Since 1996, several incidents of poor weed control regarding little seeded canary grass (Phalaris minor Retz.) in wheat (Triticum aestivum L.) production have been reported from the Western Cape. Little seeded canary grass showed indications of resis

The effect of foliar application of molybdenum (Mo) on grain dormancy was examined in six wheat cultivare at four sites. Application of 100 mg L−1 Mo at flag leaf stage significantly increased grain Mo content at all sites and reduced germination a

Wheat which was grown in acid-washed sand and irrigated with a molybdenum-free nutrient solution was treated with various concentrations of molybdenum (Mo) as a foliar spray at the flag leaf stage. At maturity, dormancy levels and abscisic acid (ABA)

Studies on the removal of Acacia longifolia (Andr.) Willd. seed from trays on the soil surface showed that 91,07% of the seed was removed after one week of exposure. Exclusion treatments indicated that ants removed 57,22% of the seed while rodents an

Treatment of barley plants with 2,4-D, when the main tiller apical meristem was in the late vegetative or double ridge stage, resulted in the production of various abnormalities including missing spikes, branched spikes, whorls of spikelets and paire

The Australian Acacia longifolia (Andr.) Willd., owes its success as a weed in South Africa amongst other things to the excessive production of long-lived seed banks under existing stands of the weed. A fairly intense fire (circa 24 900 kW m− 1) wa

The effect of different pre-treatments on the dormancy of the hard-coated seeds of Acacia longifolia Andr. Willd. was determined. A final germination figure of 100% could be obtained with hot water treatments, acid scarification and manual scarificat
