“…This is similar to Ayuba et al (2012) and Ayuba and Ofojekwu (2002) who worked on Datura innoxia root extracts. Generally toxicity increased with reduced oxygen concentration as reported by Adigun (2003) and Kolo et al (2008;.…”

The acute toxicity of aqueous Datura innoxia leaf extract on Clarias gariepinus juveniles was accessed, five concentration of the extract where used during the definitive preliminary test as follows 125mg/l, 167mg/l 208mg/l 250mg/l and 292mg/l for a period of 96 hours on Clarias gariepinus juveniles of mean weight 31.07 ± 1.23g and mean length of 19.50 ± 0.5cm and stocked 10 fishes per treatment. Acute toxicity was carried out for 96 hours to determine LC50 . The 96 hours LC50 for Datura innoxia leaf extract was 176mg/l with regression coefficient of R2 is 0.967. The pooled blood samples were collected at the end of the 96 hours of exposure to aqueous Datura innoxia leaf extract and were examined using digital analyser. Haematological variables showed significant decreases (P˂0.05) of blood variables such as HCT, HB, RBC, MCHC and significant increase in values of WBC, PLT, MCH, and MCV during acute toxicity of Datura innoxia leaf extract.

Potato is one of the most important crops, after maize, rice and wheat. Its global production is about 300 million tons per year and is constantly increasing. It grows in temperate climate and is used as a source of starch, food, and in breeding industry.Potato cultivation requires application of numerous agro-technical products, including pesticides, since it can be affected by insects, weeds, fungi, and viruses. In the European Union the most frequently used pesticides in potato cultivations check are: thiamethoxam, lambda-cyhalothrin and deltamethrin (insecticides), rimsulfuron (herbicide) and metalaxyl (fungicide).Application of pesticides improves crop efficiency, however, as pesticides are not totally selective, it affects also non-target organisms. Moreover, the agrochemicals may accumulate in crops and, as a consequence, negatively influence the quality of food products and consumer health. Additional risks of plant protection products are related to their derivatives, that are created both in the environment (soil, water) and in plant organisms, since many of these compounds may exhibit toxic effects.This article is devoted to the degradation processes of pesticides used in potato crop protection. Attention is also paid to the toxicity of both parent compounds and their degradation products for living organisms, including humans. Information about the level of pesticide contamination in the environment (water, soil) and accumulation level in edible plants complement the current knowledge about the risks associated with widespread use of thiamethoxam, lambda-cyhalothrin and deltamethrin, rimsulfuron and metalaxyl in potato cultivation.
