Three greenhouse experiments were conducted to evaluate western corn rootworm, Diabrotica virgifera virgifera LeConte, beetle emergence from individual pots containing glyphosate-tolerant transgenic corn, Zea mays L., expressing the Cry3Bbl endotoxin from the soil bacterium Bacillus thuringiensis Berliner (MON863), nontransgenic glyphosate-tolerant isoline corn, grassy weeds (giant foxtail, Set...

The use of chemical pesticides to protect agricultural products is a global concern because their adverse effects on the environment and public health. To avoid dangers synthetic herbicides, research has turned natural alternatives. This study was conducted evaluate allelopathic effect essential oil (EO) extracted from Origanum syriacum, onites, majorana. In addition, composition elucidated by ...

Weeds are a serious problem of chickpea cultivation in rain-fed areas of Iran and economic feasibility of crop production is mostly challenged by the method of control. In this study, two types of weed control strategies which are common in the country, including hand removing and hand removing + mechanical application, were compared with application of general herbicide (Glyphosite) using a sp...

The agrochemical spreading is a common and essential agricoltural practice to obtain high quality, large harvests. Agrochemicals are classified according to the target organisms designed to be controlled (insects, weeds, fungi). Of all the target organisms, weeds cause by far the greatest economic loss due to their interference in crop production. It is not surprising therefore, that herbicides...

Honey bees (Apis mellifera L.) are the main pollinating agents for numerous plants and fruit trees and hence, play a key role in agriculture and more generally in the maintenance of ecological biodiversity. They are mostly affected farm animals by pesticides. Indeed, pesticides work in two ways to reduce bee populations. First, many pesticides used in crop production are highly toxic to these s...

Invasive weeds are a serious problem worldwide, threatening biodiversity and damaging economies. Modeling potential distributions of invasive weeds can prioritize locations for monitoring and control efforts, increasing management efficiency. Forecasts of invasion risk at regional to continental scales are enabled by readily available downscaled climate surfaces together with an increasing numb...

Worldwide pesticides are used by farmers for growing more food on less land protecting crops from pests, diseases and weeds as well raising productivity per hectare. Also, enable to produce safe, quality foods at affordable prices. Therefore, the market agricultural is anticipated rise $ 26.23 billion between 2021 2025. Pesticide residues can be discovered in a wide range of common drinks, such...
