Red, yellow, blue and green labels.
Toxicity labels viz; red label, yellow label, blue label and green label are mandatory labels employed on pesticide containers in India identifying the level of toxicity of the contained pesticide. The schemes follows from the Insecticides Act of 1968 and the Insecticides Rules of 1971.
The labeling follows a general scheme as laid down in the Insecticides Rules, 1971, and contains information such as brand name, name of manufacturer, name of the antidote in case of accidental consumption etc. A major aspect of the label is a color mark which represents the toxicity of the material by a color code. Thus the labelling scheme proposes four different colour labels: viz red, yellow, blue, and green.
|Label||Name||Level of toxicity||Oral lethal dose mg per kg body weight of test animal||Listed chemicals|
|Red label||Extremely toxic||1-50||Monocrotophos, zinc phosphide, ethyl mercury acetate, and others.|
|Yellow label||Highly toxic||51-500||Endosulfan, carbaryl, quinalphos, and others.|
|Blue label||Moderately toxic||501-5000||Malathion, thiram, glyphosate, and others.|
|Green label||Slightly toxic||More than 5000||Mancozeb, oxyfluorfen, mosquito repellant oils and liquids, and most other household insecticides.|
The toxicity classification applies only to pesticides which are allowed to be sold in India. Some of the classified pesticides may be banned in somes states of India, by decision of the state governments. Some of the red-label and yellow-label pesticides were banned in the state of Kerala following the Endosulfan protests of 2011.
