Abstract:

Tomato fruit (Lycopersicon esculentum Mill) is an important vegetable commodity in Ghana, as it is consumed daily in many households either heat-treated or without any form of heat treatments. Tomato production is a major source of income for many smallholder producers in Northern Ghana especially through dry season farming when the major supply of tomatoes from Southern Ghana is exhausted. Research conducted for the past decade confirmed the presence of pesticide residues in fruits and vegetables such as cabbage, onion, cucumber, lettuce, tomatoes, okra and pepper.

AbstractInsect-pollinated plants are essential for honey bees to feed their brood. In agricultural landscapes, honey bees and other pollinators are often exposed to pesticides used for cultivation. In order to gain more insight into the fluctuation of pesticide loads, 102 daily pollen samples were collected between April and July 2018 in a fruit-growing area in Southern Germany. Samples were analyzed with respect to more than 260 pesticides using a multi-residue pesticide analysis method. Almost 90% of the analyzed pollen samples featured between one and thirteen different pesticides. In total

This review considers potential approaches to solve an important problem concerning the impact of applied pesticides of various classes on living organisms, mainly agricultural crops used as food. We used the method of multi-residual determination of several pesticides in agricultural food products with its practical application for estimating pesticides in real products and in model experiments. The distribution of the pesticide between the components of the soil-plant system was studied with a pesticide of the sulfonylureas class, i.e., rimsulfuron.

Leafy vegetables are widely consumed in South Korea, especially in the form of kimchi and namul (seasoned vegetables) and are used for wrapping meat. Therefore, the management of pesticide residues in leafy vegetables is very important. A total of 17,977 samples (49 leafy vegetables) were mainly collected in the largest production area of leafy vegetables (Gwangju Metropolitan City and Chonnam Province) in South Korea. They were analyzed within the government’s monitoring programs (Gwangju Metropolitan City) of pesticide residues between 2005 and 2019. Pesticide residues were found in 2815 sam

Abstract:

Soil is normally the final destination of pesticides applied to cultures. After a series of applications, various pesticides reach the soil due to direct application or leaf washing. However, some amount of the pesticides, particularly foliar pesticides, are intercepted and absorbed by the leaves of the weeds or by the culture itself. Plants contaminated with pesticides may return to the soil during the culture cycle (leaf senescence) or after harvesting (as crop residues). The destination of the pesticide residues in the soil from plant material is both generally ignored and unknown. The pest

The results reflected slight contamination of some of the water samples with residues of diazinon, chlorpyriphos (organophosphorus insecticide), carbaryl and carbofuran (carbamate insecticide). The concentration of diazinon and chlorpyriphos ranged from 2.31 jig/L to 5.60 pg/L and 0.0 to 3.80 pg/L respectively. Among carbamate pesticides, carbofuran identified in two samples, ranging from 1.40 to 3.71pg/L, carbaryl was detected

Rice (Oryza sativa L.) is the staple food of more than half of the world’s population. The main factors affecting the quality of rice include grain length, texture, stickiness, flavor, and aroma. Pesticides are intended for the protection of plant products from weeds, fungi, or insects. However, pesticides also result in negative effects such as environment disturbances, pest resistance and toxicity to both users and food consumers.

Among these, the incidence of pesticide resistance is a growing problem in stored product protection. Problems associated with synthetic pesticides, especially pesticide resistance, have created a worldwide interest in the development of alternative biorational strategies.
