Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...
However, disease control is reasonably successful for most crops. Disease control is achieved by use of plants that have been bred for good resistance to many diseases, and by plant cultivation approaches such as crop rotation, pathogen-free seed, appropriate planting date and plant density, control of field moisture, and pesticide use.
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
To date, work on induction of plant systemic resistance has shown that inducing plant system resistance work has important implications for basic and applied research. Induced resistance applications in melons, tobacco, bean, potato, and rice have achieved significant success. Over the past decade, the study of induced system resistance has ...
Take care not to use too much fertilizer, though, as overfertilizing can cause plants to produce new, tender growth, which attracts thrips. Related: The 10 Best Fertilizers for Indoor Plants of ...
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
Upon entry of a pathogen, plants are vulnerable to infection and lose a fair amount of nutrients to said pathogen. The constitutive defenses are the physical barriers of the plant; including the cuticle or even the metabolites that act toxic and deter herbivores. Plants maintain an ability to sense when they have an injured area and induce a ...
Biological control agents of plant diseases are most often referred to as antagonists. Biological control agents of weeds include seed predators, herbivores , and plant pathogens. Biological control can have side-effects on biodiversity through attacks on non-target species by any of the above mechanisms, especially when a species is introduced ...
