Plant Agriculture transfer of stress-, herbicide-, or pest-resistance traits to crop species, development of plants with the increased abilities of photosynthesis or nitrogen fixation, development of biological insecticides and nonice nucleating bacterium. [Pg.3]

Unlike many chemical insecticides, the NPVs used as biological insecticides do not contaminate the environment. They are a superb nonpolluting, biodegradable insecticide. In most... [Pg.61]

As soon as research results show conclusively that a Baculovirus is a safe and effective biological insecticide and a candidate for further development, two important questions must be answered a) Can the virus be produced in large scale and at an acceptable cost, and b) What are the most suitable methods for potency standardization of the final commercial product ... [Pg.62]

There are six papers la this section. They deal with biological insecticide formulations (Ward), water dispersible granules (Wright and Ibrahim), analysis of formulations for quality control and identification of toxic contaminants (Plimmer), identification of surfactant metabolites (Stolzenberg et al.), electrostatic spraying (Law) and compatibility and tank-mix testing (Tarwater). [Pg.7]

Commercial preparations of B.t.. obtained through conventional fermentation techniques, have been used for more than two decades as biological insecticides (I). They exhibit desirable properties such as high insect toxicity and environmental safety. B.t. does not affect non-target insects and is completely nontoxic to vertebrates. Nevertheless its use has been limited due to high production costs, limited stability in field conditions and a too narrow insecticidal spectrum. The insecticidal activity of B.t. relies in the crystalline inclusions which are produced upon sporulation. The crystals contain insecticidal proteins, delta-endotoxins, which affect the midgut epithelium of sensitive insects. The exact mechanism of their toxic activity is still unknown. [Pg.274]
