Abstract
Foliar spray treatments with zinc, copper, manganese, iron and boron on Chinese garlic grown in a field at kaha, kalubia Gov. during 2005-2006 and 2006-2007 growing seasons was performed. All treatments significantly reduced downy mildew, purple blotch and rust foliar diseases of garlic. Highest disease reductions and increase in yield were mostly detected with zinc, manganese, iron and boron once sprayed at the rate of 100 g/fed 60 days after planting. While the most effective copper treatment for controlling diseases was detected at the rate of 50 g/fed twice sprayed 60 followed by 90 day intervals after planting. Mean percentages of diseases reduction obtained with the fore-mentioned treatments reached 36.3%, 60%, 65.5% for downy mildew, purple blotch and rust diseases, respectively. While mean increase in garlic yield reached 55% over control treatment. Other treatments were less effective.
