SummaryField studies were conducted to determine if season long weed control could be achieved by combining the use of an herbicide with the natural allelochemicals produced by cultivated sunflower (Helianthus annuus L.). The weed biomass was reduced equally in plots planted with sunflowers, whether or not the herbicide was applied in each of 4 years. Weed control diminished the second year in all plots that received the same treatments as had been applied the previous year. This diminished… 

Sunflower Allelopathy for Weed Control

The allelopathic potential of sunflower (Helianthus annuus L.) can be used for controlling weeds in sunflower and other crops and cultivating sunflower genotypes that could express an allelopathy activity.

Sunflower allelopathy for weed control in agriculture systems

It is conceptualized that the inclusion of such oilseed crops before the rice crop in the rice-wheat rotation may provide satisfactory weed control in the succeeding rice crops and may minimize the use of herbicides.

Role of Allelopathy in Weed Management for Sustainable Agriculture

Use of smothering crops as allelopathic strategies could provide weed control, both in summer and winter crops. Although, these crops do not provide complete weed control they can manage weed

Potentials for exploiting allelopathy to enhance crop production

Under greenhouse conditions, joint application of low levels of atrazine, trifluralin, alachlor, or cinmethylin with a phenolic allelochemical showed that these two categories of inhibitors acted in concert to reduce plant growth.

Effect of sunflower (Helianthus annuus L.) on the suppression of some summer weeds at the Field Station of the University of Zambia

Weeds present a major challenge to crop production and need to be controlled. Several methods of weed control exist but they have proved to be less than successful especially in the tropics;

Reducing the Risks of Herbicide Resistance: Best Management Practices and Recommendations

Herbicides are the foundation of weed control in commercial crop-production systems. However, herbicide-resistant (HR) weed populations are evolving rapidly as a natural response to selection

Phytotoxicity of sunflower (Helianthus annuus L.) and its allelopathic potentiality on growth and yield attributes of Parthenium hysterophorus

Results suggest that sunflower green manuring and its rhizosphere soil has herbicidal potential and may be utilized as biological control of weeds for sustainable agriculture and environmental safeguard.

Allelopathic Effects of Sunflower on Some Operative Components of Cotton

ABSTRACT: In order to investigate the allopathic effects of sunflower on cotton germination, this research was done in the form of a quite accidental plan with 3 replications. The density of the

Response of 33 weed species germination to allelocompounds contained in sunflower (Helianthus annuus L.)

In response to allelocompounds derived from sunower, the germination of the weeds, with few exceptions, was delayed and reduced, with complete inhibition in some cases, which depended on the weed species and on the concentration used.

Alternative Weed Control Methods: A Review

Weed interference is one of the most important limiting factors which decrease crop yields and consequently global food production and there was a shift in control methods toward high input and target-oriented ones in the early 1930s.

Competitive and Allelopathic Effects of Sunflower (Helianthus annuus)

In the field, soybeans required 4 to 6 weeks free of sunflower competition for maximum yield, and in greenhouse studies, soybean height, fresh weight, and dry weight were significantly reduced at certain sunflower and soybean densities and levels of competition.

Sunflower hull material from Sunflower (Helianthus annuus L.) was unsuccessful as an amendment in potting mixtures because of inhibition to top and root growth. Aqueous and methanol extracts from
