" GCTV Stored Grain: Sunflower Cooling 11 March 2014 Specialist Grain Storage agronomist Philip Burrill commenting on aeration cooling of sunflower seed in on-farm storage... Many cases we end up with no storage pests 33.64: by reducing that grain temperature... 92.899: And lastly the venting on top of the silo, we are looking to prevent obviously rain or 98.229: storms from bringing moisture into the storage and at the same time not restrict that airflow 104.2: coming out through that aeration cooling...

Principles of aerating grain for cooling and drying.. The system being used, the temperature and relative humidity of the air that is available and the grower"s or system"s ability to select the right air for the targeted grain temperature and moisture content will determine the result... To cool grain, relatively low flow-rates of air at around two litres per second per tonne (L/s/t) are pushed up through the grain stack...

3) It is widely accepted that fungicide applications are generally most effective when applied with small-droplet technology, but such applications are also associated with the highest risk of spray drift... The project is about optimizing pesticide spray applications by: identifying spray technologies and spray settings with low risk of spray drift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides and minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacy against target pests... A key nozzle technology on which we will focus is air-inducted nozzles and we will screen several popular ones first in the wind tunnel to select those that produce good control of droplet size with at least 20% air inclusions by volume...

Of SurfACe TemPerATure SPrAy OPerATiOnS in cooling night conditions airborne pesticides can concentrate near the surface and unpredictable winds can move droplets away from the target... During surface temperature inversions, air near the ground lacks turbulence... SOurCe GrAeme TePPer under a surface temperature inversion: air movement is much less turbulent so the air does not mix in the same way as during the day; airborne droplets can remain concentrated in the inversion layer for long periods of time; the direction and distance pesticides movement is very hard to predict; the movement of airborne droplets will vary depending on the landscape; and droplets or their remnants can move in different ways (figure 3)...
