Weed Control In Cereals And Pastures Including Declared Plants., J. Peirce, B. J. Rayner Jan 1990

Weed Control In Cereals And Pastures Including Declared Plants., J. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 90C49

Grass and broad leaved weed control in direct sown crops.

Location: Chapman Valley Research Station.

The low rate of sprayseed with diuron was not as effective on the grasses. It may indicate some antagonism within the mix as the same rate of sprayseed with metribuzin did not cause any drop in grass control. The addition of 2, 4-D amine may have boosted the mixes activity on capeweed as the sprayseed metribuzin mix was not very good on capeweed.

Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd Jan 1989

Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd

Experimental Summaries - Plant Research

Trials : 88BY26, 88PE34, 88MD35

Control of Rhizoctonia solani infection of potato stems and daughter tubers was demonstrated by preplanting applications of tolclofos-methyl (RIZOLEX TM) to either cut or round seed tubers. Yield of tubers from cut seed treated with Rizolex was increased over that of cut seed cured before planting bu not when seed was cut and planted the same day. Crops grown from round seed treated with Rizolex yielded higher than from untreated round seed.

Surface sterilization of seed tubers with Sodium hypochlorite was effective in reducing stem damage but not in reducing daughter tuber sclerotes. This indicates …

Trial 88EB26

While this site had a low population of weeds no yield increases were apparent. Few variety differeces were apparent at this site, though Hoegrass + Glean reduced yield of Crabook significantly.

Trial 88EC27

Few crop effects were experienced at this site. The major effect was due to variable fertility in replicates 3 and 4 and this resulted in the somewhat uyp and down nature for the Glean, Logran and hoegrass results.

Trial 88SC32

This site had a major problem with soil acidity and only triticale and oats grew satisfactorily. Barley was strongly influenced by the acidity and many …

Lupin Variety Tolerance To Herbicides, D Bowran, R Watson

Experimental Summaries - Plant Research

Trial 88EC31

This site received a basal treatment of 1.5 L of simazine/ha prior to seeding. Due to a heavy stubble load lupin seed was dropped onto the surface and lightly incorporated.

High rates of Simazine were better tolerated by Gungurru 75A/260 and CE2/435. The highest rate of Brodal reduced yields in all varieties except Gungurru.

Trial 88EB27

This site was severely infested with aphids and bean mosaic virus such that the varieties Illyarrie and Danja had up to 60% plant death by anthesis. Other varieties were affected but to a lesser extent.

Trial No. 88WH58

Doublegee demography in cereal crops.

Objective: To measure reproductive output in relation to times of emergence and herbicide application.

Trial No. 88WH10

Growth of doublegee under summer irrigation.

Objectives: A major impediment to achieving biological control of any annual weed in the wheat belt is that the bicontrol agent must have a means of aestivation. Since the only insect to have been introduced to Australia for a the control of doublegee does not aestivate, it was thought that populations could be able to oversummer in irrigated doublegee standards. The aim of this study was to assess the …
