Abstract:
... Cultural control methods in integrated pest management (IPM) refer to practices that modify the agricultural environment in ways that favour crop protection to the detriment of pest performance. Trap cropping is one of these practices and involves luring insect pests away from the main crop to a more attractive host plant growing beside or around the crop. The trap crop can then be destroyed, and ...

Abstract:
... Chilli fruits with symptoms of anthracnose were collected from Batangas, Philippines, to determine the etiology of the disease. The fungus was initially identified as Colletotrichum acutatum sensu lato based on its morpho-cultural characteristics and molecular identity by using primer sets CaInt2/ITS4. Further analyses of three important gene regions, namely internal transcribed spacer (ITS), part ...

Abstract:
... Bacterial blight (BB), caused by Xanthomonas oryzae pv. Oryzae (Xoo), is one of the most serious diseases of rice causing a significant yield loss mostly in Asia and parts of Africa and poses a threat to the breakdown of varietal resistance. Development of resistant varieties carrying major resistance (R) gene(s) has been the effective way for controlling BB. The type of R gene(s) to be deployed d ...

Antiviral activity of the extract was retained for a period of 9 days on treated faba bean leaves. This activity was considerably decreased at concentrations lower than 30 mg mL−1, and by washing the treated leaves of ...

Abstract:
... Prairie voles (Microtus ochrogaster Wagner) cause extensive damage in agricultural, suburban, and urban environments. Control of these animals has historically relied on the use of anticoagulant rodenticides and zinc phosphide. However, shyness to zinc phosphide baits has reduced its efficacy. The aim of this study was to evaluate the factors involved in zinc phosphide bait shyness through prefere ...

Abstract:
... Ralstonia spp., the causal agents of bacterial wilt, cause severe yield losses of Solanaceous crops, including tomato. The disease is difficult to control due to the pathogen's ability to survive in soil and to cause latent infections. Therefore, characterizing Ralstonia strains is important in developing effective strategies for diagnoses, quarantine and selection of biocontrol agents. In this st ...
