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

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

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.

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

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

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

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

The aim of the present work is to assess the usefulness of pteridines in determining the age of adults of P. scutigera.

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.

To understand, and predict, Heliothis dynamics on cotton, along with changes in resistance levels, we must understand their dynamics on other hosts and the patterns of movement from these to cotton.

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

SIRATAC users have the option early in the season of using standard thresholds or dynamic thresholds which vary between the standard level and an upper limit.

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 v. Arx (Walker and Nikandrow, unpublished data) was found causing anthracnose on X.

The Siratac system when it was originally conceived had no database system included in the workings of the system.

As the first presentation on this topic I would like to very briefly outline the major advantages of producing an early crop.

You are all aware that currently there are three varieties available commercially: Siokra 1-2, Sicala 3-1 and DP90 (Deltapine - Acala) .

It was once a commonly held belief in central Queensland that, because the potential cotton growing season was a long one, earliness was not an important management consideration.

Seedling diseases include seed rots, pre and post emergent damping 9ff and root pruning. Numerous fungi can be responsible although Rhizoctonia sp., Pythiwn spp. and Fusarium spp. are the most important.

To the question "Can nutrition affect earliness?" the answer must be a definite Wes". Further, it will be just as important a factor as irrigation or pest management.

This Overview has been compiled after talking with a limited number of growers from most districts, and as could be expected there were some opposite opinions expressed.
