They can also be used to control internal seed-borne fungal pathogens as well as fungal pathogens on the seed surface. Many biofungicidal products show capacities to stimulate plant host defense and other physiological processes that can make treated crops more resistant to stresses.
Fungi, plants and herbivore population sizes can have a cyclical predator-prey pattern. Infection rates of endophytic fungi in plants tend to increase with rise in grazing pressure. [111] If endophytic fungi becomes highly prevalent in grazer food sources, it can even lead to population crashes in grazing animals. [111]
The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. [1] [2] The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties.
The plants soon begin to wilt and quickly dry out in the sun. Plants can burn within hours of exposure to these herbicides. [16] In contrast, Photosystem I inhibitors such as diquat and paraquat work by entering plant cells and immediately diverting electrons away from photosynthetic chain, poisoning photosynthesis.
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]
Leaves, stems, and green unripe fruit of the tomato plant also contain small amounts of the poisonous alkaloid tomatine, [36] although levels are generally too small to be dangerous. [36] [37] Ripe tomatoes do not contain any detectable tomatine. [36] Tomato plants can be toxic to dogs if they eat large amounts of the fruit or chew the plant ...
There are many ways in which a plant can become infected by a bacterial soft rot. They can be host to the bacteria either by being infected as seed, or from direct inoculation into wounds or natural openings (stomata or lenticels) in mature plants, which is most common. But, when a plant is infected and the conditions are favorable, the ...
The best way to control this disease is to take preventative measures, such as sterilizing pruning tools so as to avoid infecting new plants. Performing mandatory inspections of nursery stock and rejecting infected plants as well as not planting susceptible plants in infected fields are also valuable practices.
