“…Woldu and Saleem (2002) observed that this species is present in natural grazing grasslands in Ethiopia regardless of the varying grazing intensity. Reports from Europe affirmed G. parviflora as a common and serious weed in tomato crops in Poland and Slovenia (Tei et al . 1999).…”

Galinsoga parviflora, an annual dicot species of the family Asteraceae, is a common herb that is often found in disturbed habitats and agricultural areas in many parts of the temperate and subtropical regions of the world. It is a native of tropical America and the center of its origin is thought to be the mountainous area of Central America. Galinsoga parviflora is considered to be a common weed in several crops of major importance, such as wheat, corn, cotton, tobacco, sugarbeet, tomato, pepper, potato, bean, onion, cabbage, garlic, coffee, citrus, banana, and strawberry; it is frequently found in gardens and uncultivated areas. It succeeds particularly in moist soils and it is favored by a long photoperiod and high light intensity. The significant features of the plant, such as the lack of seed dormancy, rapid growth and development, early flowering, many generations per growing season, production of a great number of seed in a wide range of environmental circumstances, and the ability for easy vegetative reproduction under favorable conditions predispose the plant to be a troublesome weed.These features allow the easy distribution and rapid establishment of the weed in large populations, a fact that often makes this weed difficult to control. Galinsoga parviflora competes strongly, particularly with irrigated crops of short height, and it might also hinder crop harvest. The management of G. parviflora can be achieved by manual weeding, repeated soil cultivation, crop rotation, mulching, and herbicide application. The plant is reported to be edible and is used also for medicinal purposes.

Field and greenhouse experiments were conducted in 2007 and 2008 to evaluate weed competitiveness and herbicidal sensitivity of grafted tomatoes. Three weed interference levels were established in the field by imposing different weeding pressures.Results indicated that grafting of tomato seedlings did not increase the ability of plants to suppress weeds over self rooted plants.Grafted tomatoes had more vigorous growth and fruit yield compared to self rooted tomatoes across all weed levels. Weeds were found to have more prominent adverse effects on tomato productivity, but had less adverse effects on plant growth. Greenhouse experiments were conducted to detect herbicidal sensitivity of grafted and self rooted tomatoes towards metribuzin and sethoxydim herbicides. The experiments revealed that grafted tomatoes showed a relatively higher herbicidal sensitivity than self rooted seedlings. Grafted plants probably were less able to metabolize and detoxify high herbicide rates whenever variations in plant height or dry matter accumulations were detected in the experiments. Researchers and producers should be aware of this newly observed sensitivity when designing herbicide application programs for weed management in grafted crops.

“…Phytotoxic effects observed at 1 µL/mL of ginger essential oil in P. oleracea (45.35%) and L. multiflorum (46.67%) (Table 2)—weeds commonly affecting tomato crops [55]—were not reproduced in tomato germination, but, unfortunately, both hypocotyl and radicle development were significantly inhibited (Table 4, Figure 3A). These results agree with those of previous work in which seed germination of soybean was not inhibited by the aqueous extract of ginger rhizome at the doses assayed, whereas the hypocotyl and radicle length were reduced at the higher doses applied [56].…”

Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, Echinochloa crus-galli, Cortaderia selloana, and Nicotiana glauca) and food crops (tomato, cucumber, and rice) were studied. Forty-one compounds, accounting for a relative peak area of 87.7% and 94.6% of turmeric and ginger essential oils, respectively, were identified by Gas Chromatography–Mass Spectrometry analysis. Ginger essential oil with α-zingiberene (24.9 ± 0.8%), β-sesquiphelladrene (11.7 ± 0.3%), ar-curcumene (10.7 ± 0.2%), and β-bisabolene (10.5 ± 0.3%) as the main compounds significantly inhibited the seed germination of P. oleracea, L. multiflorum, and C. selloana at the highest dose (1 µL/mL) assayed, as well as the hypocotyl and radicle growth of the weeds. Turmeric essential oil with ar-turmerone (38.7 ± 0.8%), β-turmerone (18.6 ± 0.6%), and α-turmerone (14.2 ± 0.9%) as principal components significantly inhibited the seed germination of C. selloana and hypocotyl and radicle growth of weeds (the latter in particular) at the highest dose, whereas it did not affect either the seed germination or seedling growth of the food crops. Turmeric essential oil can be an effective post-emergent bioherbicide against the tested weeds without phytotoxicity to crops.
