Article Synopsis
  • The study investigated the effectiveness of leaf powders from the Asteraceae (Al) and Malvaceae (Ad) families against the Haemonchus contortus nematode in sheep.
  • Twenty-eight sheep were infected and divided into four groups, with two receiving the leaf powders, one receiving a standard drug (albendazole), and the last receiving water.
  • Results indicated significant reductions in egg production and improvements in health parameters for sheep treated with Al and Ad, suggesting these leaf powders could serve as alternative treatments for controlling haemonchosis in small ruminants.

The role that owner-managers' managerial capabilities play in agricultural firms' strategic change and performance is still unclear. A firm's market opportunities seizing capability (OSC) is a source of competitiveness and superior performance. The objective of this study is to establish how owner-manager's dynamic managerial capabilities (DMCs) including managerial human capital, managerial social capital and managerial cognition affect firm performance through the mediating effect of OSC, as well as the moderating effect of market dynamism in the relationship OSC and firm performance.

The Asian citrus psyllid (ACP), Diaphorina citri, was detected for the first time in the Republic of Benin, West Africa. The ACP is a known vector of Candidatus Liberibacter asiaticus (CLas), the putative causal agent of the devastating Huanglongbing (HLB; citrus greening disease). During visual surveys, ACP was only observed on residential citrus trees in southern Benin, but not in residential areas or commercial groves in the central and northern parts of the country.

is an indigenous species in Africa and has been reported in the destruction of several crops in Benin. Management of pest is mainly focused on the use of synthetic pyrethroids, which may contribute to resistance selection. This study aimed to screen the susceptibility pattern of field populations of to deltamethrin in Benin.

Background: Several studies have reported the strong resistance of complex species to pyrethroids. The voltage-dependent sodium channel () gene is the main target of pyrethroids and DDT. In Benin, the frequency of the resistant allele () of this gene varies along the north-south transect.

In this study, the adequacy of the late blight simulation model LATEBLIGHT (version LB2004) was evaluated under Nicaraguan conditions. During 2007 to 2008, five field experiments were conducted in three potato-production regions in northern Nicaragua. Two susceptible ('Cal White' and 'Granola') and one resistant ('Jacqueline Lee') potato cultivars were evaluated without use of fungicides and with three application intervals (4, 7, and 14 days) of the fungicide chlorothalonil.
