AZADIRACHTIN is a terpinoid chemical !ound in Meliaceous trees (e.q. White Cedar) but especially concentrated in the seeds of the Neem tree (Azadirachta indica).

The successful application of Agrochemicals involves an understanding of the:- target, product, equipment, droplet behaviour, and the environment.

One of the aims of this project is to assess the N fertiliser requirements of cotton under more enlightened tillage systems currently being adopted.

Although resistance to insecticides was a well-documented phenomenon, pest control operators have merely switched from less effective insecticides to newer more potent compounds and thereby kept ahead of the resistanc

Chemical Farming implies the use of chemicals for the control of insects, weeds and diseases.

In recent years the use of agrochemicals, often referred to as pesticides, has become an increasingly controversial topic.

One of the important characteristics elevating Heliothis spp. to major pest status is the ability to enter facultative diapause.

This can cover an enormous area because not only does technology intrude into every aspect of growing a crop, by the view of it can change drastically with each different farmer.

My objective has been to construct life tables describing Heliothis egg and larval survival on the major crops of the Darling Downs over several seasons.

I have to tell you now that I will not be presenting such a perspective.

Biological control represents one alternative to insecticides. The Cotton Research Council (CRC) has funded a project to study native egg parasites of Heliothis.

Genetic engineering involves the agronomic improvement of crop plants through the introduction of new genetic information (genes) originating from other organisms.

The study reported here concentrated. On these sap-suokinq bugs, which were reputed to damage seedling and early-squaring cotton

Your committee has asked me particularly to focus on the technological needs of the industry. As a background to this it's worth talking briefly about the research councils and their evolution.

BACILLUS THURINGIENSIS use as an insecticide for 25 years despite formidable competition from conventional insecticides is largely due to its safety and compatibility.

Most herbicides are complex molecules and their decomposition often requires several different chemical conversions, each mediated by a variety of organisms.

One such form is biological control, which relies on the use of natural pathogens and parasites to control the pest species.

The fungus Colletotrichum orbiculare(Berk. et Mont.) v. Arx (Walker and Nikandrow, unpublished data) was found causing anthracnose on X.
