Bootlace fungus

Common name for Armillaria mellea. Bordeaux mixture

The first, and also the most spectacularly successful, of all man-made fungicides, discovered in Bordeaux, France, by Millardet, in 1882. The mixture is prepared by mixing a solution of copper sulphate with freshly slaked lime. This fungicide saved the French wine industry from ruin by the newly introduced downy mildew (Peronospora viticola), and it also controlled potato blight, caused by Phytophthora infestans. Borlaug, Norman

Breeder of the miracle wheats and winner of the 1970 Nobel Peace Prize. Boron

Boron is an important plant nutrient although its physiological function is poorly understood. Boron deficiency causes many growth distortions. If boron deficiency is suspected, a specialist should be consulted.
