Book Description
The bean crop of the Southwest suffers severe injury from the bean ladybird, which sometimes ruins entire crops. It is restricted to beans for food and attacks all kinds. Both beetles and their larvæ devour all parts of the plant -- leaves, flowers and pods -- but the chief injury is to the foliage. The pest can be controlled in small areas by hand-picking the overwintered beetles and by brushing the larvæ or young from the plants during hot, dry weather. On a larger scale it may be controlled by spraying with arsenite of zinc, arsenate of lead, or arsenate of lime. Clean cultivation should be practiced and early and late planting." -- [2]

The Longleaf Pine Forest
Author: Kenneth W. Outcalt
Publisher:
ISBN:
Category : Forest ecology
Languages : en
Pages : 28
Book Description
Longleaf pine cornunities were once the most prevalent ecosystem in the Southeastern United States. Conversions of land to agricultural and urban uses and replacement of longleaf with other pine species following logging have drastically reduced the area occupied by longleaf pine. Although longleaf communities can still be found over most of its original range, the species occupies less than 5 percent of its historical acreage, Private individuals own most of the remaining longleaf pine, except in Florida. The private sector is where most losses in longleaf acreage have occurred over the last decade. Because prices and the number of sawtimber-sized trees are increasing, potential harvests in the near future will probably be high. If appropriate information and incentives are not in place, losses of longleaf from private lands could substantially increase.
