throughout the world in 1999. The most commonly used class of pesticides was herbicides (36%), followed by 'other pesticides' (which includes nematicides, fumigants, rodenticides, molluscicides, aquatic and fish or bird pesticides, other miscellaneous conventional pesticides, plus other chemicals used as pesticides, such as sulfur and petroleum)(29%), insecticides (25%), and fungicides (10%).

The estimated U.S. use of pesticides in 1999 is provided in Figure 11.2. It has been estimated that 5.7 x 108 kg of pesticides were used in the U.S. in 1999,

Insecticides 5.9 x 107 kg

led by herbicides (43%), 'other pesticides' (41%), insecticides (10%), and fungicides (6%).
