Fungicide
From Wikipedia, the free encyclopedia
Fungicides are chemical compounds used to prevent the spread of fungi in gardens and crops, which can cause serious damage to the plants. Though oomycetes are not fungi, they use the same mechanisms to infect plants[1] and therefore in phytopathology chemicals used to control oomycetes are also referred to as fungides. Fungicides are also used to fight fungal infections.
Fungicides can either be contact or systemic. A contact fungicide kills fungi when sprayed on its surface. A systemic fungicide has to be absorbed by the plant. One example is the QoI.
It is useful in agriculture to avoid fungus growth as many fungal pathogens can greatly reduce yield and thus profits.
Fungicide residues have been found on food for human consumption, mostly from post-harvest treatments.[2]. Some fungicides are dangerous to human health, such as Vinclozolin, which has now been removed from use.[3]. However most fungicides are no more toxic to humans than salt.
Like other pesticides, fungicides can induce pesticide resistance. Equivalently, antifungal drugs can induce drug resistance.
