Efficient Spraying to Meet Environmental Demands "learning to spray with coarser sprays" Spraying is about placing the correct dose of chemical at the right place at the right time... Without pesticides the world would find feeding itself a monumental challenge, but this does not mean that the community at large embraces the idea of managing pests with chemicals... As farmers today, I believe we are making some decisions that may lead to increased drift risk...

The capacity of the plant to take up potassium is not directly related to potassium in solution... Spraying is best done when there is some wind, and when the operator can be sure that wind direction has stabilised... Driftability of amine formulations The 2,4- D products Surpass and Amicide 625 which were used in the trial are considered to be nonvolatile any drift that is associated with these products will be droplet drift not vapour drift...

Cameron Tonkin & Giles Butler (NSW Agriculture) 9:45 AM How the crop produces grain -getting the basics right.. Ground cover is estimated by looking at a crop in several places around a paddock at an angle of 45 through the hole created by putting the tip of your index finger and thumb together and estimating the percentage of the hole covered by crop, not soil... Plant height measured on 6/2/01 after each crop was: after wheat: 22 cm after canola: 18 cm after mustard: 16 cm..

The methods, once developed, will make a very great improvement in the speed of development of new varieties and the value of the varieties to growers... Using advanced biotech and rigorous evaluation we can reduce the release time for cultivars to 5-7 years for wheat and 7-8 for barley... Unstable air is not likely to lead to high off target spray drift concentrations measured at ground level...

The methods, once developed, will make a very great improvement in the speed of development of new varieties and the value of the varieties to growers... Enzyme technologies There is renewed interest in using enzymes in primary and secondary processing of grains, as an alternative to solvents, some of which (e.g. hexane) are becoming almost prohibitively expensive...
