Penetration of packaging films: Film materials used for food packaging tested for resistance to some common stored-product insects
by Paul D. Gerhardt, David L. Lindgren
| Full text HTML  | PDF  
A nontransparent laminated film containing aluminum foil proved relatively resistant to insect penetration– but not insect proof–in tests of film materials used for packaging dried fruits, nuts, candies, cereals, grains, meats, cheese, and other food products.

Study of systemic insecticides: Location and amounts of residue in plant tissues determined with aid of radio-phosphorus tracers
by R. L. Metcalf, R. B. March, T. R. Fukuto
| Full text HTML  | PDF  
The systemic insecticides – schradan – octamethyl pyrophosphoramide and demeton or Systox–O,O-diethyl O-ethyl-beta-mercaptoethyl thionphos-phate–and their derivatives have shown unusual promise for the control of mites and aphids and other sucking insects of a variety of agricultural crops.

Biuret, toxic form of nitrogen: Soluble nitrogen compounds are not of equal value as fertilizers as shown by tests with citrus and avocado
by A. R. C. Haas, Joseph N. Brusca

Fungi and shell bark of lemon: Complex disorder of bearing lemon trees studied to establish role of fungi and control of the disease
by E. C. Calavan, L. G. Weathers
| Full text HTML  | PDF  
The best and cheapest shell-bark control–the only real control–is the use of resistant lemon selections on good root-stocks.

Crop rotation and citrus: Cropping old citrus soil to other plants studied to learn effect on the growth of citrus replants
by J. P. Martin, J. O. Ervin
| Full text HTML  | PDF  
When some plants are grown in the same soil for long periods of time, organisms detrimental to the species develop and reduce the growth of the plants or replants, if perennials, and of subsequent crops, if annuals.

Variable leaf punch: Improved foliage sampling tool aid in studies with unit leaf sections
by Gordon L. Smith, Donald E. Little
| Full text HTML  | PDF  
Developed for taking unit area samples of cotton leaves, an improved leaf punch has advantages for the entomologist, the plant pathologist, and for others working in plant sciences.

Two maior pests on apples: Spider mite and woolly apple aphid infestation in late summer damaging to apples for processing
by Harold F. Madsen, Arthur D. Borden, Edward C. Koch
| Full text HTML  | PDF  
Acaricieles–with long residual value– prevent late season buildup of European red mite and 2-spot mite populations on apples, but control of woolly apple aphid usually requires the inclusion of an aphi-cide in the mite treatment.

The orange banana squash–which originated as a selection from the regular or Pink Banana variety–differs from the parent variety in many respects.
