RECIPE #46 TOMATO LEAF SPRAY Categories: Garden, Bugs Tomato Leaf Spray: This one I know is to be used on tomato leaves... Pack 1 qt of rhubarb leaves in a sturdy, heat resistant bucket, pour 1 qt boiling water over the leaves. Let mixture steep 1 hr. Strain through a cloth, squeezing the leaves to remove as much liquid as you can. Dilute mixture in water before using... Doesn't say how much... I tried it and I diluted with 1 pt of water and added to hose end sprayer.. Made leaves healthier, bugs were less of a problem too... -----
