The value of the almond crop, and the basis of returns to growers—averaged for 1943, 1944, and 1945—place the almond seventh, on the list of all California deciduous tree fruits and nuts.

A new organic compound—officially named Parathion by the United States government, and known chemically as O, O-diethyl-O-p-nitrophenyl-thiophosphate and to research field men as 3422—was tested last season on deciduous fruit trees with excellent success.

It is more difficult to grow good trees on old citrus soil than on soil which has never been cropped to citrus.

Seedless Calimyrna figs may be produced without the use of male or caprifigs, by spraying the trees with a solution of indolebutyric acid at caprification—pollination—time.
