Grain surface-layer treatment of diatomaceous earth for insect control.
This paper describes an alternative method to synthetic insecticides used for protection of stored agricultural products the purpose of which is to minimise the everyday human exposure to those chemicals. The method uses diatomaceous earth which is practically non-toxic to humans and fully acceptable for the environment. Fifty and 100-cm-deep layers of Hard Red Spring wheat Triticum aestivum (L...
متن کاملDiatomaceous Earth for Pest Control
Least toxic physical and chemical solutions are often part of an IPM program. Various forms of amorphous silica are commonly used as part of this strategy. Diatomaceous earth and silica gel are used in various physical formulations with or without added pesticide. The type of silica and the formulation depend on the target pest. In this issue advantages and disadvantages of diatomaceous earth a...
متن کاملEvaluation of methoprene alone and in combination with diatomaceous earth to control Rhyzopertha dominica (Coleoptera: Bostrichidae) on stored wheat
A series of experiments were conducted in which different formulations of the insect growth regulator methoprene were evaluated for control of Rhyzopertha dominica (F.), the lesser grain borer, a major internal insect pest of stored wheat. In the first test, application rates of 10-ppm R;S-methoprene (a racemic mixture of the R and S isomers of methoprene) and 1 and 5-ppm S-methoprene (S-isomer...
متن کاملControl of Rhyzopertha dominica in stored rough rice through a combination of diatomaceous earth and varietal resistance
Adults of Rhyzopertha dominica (F.), the lesser grain borer, were exposed on four varieties of rough rice with Dobie indices of susceptibility of 1.1 to 1.1 (low), and four varieties with Dobie indices of susceptibility of 3.4 to 3.8 (high). The varieties with low and high Dobie indices were classified as resistant and susceptible, respectively, to R. dominica. The purpose of the study was to e...
متن کاملInsecticidal effect of spinosad dust, in combination with diatomaceous earth, against two stored-grain beetle species
flour beetles, Tribolium confusum. Efficacy was assessed on wheat and maize at three dosages of spinosad dust formulation (corresponding to 0.0625, 0.1875 and 0.625ppm of active ingredient [AI] for S. oryzae and to 0.1875, 0.625 and 1.25 ppm of AI for T. confusum), alone or combined with SilicoSec at 150ppm for S. oryzae and 250 ppm for T. confusum. The mortality of S. oryzae exposed for 14d on...
