Brittleness and Other Responses of Corn to 2,4-Dichlorophenoxyacetic Acid

Physiological and Morphological Responses of Barley to 2,4-Dichlorophenoxyacetic Acid.

Selective herbicides have been used for weed control since the turn of the century, but the use of 2,4-dichlorophenoxyacetic acid (2,4-D.) has developed during the past decade. This chemical is valuable because numierous broadleaved weeds are susceptible to low rates of application and mnany agronomic crops are tolerant to these small dosages. Barley has been considered to be one of the relativ...

Effect of 2,4-dichlorophenoxyacetic Acid on Meristematic Tissues of Corn.

In recent years the use of 2,4-dichlorophenoxyacetic acid (2,4-D) as a selective herbicide has become increasingly important in the production of small grains and corn. Yield reductions due to direct injury to the crops are usually small. However, severe yield reductions have occurred occasionally when 2,4-D was used at herbicidal dosages during certain stages of crop growth. Corn plants spraye...

Comparative Effects of 2,4-Dichlorophenoxyacetic Acid on Nitrate Metabolism in Corn and Cucumber.

Since the first demonstrations of the herbicidal action of 2,4-D, many possible mechanisms for the toxicity have been proposed. These include changed respiratory metabolism, abnormal cellular proliferation, and interference in nucleotide metabolism. It has further been recorded that nitrate metabolism is altered in response to applied 2,4-D. In many broad leaved weed species (14, 5) and in the ...
