This 3 year study examined the relationships between catches of Heliothis adults in monitoring traps and the abundance of eggs on cotton crops.

* Testing various versions of SIRATAC on a commercial scale. * Ptoviding a database of the response of cotton to damage. *Comparing the response of the new varieties Siokra and DP90 with DP61.

To determine the various factors affecting the loss of activity of insecticides on cotton over time.

The experiments reported here investigated the influence of high or low concentrations of nitrogen, phosphorus and potassium on the multiplication of X.campestris pv. malvacearum in cotton leaf tissue.

I will first mention some of the features distinguishing "Australian Conditions".

This paper reports the initial results from testing different versions of the SIRATAC pest management system in the Namoi Valley for two seasons the experiments were designed to investigate the ability of the program

Over the last quarter of a century, as problems in relying completely on pesticides for control of insects have become apparent, there has been renewed interest in the possibility of breeding cottons less susceptible

One of the notable features of the SIRATAC pest management system is that its use followed extremely quickly on its initial formulation.

This subject is very relevant to the Australian Cotton Growing Industry as the most common complaint against our major seed variety, DPL 61, is that this growth has a lower breaking strength when it is produced in Aus

In response to the development of resistance to pyrethroids by Heliothis armigera in 1983, an Insecticide management strategy was devised.in an attempt to prolong the field effectiveness of this and indeed, the other

In agriculture we often hear reports of new wonder varieties that are about.to revolutionise agriculture, yet when these varieties are released, if indeed they are released, they seem to fall far short of the publicit
