Oil Components

Essential oils are a plentiful source of plant compounds for potential use in the development of natural herbicides. With this in mind, the phytotoxicity of ten major essential oil components of lavender (Lavandula angustifolia Mill.) on the weed species bristly foxtail (Setaria verticillata (L.) P. Beauv.) was determined using a perlite-based Petri-dish bioassay. Their phytotoxicity was also compared with that of well-known phytotoxic essential oil components (carvacrol, thymol, carvone and eugenol) of oregano (Origanum vulgare L.) and clove (Syzygium aromaticum (L.) Merr. & L.M. Perry) essential oils. Potential synergistic or antagonistic effects between carvacrol or eugenol with other components of lavender essential oil were investigated. Regarding the most phytotoxic components, terpinen-4-ol at 80 nL/cm3 completely inhibited the germination and root length of bristly foxtail, displaying similar phytotoxicity to carvone and thymol. Like carvacrol, lavandulol and linalyl acetate caused total (100%) germination and root length reduction of bristly foxtail at 160 nL/cm3, while the same effect was achieved by lavandulyl acetate at 320 nL/cm3. A synergistic effect was also observed when carvacrol or eugenol were combined with ocimene, 3-octanone, ?-terpineol or terpinen-4-ol. Focusing on the development of alternative weed control strategies, lavender essential oils containing high concentrations of terpinen-4-ol, lavandulol or linalyl acetate could be useful for the production of natural herbicides. These essential oil components combined with selected oregano or clove essential oil components, increase phytotoxicity and weed control due to the synergistic effect observed when in mixture.

Successful Invader

Abstract S. verticillata is listed by Holm et al. (1979) as a 'serious' or 'principal' weed in 11 countries in Europe, Asia, Africa, South America and the Pacific. From its origins in Europe and perhaps Africa, it has been accidentally introduced to many other countries across the world. It is often listed as one of the two or three most important weeds in a wide range of crops, within and outside its native range, and it can also become dominant in grassland. The combination of ready dispersal by its 'sticky' seed and seed-heads, and its C4 physiology and rapid growth make it an extremely successful invader. It adapts to local conditions rapidly and has developed resistance to atrazine and other herbicides.

A study was conducted to determine preference intake and relative palatability indices of tanniniferous Acacia karroo fed to 5 growing male Pedi goats with an average body weight of 19.81 ± 1.83kg. Five feeding troughs were provided to each goat and each animal was exposed to all the experimental diets. A cafeteria feeding approach was used, thus, permitting goats free access to the diet of their choice. Acacia karroo (K) was offered in a mixture with Setaria verticillata (S) hay at five different levels: Diet 1: S80K20, Diet 2: S75K25, Diet 3: S70K30, Diet 4: S60K40 and Diet 5: S50K50. The daily relative palatability indexes (RPI) obtained for each diet were subjected to analysis of variance with feeds as treatments and individual animals as replicates in a completely randomized design. Significant differences (P Diet 4> Diet 3> Diet 2> Diet 1. Diet 5 appeared to be the most preferred by goats with an RPI of 96.91%. Palatability indices were positively and significantly (Pand tannin contents. Results of this study indicate that tannin-rich Acacia karroo leaves when fed in a mixed diet can influence preference and intake by Pedi goats. Palatability studies could be used in designing supplemental feeding programs for ruminant livestock in the tropics.

Pot experiments evaluated the efficacy of several preemergence herbicides on three annual grasses that are major problem weeds in most maize growing regions Herbicides evaluated included alachlor metolachlor dimethenamid two formulations of acetochlor and proprietary mixes of acetochlor with atrazine or metribuzin Pots were filled with soil collected from the top 10 cm of seven maize (Zea mays) fields with different cropping histories and seeded with test grasses Herbicides were applied immediately after sowing with a precision glasshouse sprayer Additional seeds were sown at 2weekly intervals for 8 weeks Seedlings were counted 2 weeks after each planting Metolachlor was most effective in controlling summer grass (Digitaria sanguinalis) and rough bristle grass (Setaria verticillata) All herbicides were less effective against the large seeded broom corn millet (Panicum miliaceum) than the other grasses All the herbicides except metolachlor were less effective in soils with a long history of maize growing
