In spite of advances in invertebrate pest management, the agricultural industry is suffering from impeded pest control exacerbated by global climate changes that have altered rain patterns to favour opportunistic breeding. Thus, novel naturally derived chemical compounds toxic to both terrestrial and aquatic invertebrates are of interest, as potential pesticides. In this regard, marine cyanobac...
Advances in Targeted Pesticides with Environmentally Responsive Controlled Release by Nanotechnology
Pesticides are the basis for defending against major biological disasters and important for ensuring national food security. Biocompatible, biodegradable, intelligent, and responsive materials are currently an emerging area of interest in the field of efficient, safe, and green pesticide formulation. Using nanotechnology to design and prepare targeted pesticides with environmentally responsive ...
Synthetic pesticides are fairly well recognized as a cost-effective method of controlling pests, but these chemicals are toxic to other non-targeted and beneficial species. Pesticides are either directly applied to soil to control soil borne pests or deposited on soil as runoff from their foliar applications and these concentrations are highly enough to effect soil micro-organisms (Bezchlebova ...
The pesticides industry needs to look differently from the existing basis that toxic materials are required in order to eliminate pests and weeds from food crops. New generation of pesticides will be motivated by a knowledge of metabolic pathways. The article reviews the effectiveness of several classes of natural pest control agents such as: pheromones, allelopathic chemicals, toxicants from t...
The urbanization of agriculture sector leads to an increased chemical affliction on the environment. Pesticides are chemicals used in protect plants from weeds, pests or diseases and human being various diseases. In this review, literature different types pesticides, pesticide usage its toxic effects mammalian systems summarized. Most commonly pesticides fungicides, insecticides herbicides cont...
Rationale The use of biological control organisms to augment chemical pesticide applications is gaining popularity amongst the environmentally conscious. While a moderate amount of information is known about the effect of pesticides on the indigenous ecology of a given environment, relatively little data exists describing the effect of introducing living organisms to a native community, especia...
Climate change induced by anthropogenic warming of the earth's atmosphere is a daunting problem. This review examines one of the consequences of climate change that has only recently attracted attention: namely, the effects of climate change on the environmental distribution and toxicity of chemical pollutants. A review was undertaken of the scientific literature (original research articles, re...
When it comes to pesticides’ effects on frogs, sublethal concentrations do not preclude lethality. That’s the conclusion of a new study published in the October issue of the journal Ecological Applications. After dosing wood frogs and leopard frogs with very small concentrations of the popular pesticide malathion, the researchers discovered that the chemical did not kill the frogs directly—inst...
The aim of present study was to assess pesticide residues in vegetables in the Pathanamthittadistrict.The concentrations of six pesticides were determined by gas chromatography coupled with mass selective detector (GC-MS) in locally produced vegetables purchased from wholesale markets. A total of 20 samples of four vegetables viz. Pea, snakegaurd, bittergaurd,brinjalwereanalyzed for pesticide r...
