T he use of plants as crops to produce food, fiber, and other products has an amazing record of environmental safety. The greatest risk with any plant deliberately introduced into a new environment is its potential for inva-siveness beyond the planted area—to become a weed—but even here crop plants have an outstanding record of safety. Crop plants typically must be managed as " weedy " voluntee...

Aphid is assumed one of the most severe pests attacking wheat causing harm to plants either directly by sucking juice or indirectly as a vector diseases.

Abstract
 Bintaro is a plant that contains poison in all parts of the plant. Cardiac glycoside compounds contained plants can be used as biopesticides to repel rats. Rat pests are one important rice difficult control, so production always decreases. Therefore it necessary look for an effective, efficient and environmentally friendly control technology, namely by using extracts which able b...

The 'high-dose-refuge' (HDR) strategy is widely recommended by the biotechnology industry and regulatory authorities to delay pest adaptation to transgenic crops that produce Bacillus thuringiensis (Bt) toxins. This involves cultivating nontoxic plants (refuges) in close proximity to crops producing a high dose of Bt toxin. The principal cost associated with this strategy is due to yield losses...

Advances in transgenic plants expressing Bacillus thuringiensis (Bt) insecticidal gene(s) offer a promising alternative to traditional insecticides for control of lepidopteran pests on important cruciferous vegetable crops such as cabbage and cauliflower. A public-private partnership, the Collaboration on Insect Management for Brassicas in Asia and Africa (CIMBAA), was formed in 2005 with the g...

Bacillus thuringiensis (Bt) is a useful alternative or supplement to synthetic chemical pesticides in agriculture, forest management, and control of mosquitoes and some other biting insects. When modified Bt cry genes are inserted into a plant species (e.g., corn, cotton, potato, canola, rice), the plant expresses active larvicidal proteins in its tissues. The toxins continue to be synthesized ...

Many newly set pineapple plants die from pineapple mite, Dolichotetranychus floridanus (Banks), infestations. Other infested plants remain small and produce very little or no fruit. Although this mite infests plants of all ages, it is a serious pest only on young ones. Nursery stock distributed or sold by nurserymen, or used by fruit producers, should be free of mites and other pests. Control o...
