In agricultural pest management, botanical pesticides are most suitable for use in organic food (agricultural) production due to their safety to humans and the environment compared to conventional pesticides. Compounds of plant origin can be highly effective, with diverse and multiple mechanisms of action, and with low toxicity towards non-target organisms.

The objective of the study "Effects of some commercial products on root and crown rot caused by Phytophthora cactorum in apple cultivation" was to evaluate the effects of eleven commercial products (bio-pesticides, fertilizers, and activators) on P. cactorum by comparing plant growth parameters (trunk diameter, plant height, number of branches, and root dry weight). Trials were conducted according to a randomized complete block design with three replicates in a greenhouse in 2 consecutive years.

The results indicated that the vegetation set achieved 90% of Imidacloprid removal efficiency while the control set (only soil media) removed Imidacloprid at a range between 64.9 to 65.9%. Furthermore, the vegetation set with additives also resulted in the increment of Dissolved Oxygen (DO) with about 16% and pH increment between 2 to 11% for all treatment train sets with a better water quality improvement.

The organophosphate target enzyme paraoxonase-1 (PON1) has been extensively studied in toxicology. Pesticides are organophosphate compounds that are commonly used in agriculture. They are also used as nerve gases, such as sarin and soman. Therefore, the effects of these compounds on enzymatic activity are well known. In the present study, we investigated the in vitro effects of fenoxaprop-p-ethyl, lambda cyhalothrin, imidacloprid, and dichlorvos pesticides on sheep liver microsomal PON1.

Organic agricultural production has been taking place in many countries around the world with a strong shift from traditional agriculture to sustainable agriculture in order to create high-value agricultural products with food safety, environmental protection and climate change adaptation. Organic agricultural production is considered as the natural farming with strict control of irrigation water, unpolluted soil and no use of chemical fertilizers, pesticides, herbicides, growth stimulants and plant varieties, livestock and materials derived from genetically modified organisms.

Tomato leaf miner is an aggressive and invasive pest that causes serious damage in tomato production, resulting in up to 100% yield losses during serious outbreaks. The management of tomato leaf miner with synthetic pesticides is difficult due to its leaf mining habit, short life span, high reproductive rates, and insecticide resistance problem. In this study, sequences of the mitochondrial cytochrome oxidase I (mtCOI) gene of Tuta absoluta specimens were analyzed and compared with the available COI sequence data members from GenBank.

This study was conducted to determine the effects of different position angles in twin-jet spray applications on droplet penetration of different nozzle types. Seven different nozzle types (standard flat fan, ST; narrow flat fan, STN; multirange, LU; lowdrift potential, AD; air-induction, IDK; twin-jet air-induction, IDKT) were used and nozzles were positioned +15° along the forward direction, perpendicular to ground surface 0˚ and reverse direction of forward –15°. Spray experiments at 100 L/ha constant application volume were conducted under controlled conditions of a closed facility.

Open-field farming involves successive major processes such as preparation of soil, planting the seed, adding pesticides and fertilizers, irrigation, cultivation, and harvest. The main aim of all processes is to achieve maximum yield out of the available agricultural landscape. It is necessary to collect geo-referenced descriptive data on soil characteristics, such as soil penetration resistance and electrical conductivity before starting all these processes.

Agricultural insects are one of the major threats to crop yield. It is a known fact that pesticide application is an extensive approach to eliminate insect pests, and has severe adverse effects on environment and ecosystem; however, there is lack of knowledge whether it could influence the physiology and metabolic processes in plants.
