IMPACT OF SILICON IN ALLEVIATING BIOTIC STRESS IN SUGARCANE IN SOUTH AFRICA

摘要: FOR MANY YEARS, silicon (Si) deficiency in crops was relatively unknown and this element widely regarded as non-essential for plant growth. In recent years, Si has emerged an important nutrient a wide variety of including rice, sugarcane, wheat, barley range horticultural crops. With the exception potassium, sugarcane is known to take up more than any other mineral nutrient, with potential accumulate almost 400 kglha Si, 12-month old irrigated crop, Early studies have tended emphasise role alleviating abiotic stress caused by factors such A1 Mn toxicity soils. research increasingly focused on beneficial biotic from pests disease. South Africa, stalk borer Eldana saccharina Walker (Lepidoptera: Pyralidae) been most destnlctive pest over past 30 years huge annual crop losses. This paper documents some outcomes into amendments increasing resistance borer, especially varieties susceptible borer.
