (MELIACEAE) em ratos (Rattus novergicus), camundongos (Mus musculus) e Artemia salina
The revival of research involving botanical insecticides owes itself to the need to make available new products devoid of environmental degradation, with lesser residual affects and development of resistant insects to synthetic products. Phytochemicals from the family Meliaceae have been considered preeminent pesticides. Among the Maliaceae, one of the plant

The family Brassicaceae is one of the most economically important in the world, having as their main pest to Plutella xylostella (L.) (Lepidoptera: Plutellidae), which causes great damage to the crop with up to 100% of yield losses. In order to investigate alternatives to synthetic insecticides, medicinal plants have been in recent years in search of compoun
