The most prevalent insect pests found infesting soybean at the vegetative and early flowering stages, 2 weeks after planting (WAP) to 8 WAP in all the intercropping patterns were the defoliators, Monolepta duplicata Sahl. and Ootheca mutabilis Linnaeus. The stink bugs, Nezara viridula Linnaeus and Aspavia armigera Fabricuis attacked soybean plants from 8 WAP to 14 WAP, at the reproductive stage up to the pod drying stage. During both years, the peak populations for the defoliators and stink bugs ranged from 4 WAP to 5 WAP and 10 WAP to 11 WAP, respectively. Soybean planted sole had more leaf damage and significantly (P = 0.05) higher incidence of M duplicata, O. mutabilis, N. viridula and A. armigera than in other cropping patterns, with soybean planted on the crest of the ...

Many factors have influenced these practices including socio-economic variables which either encourage or discourage the pesticides use. This investigation involved a survey of eighty (80) arable crop farmers’ selected using multi-stage random sampling technique in Njaba local Government Area of Imo State of Nigeria. Result reveals that farm size, farming experience, number of times in contact with extension agents in a month, level of educational attainment, and cost of pesticides were factors that influenced use and adherence to recommended dosage of pesticides by farmers. Pesticides when properly applied in the right dosage, under dry weather condition gave good results especially in the short run. Extension outfit should encourage the farmers to...

The major insect pests found infesting soybean at 26 to 56 days after planting (DAP) in all the insecticidal treatments were the defoliators, Monolepta duplicata Sahl and Ootheca mutabilis Sahl while the stink bugs, Nezara viridula Linnaeus and Aspavia armigera Fabricius attacked soybean from 56DAP to 86DAP, respectively. During both years, it was found that the insecticides significantly (P Mantis religiosa L. (Mantidae). It was also found that the insecticides significantly (P Int. J. Agric.

The incidence of the defoliators, Monolepta duplicata Sahl and Ootheca mutabilis Linnaeus in all the planting dates were earlier (2 weeks after planting, 2WAP) up to 8WAP. However, the stink bugs, Nezara viridula Linnaeus and Aspavia armigera Fabricius were found infesting soybean pods from 8WAP to 14 WAP. The peak populations of the defoliators and stinkbugs were recorded at 4WAP and 10WAP, respectively. The crop planted on August 20 had a significantly (P [IJARD Vol.3 2002: 121-126]

This could be seen in the involvement of both Federal and State governments in the formulation and implementation of agricultural development policies and programmes with extension components. This was to increase the productivity and level of income of the farmers, but not many farmers benefited from these programmes as the programmes were not properly planned and executed (Ali, 1989). The goal of agricultural extension is to disseminate agricultural technologies for improving productivity, farmers’ welfare and household nutritional status (Fabiyi, 2015).
