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. [citation needed]
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 bacteria tend to be seed-borne, and are dispersed between plants by rain splash. [18] Although it is a plant pathogen, it can also live as a saprotroph in the phyllosphere when conditions are not favourable for disease. [19] Some saprotrophic strains of P. syringae have been used as biocontrol agents against postharvest rots. [20]
It is presumed that this disrupts the binding of the fungicide to the protein, rendering the fungicide ineffective. Upregulation of target genes can also render the fungicide ineffective. This is seen in DMI-resistant strains of Venturia inaequalis. [10] Resistance to fungicides can also be developed by efficient efflux of the fungicide out of ...
In contrast to biotrophs, hemibiotrophs have dual life-styles. The initial biotrophic life-style of hemibiotrophs causes minimum damage to the plant tissues, while the fungus obtains nutrients from living plant tissues [8] Hemibiotrophic fungi require living plant tissue to survive to complete their life cycle.
For formulations with pesticides, direct application to seeds can be environmentally more friendly, as the amounts used can be very small. [2] Color makes treated seed less attractive to birds, and easier to see and clean up in the case of an accidental spillage. [3] A thick coating can improve handling, by hand or by machine.
There were outbreaks of dog food containing aflatoxin in North America in late 2005 and early 2006, [38] and again in late 2011. [39] Mycotoxins in animal fodder, particularly silage, can decrease the performance of farm animals and potentially kill them. [40] [4] Several mycotoxins reduce milk yield when ingested by dairy cattle. [40]
