This study was carried out to determine the plant protection practices of the garlic growers in Gaziantep province. For this purpose, a survey consisting of 20 questions and based on simple random sampling method was conducted with 81 growers in each of the districts of Araban, Oguzeli, Yavuzeli, Central, Nurdagı, Nizip and Karkamış districts in 2018. The data evaluated and expressed as percent ratio. According to the findings from the surveys, garlic growers stated that they preferred pesticide dealers suggestions for the selection and determination of doses of pesticides used in pests and diseases, they also stated that the price and expiration date were not an important factor in the selection of pesticides. In addition, it is found that growers avoid using the same pesticide continuously against same diseases and pests, they do not make any changes in there commended pesticide doses, pesticides leave residues on the products, they paid attention the time between the last application and harvest. It has been reported that the use of protective clothing and mask during the application by the growers is relative, they do not use pesticides as a mixture, they apply different processes to empty pesticide boxes. It was determined that garlic growers prefered chemical control and did not have knowledge about the concept of biopesticides.

Promoting the agricultural sector with up-to-date technologies and inputs is convenient to enhance productivity. Production intervention is needed by introducing and adopting proper agronomic practices. Improved agricultural technologies increase production, quality, sustain food security, economic development and natural resource conservation. Koka, Meki and Ziway are known for their vegetable production as well as intensive agrochemicals consumption. Agrochemicals are applied on farm to enhance soil fertility, reduce pathogens, and induce plant growth. Tomato is one of the main commercial cash crops in these areas. Most commercially productive tomato varieties are highly sensitive to disease, vulnerable to nutrient deficiency, and other abiotic stress that requires rigorous agrochemical inputs. Ethiopian tomato production is very low due to various contributing factors including lack of improved varieties, diseases, pests, poor farming system, soil fertility maintenance as well as poor irrigation system. Farmers in the study areas applied inaccurate agrochemicals dose, rate, and application schedule that foster repeated spray. Intense agrochemical application leads to adverse environmental and health impacts due to deposit of toxic chemicals, residue leakage to water bodies and air pollution. It is important to practice proper agricultural inputs, reduce hazardous chemical residues, protect humans, other beneficial organisms and the environment. Moreover, developing IPM technology is recommended for better healthy agricultural production and sustainability.

The present study was conducted to investigate the effectiveness of lycopene in alleviating the toxicity of cypermethrin (CYP) on haematological parameters in carp, Cyprinus carpio. Fish (totally 140 fish) were exposed to sublethal concentrations (0.202 and 0.404 μg/L) of CYP, and lycopene (10 mg per kg of fish weight) was simultaneously administered. At the end of 28 days administration, blood samples were collected and haematological changes (red and white blood cell count, haemoglobin concentration, haematocrit level, and erythrocyte indices: mean corpuscular volume, mean corpuscular haemoglobin, and mean corpuscular haemoglobin concentration) were determined. According to the data obtained, CYP was determined to lead to negative alterations in the haematological parameters investigated. The administration of lycopene alleviated this effect.
