Different types of pests are found in nature affecting life and yield of natural and cultivated crops of agro-forestry. Researchers are trying to develop and apply different techniques to control and reduce loss of these pests on agriculture, forest and garden products. Chemical control method (CCM) is frequently applied as it is easy and prompt way to directly kill or repel the pests from crop...

Herbicides are widely used as an important alternative to prevent excessive growth of weeds in agricultural crop land, particularly where conservation tillage is adopted. Weeds reduce crop yield and quality, interfere with cultivation and harvest operations and seem to be the most economically important of all pests with respect to sales of pesticides worldwide. As an interesting side effect, t...

The detection of weeds at the stages cultivation is very important for detecting and preventing plant diseases eliminating significant crop losses, traditional methods performing this process require large costs human resources, in addition to exposing workers risk contamination with harmful chemicals. To solve above tasks, also order save herbicides pesticides, obtain environmentally friendly ...

Breeding innovations are relevant for sustainable agricultural development and food security, as new, resilient production systems require crop varieties optimally suited these systems. In the societal debate around genetic engineering other plant breeding innovations, ownership of patents on technology used in hands large companies is often seen a reason that small denied opportunities further...

1 Part 340 regulates, among other things, the introduction of organisms and products altered or produced through genetic engineering that are plant pests or are believed to be plant pests. The introduction into the United States of such articles also may be subject to other regulations promulgated under the Plant Protection Act (7 U.S.C. 7701–7772) and found in 7 CFR parts 319, 330, and 360. Fo...

Many studies of plant competition have been directed towards understanding how plants respond to density in monocultures and how the presence of weeds affects yield in crops. In this Botanical Briefing, the development and current understanding of plant competition is reviewed, with particular emphasis being placed on the theory of plant competition and the development and application of mathem...

Weeds were collected from a ginger fi eld experiencing a bacterial wilt outbreak. These weeds were assayed for the presence of the pathogen (Ralstonia solanacearum) using a PCR assay. The pathogen was detected from the rhizosphere soil of many but not all samples. We hypothesize that weeds that consistently harbor high populations of this bacterium may serve as an alternate host, and indicator ...

Bacteria and fungi that colonise plant surfaces and internal plant tissues (epiphytes and endophytes respectively) are ubiquitous, residing latently or actively colonising the plant locally as well as systemically. Endophytic microorganisms generally originate from the epiphytic communities of the root or aerial surfaces as well as from within seed material. Besides entering plants through natu...

In modern agriculture, climate change, environmental degradation, and natural resource depletion constitute one of the major potential issues for sustainable crop production management. Integrated pest management (IPM) is a promising technology environment. Insect pests weeds have long posed danger to rice systems, resulting in severe output losses. Although insect, pest, weed control has remai...
