Both lantana and common purslane are weed pests in some crops. Common purslane root exudates inhibited soybean growth but showed stimulation in other bioassays reported in this paper. This may be a concentration and bioassay species dependent effect, since the effect of any toxin varies according to concentration and bloassay species (12). Lantana root exudates showed the strongest inhibitory effect on soybean growth of any of the species tested. Lantana is not found in soybean fields but is a weed pest in some areas in citrus orchards. Holm (13) included lantana, johnsongrass, and cogongrass in his list of the worst weed pests in the world. 

Bahiagrass reduced okra germination at 72 and 96 hours. Lantana reduced beet germination at 48 and 72 hours. 

Starch granules from different plants including algae Chara coralline (Mizutani et al. 2000), flowering plant Lantana camara (Cox et al. 2005), corn (Chu et al. 2001), potato, rice, and tapioca can be considered as nonlinear optical materials.

Other workers have examined the use of insects to consume troublesome weeds. Again there are problems associated with the selection of an insect that is specific to the weed and has no other disadvantages such as the sensitivity of some people. Such systems are unlikely to become widely used in agriculture but do find small niche markets, especially with the home gardener. Workers in South Africa have evaluated several insects for the control of the invasive weed Lantana camara and the aquatic fern Salvinia molesta with encouraging results.9 The grass carp has also been recommended for control of a number of submerged aquatic weeds. 

Fig. 5.3. Odor changes that track floral color changes. Gas chromatography-mass spectrometry total ion chromatograms of floral headspace collected from young (upper trace) and old (lower trace) flowers of Lantana montevidense. Peaks 1,8,10, and 12 are metabolites of linalool (peak 3), all of which decrease dramatically with floral age and color change. Sesquiterpene hydrocarbons (peaks 4, 5, 9, and 11) show comparable decreases over time. Peaks 2, 6, 7, 13, and 14 are oxygenated aromatics and are present only in newly opened, rewarding flowers. Insert mass spectra highlight loss of phenylacetaldehyde ( peak 7) taken from young (a) and old (b) flowers. (M. R. Weiss and R. A. Raguso, unpublished data.)...

There arc a few temperate representatives of this family, which is otherwise tropical. It is best known, perhaps, for leak and weedy plants (Lantana).

Insects This method has received little attention as a means of combating weeds in citrus. Habeck (1977) showed that insects could be used against largeleaf lantana and stranglervine. A number of leaf-mining beetles have been used successfully in Australia and Hawaii to control largeleaf lantana, which is a major weed in Florida citrus orchards (Tucker and Singh, 1983). 

Maximum absorbance and relative molecular weights (M.W., kDa) of proteins modified in bean and tomato by aqueous extract of Lantana camara. The number of each protein corresponds to that on the 2D-gels (Fig. 14.2). Values in bold correspond to increased proteins.
