Identification And Control Of Pest Slugs And Snails For Broadacre Crops In Western Australia, Svetlana Micic, Ken Henry, Paul Horne

Bulletins 4000 -

The numbers of slugs and snails have increased in broadacre cropping in Western Australia with the use of minimum tillage and stubble-retention practices. The organic content of paddocks increases under such systems, providing an increased food source especially to young slugs and snails. Soil moisture content is greater over summer leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly the Mediterranean region. They damage plant seeds (mainly legumes), recently germinated seeds, seedlings and leaves and can be a contaminant of grain at harvest.

Incorporating Sheep Into Dryland Grain Production Systems Ii. Impact On Changes In Biomass And Weed Density, P. G. Hatfield, Andrew W. Lenssen, T. M. Spezzano, Sue L. Blodgett, H. B. Goosey, R. W. Kott, C. B. Marlow

Andrew W. Lenssen

Weed control in fallow management to conserve soil moisture and nutrients is the largest variable cost to dryland grain production. Our objective was to compare burning, grazing, tilling, trampling and clipping wheat stubble fields on changes in total above ground biomass and weed density. Treatments were evaluated in three experiments using a randomized complete block design for each experiment with four replications at each site. Contrasts statements were used to make pre-planned comparisons. For experiment 1, treatments were fall tilled, fall grazed, spring grazed, fall and spring combined (Fall/Spr) grazed, and an untreated control. For grazing treatments, five mature ewes …

Protecting Agriculture In 1976 : Three Sides Of An Apb Campaign, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

A quick look at three areas in which the A.P.B. are working with landholders to protect Western Australia from invasion.

Protecting our agriculture and wildlife is not only the APB's job— it is very much the community's job also. Any suspect birds or plants must be reported immediately to the Agriculture Protection Board.

Weed Control In Pastures : A Practical Approach For Sheep Areas, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

IN the past, chemical treatments for the control of weeds in pastures have been costly and severe on pasture, and have had to be repeated over a number of years. The method outlined in this article overcomes nearly all these disadvantages.
