Phytotoxicity of four photosystem II herbicides to tropical seagrasses. [PDF]

open access: yesPLoS ONE, 2013
Coastal waters of the Great Barrier Reef (GBR) are contaminated with agricultural pesticides, including the photosystem II (PSII) herbicides which are the most frequently detected at the highest concentrations. Designed to control weeds, these herbicides

Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]

open access: yes, 2009
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Field Evaluation of Herbicides on Small Fruit, Vegetable, and Ornamental Crops, 1997 [PDF]

open access: yes, 1999
Growers generally use herbicides to efficiently produce high-quality fruit and vegetables for processing or fresh market sales. Due to the smaller acreage of these crops compared to major field crops, fewer herbicides are registered for use in fruit and ...
