Trial T5, shown in Figure 2(b), included dynamic spraying along alley 5; a mixture of spray drift
and field dust was generated.
The data from spray tests were collected and analysis of variance (ANOVA) on spray drift
was carried out, using a mathematical model for a completely randomized design.
. Because Colombia allows aerial eradication of drug crops, there have been complaints about food crops, and even alternative development sites being sprayed.
Hadar (1991) reported that air-assisted spraying is an effective method of improving spray penetration and reducing spray drift
. However, air volume and speed must be uniform along the boom.
She continues, "If these pesticides are capable of killing fish in minute quantities, just what do people think is happening when their children inhale toxic spray drift
or play on the grass near potato fields?
has also made available a new educational kit that allows in-depth training on tuning up sprayers, selecting proper spray nozzles, and managing spray drift
. The kit contains discussion outlines for three training sessions; instructional materials that can be used as handouts; a TeeJet Calibration calculator, a hand-held electronic computer/stopwatch with programmed calibration formulas; two instructional videotapes, samples of TeeJet spray tips and a triple nozzle assembly for demonstration; and issues of the latest catalogs from the company, which also provide information on spraying and equipment maintenance.
Old and new flower beds and borders were converted to drip irrigation, which eliminated spray drift
Ms Megirian said the GRDC Spray Water Quality Fact Sheet, available on the GRDC Spray Drift
web page, contained information about water testing, including what should be measured and how to address any issues identified through testing.
Buffer types include spray drift
buffers, field borders, riparian buffers, and vegetative filter strips.
Distance of deposition defines the spray drift
which is considered as the main source of contamination of pesticide applications in tree crops .
It also dramatically reduces spray drift
, and thus run-off, and glyphosate itself is a better alternative to MCPA because it kills plant roots.
: Impact of the requirements to protect the environment.
