Antifungal and toxicity effects of new combined essential oils on Oncorhynchus mykiss in comparison with malachite green [PDF]

The Iranian Journal of Veterinary Science and Technology, 2012
Mold infection is one of the most important problems in aquaculture. Recently, administration of some chemicals such as malachite green in order to control mold infections has been limited in aquaculture. In the current decade, researchers have been more

Nematicidal activity of plant extracts against the root-knot nematode, Meloidogyne incognita [PDF]

, 2009
Nematicidal activity of extracts from plants was assayed against Meloidogyne incognita. In laboratory assays extracts from tobacco (Nicotiana tabacum L), clove (Syzygium aromaticum L), betelvine (Piper betle L), and sweet flag (Acorus calamus L) were ...

Drivers of copper sensitivity in copepods: A meta-analysis of LC50s

Ecotoxicology and Environmental Safety, 2022
Copper is both an essential trace element and a potent pesticide. The use of copper as an antifoulant has increased in the last decades in line with the expanding aquaculture and shipping industries. In aquatic environments, it also affects non-target taxa. One of which are copepods, which constitute the central link in the marine food web.

A mathematical model for estimating the LC50 (or LD50) among an insect life cycle

Egyptian Academic Journal of Biological Sciences. A, Entomology, 2010
In this study, a mathematical model is made to estimate the median lethal concentration or dose (LC50 or LD50). The model is based on the data of different insecticide groups, where each one is represented by the effect of three insecticides over ...

Tailored Organogel Systems for Optimized Pesticide Delivery: Mechanistic Insights and Agricultural Applications

Advanced Science, EarlyView.
Utilizing molecular engineering for network design, three pesticide‐loaded organogels (PLOs) carriers exhibiting varying degrees of flexibility were prepared. The mechanical properties of these carriers, tunable via their network molecular structures, enhance their structural adaptability and retention stability at biological interfaces, thereby ...

Evaluation of acute toxicity of copper cyanide to freshwater fish, Catla catla (Hamilton) [PDF]

Journal of Central European Agriculture, 2011
The acute toxicity of copper cyanide to the juveniles of Indian major carp Catla catla (2±0.5 cm) was evaluated under static renewal conditions. The concentrations of copper cyanide that killed 50% of the carp fingerlings within 96-h (96-h LC50) was ...

Acaricidal activity of small molecule antagonists of the tick kinin receptor against Rhipicephalus microplus acaricide-susceptible and resistant strains. [PDF]

Pest Manag Sci
Two small molecules, SACC‐0039590 and SACC‐0428788, killed cattle fever tick, R. microplus, susceptible Deutch strain and pyrethroid resistant Arauquita strain larvae. SACC‐0039590 at 1 mM decreased the reproductive parameters of Deutch females. Abstract BACKGROUND Resistance to acaricides underscores the need for tick control alternatives.
