    The efficacy of karate (lambdacyhalothrin) in controlling heloidogyne incognita (kofoid and white) on soybeans (glycine max. L. Merril.)
    (1997) Fadina, O.O; Adesiyan, S.O.
    The nematicidal properties of a synthetic pyrethriod (Karate) was investigated. In laboratory experiments, Karate at different concentrations (4,000ppm, 6,000ppm and 8,000pm against Meloidogyne incognita (kofoid and white) prevented egg- hatch and accentuated the death of the infective second stage juveniles. In green-house experiments, as little as 4,000ppm of Karate reduced both the number of galls and the population of juveniles in soils when compare with the Control plants. However, Karate applied as soil-drench resulted in wilting of plants at all concentrations

    The Effects of Single and Combined Repetitive Oral Administration of Common Pesticides and Alcohol on Rabbits
    (1999) Fadina, O.O; Taiwo, V.O; Ogunsunmi, A.O
    The toxicological effects of repetitive single or combined oral administration of a synthetic pyrethroid pesticide (KarateR), nicotine and alcohol (ethanol) in rabbits were studied. Rabbits given daily oral doses of either KarateR, nicotine or ethanol and a combination of either KarateR and nicotine or alcohol exhibited various forms and severities of nervous signs, haematological and serum biochemical alterations, and lungs, liver, heart, kidney and brain damage. Single repetitive nicotine consumption proved most fatal with 75% mortality rate recorded within eight weeks, while combined KarateR and alcohol consumption caused 100% mortality within ten weeks. Severe anaemia, panleucopenia, significant increase in serum gammaglutamyl transferase and hypocholesterolaemia were the hallmarks of severe toxicity with these agents. This study highlights the possible long-term effects of the indiscriminate use of pesticides, and some common environmental pollutants like alcohol on rabbits. This very serious threat to biodiversity Conservation efforts in our environment that may result from this is discussed.
