Fungicide
From Wikipedia, the free encyclopedia
Fungicides are chemical compounds used to prevent the spread of fungi or plants in gardens and crops, which can cause serious damage resulting in loss of yield and thus profit. 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 fungicides. 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.
The majority of Fungicides that can be bought retail are sold in a liquid form. The most common active ingrediant is Sulphur, running at 0.08% for the weaker concentrates, and has high as .5% for the more potent fungicides. In powdered form, the concentration usually runs around 90%, and is very toxic.
Other active ingrediants in different brands include Neem oil, rosemary oil, Bacillis Subtilis, and Jojoba oil.
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]
Like other pesticides, fungicides can induce pesticide resistance. Equivalently, antifungal drugs can induce drug resistance.
