This paper considers some recent research on mirids, in particular thresholds, sampling and control of the green mirid.

I would like to focus on what I believe to be some of the most important issues now and in the future for the irrigation industry and, in this particular instance, the cotton industry - - whilst however keeping in min

International trade in organic produce is now estimated to be worth around US$40billion per annum Of this, Australia produces in the vicinity of $40m each year2 and it is expected to become nearer to 10 percent of tot

Use of fertilizers and insecticides in cotton production has increased to the extent that cotton production is losing its profitability against other field crops.

Insects in cotton fields form a diverse and volatile community. Room (1979) collected some 500 species of insect (plus spiders) in Australian cotton fields. Some (the ones we notice most) are pests.

Thrips are important pests in Australian cotton and are also key predators of spider mites.

The specific aims of this project are to: I) establish a repeatable field survey scheme of key soil variables influencing cotton production in the lower Namoi, Gwydir and Macintyre valleys; 2) obtain a quantitative st

Since the late 1940s, synthetic herbicides have provided effective and economical control of many weeds.

It is probable the I.P.M. of the future will rely heavily on predators, parasites, pheromones, food sprays and deterrents, and that these systems will be developed at least in part in these organic fields.

Various parasitoids are active on cotton crops from early seedling growth right through to defoliation.

A vision guidance system has been designed, built and commissioned which steers a tractor relative to the rows of a crop such as cotton .

The HEAPS (HE.licoverpa d.rmigera and l!.imctigera Simulation) model embodies all of our current knowledge on the ecology of Helicoverpa within cotton cropping regions.

Permanent beds are becoming popular in the cotton industry, but problems remain with matching equipment and tyre sizes to the beds and furrows.

Premature senescence caused by potassium deficiency has been most severe on soils that are considered deficient or marginal in potassium for cotton growth ie.

We have conducted in field experiments for the past two years to develop a food product that can be used to attract, conserve and augment natural enemies especially predatory insects in cotton fields and utilized them

There are both anecdotal and well documented reports indicating that unsprayed cotton can be profitable.

The Total Catchment Management ("TCM'') philosophy was formalised in NSW in 1980 with the passing of the Catchment Management Act which provides a clear legislative base for the operation of TCM Committ

The overall aim of the project is to examine the response of cotton to Pix (mepiquat chloride) under different growth rates in the Macquarie Valley.

Watertable rises resulting from irrigation are evident in several areas in the Murray Darling Basin, with groundwater level rises of up to 70 cm per year being reported in the Riverina and 50 cm in the Lower Macquarie

In this article I will chiefly focus on the this problem on soils with adequate levels of soil potassium.
