Evaporation time of droplets containing thiamethoxam and adjuvants on hydrophil...
Lasmar, Olinto; Rodrigues da Cunha, João Paulo ArantesThe efficacy of pesticide applications is related to the spread and evaporation time of the droplets deposited on the target. This study evaluates the evaporation of spray droplets containing thiamethoxam and adjuvants on different surfaces and at different levels of relative air humidity. A climate controlled chamber was set up with a digital microscope to produce images of droplet evaporation. Three surfaces ...
Efficiency of reduced volume spraying aimed to control the Leucoptera coffeella...
Lasmar, Olinto; Ferreira, Marcelo da Costa; Decaro Junior, Sergio Tadeu; Fouquet, GuntherThe objective of the study was to evaluate the application efficiency with reduced volume from the prototype of a pneumatic spray nozzles aimed to control the coffee leaf miner (Leucoptera coffeella). We evaluated different types of pneumatic nozzles (flat fan, cone jet, AT-1000 model and effervescent), on application of insecticide spray liquids with concentrations of 5, 10, 15 and 20% (v/v) of mineral oil app...
Reducing spray volume for the control of Leucoptera coffeella (Lepidoptera: Lyo...
Decaro Junior, Sergio Tadeu; Ferreira, Marcelo da Costa; Lasmar, Olinto; Fouquet, GuntherThe present work evaluated reducing on spray volume for the control of Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842; Lepidoptera: Lyonetiidae) in coffee. Were used a conventional sprayer to apply the volumes 400 and 200 L ha-1 and an ultra-low-volume (ULV) sprayer to apply 46, 67 and 92 L ha-1. Sprays utilized 800 mL.ha-1 of the insecticide profenofos+lufenuron. The tracer MnSO4 was mixed to the...
Insecticidal activity of extracts of plants in the contrl of leaf cutting ant i...
Torres, Andrea de Fátima; Lasmar, Olinto; Carvalho, Geraldo Andrade; Santa-Cecília, Lenira Viana Costa; Zanetti, Ronald; de Oliveira, DenilsonThe objective of this work was to evaluate the efficiency of extracts of plants from Minas Gerais in the control of leaf cutting ant Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae). Seventy plant extracts were evaluated, being applied to the diet of the test insects. It was verified that only the botanical extracts Eugenia florida and Eugenia handroana (Myrtaceae), Trichilia pallida (Meliaceae) and Zan...

Ferreira, Marcelo da Costa; Lasmar, Olinto; Decaro Junior, Sergio Tadeu; Neves, Samira Scaff; de Azevedo, Letícia HenriqueO trabalho objetivou avaliar os perfis de distribuição volumétrica, o diâmetro de gotas, a tensão superficial, o ângulo de contato de gotas e a deposição de calda de pulverização sobre folhas de amendoim (Arachis hypogaea L.) submetidas à chuva artificial, em comparação à deposição sem chuva, usando-se dois modelos de pontas hidráulicas de jatos planos e caldas inseticidas com e sem adição de adjuvantes. Utiliz...
Cobertura e depósito de calda fitossanitária em plantas de café pulverizadas co...
Ferreira, Marcelo da Costa; Leite, Gilson José; Lasmar, OlintoO objetivo deste trabalho foi avaliar a cobertura de gotas de pulverização sobre plantas de café bem como o seu depósito utilizando um pulverizador com e sem adaptação de um ramal auxiliar para plantas altas. O experimento foi realizado em outubro de 2011, no município de Patrocínio-MG, sendo as parcelas experimentais constituídas de 30 plantas da variedade Catuaí IAC-99, com aproximadamente 12 anos de idade e ...
Residual effect of synthetic insecticides on Trichogramma pretiosum Riley (Hym....
Moscardini, Valéria Fonseca; Moura, Alexandre Pinho de; Carvalho, Geraldo Andrade; Lasmar, OlintoThis work aimed to evaluate the residual effects of the pesticides etofenprox, fenitrothion, methidathion and trichlorfon on adults of Trichogramma pretiosum, as well as on F1 and F2 generations of this parasitoid species, under laboratory conditions. Eggs of the factitious host Anagasta kuehniella (Zeller) (Lep., Pyralidae) were glued to blue paper cards, UV-killed and treated by dipping in the aqueous solutio...
