The Department of the Environment of Australia believes that the proposed use poses a low risk to mammals and birds, but a high risk to bees and other potentially non target land insects. The damage to earthworms is considered to be very low.


According to the best agricultural guidelines, namely the new Handbook of Best Management Practices for Cotton Farmers or the Handbook of Safe Spraying Operations: Pilots and Operators, the harm to fish and water fleas and other aquatic invertebrates (the most sensitive organisms) when sprayed by air is considered to be very low.


The boom sprayer is less harmful to the spray drift of aquatic invertebrates near the spraying operation. Based on the aquatic organisms tested, runoff from the treatment area is not considered hazardous to aquatic invertebrates.


In conclusion, the Australian Department of the Environment can support the use of the proposed Metasystox R system insecticide (250 g/L, oxydesone methyl).

 

Methoxymethadone is recommended to control aphids of rape vegetable crops, cotton (NSW, QLD, NT and WA only) and lupins (NSW, VIC, SA and WA only) through ground equipment or air use. For details on the usage mode, please refer to the usage instruction table on the draft product label (pages 31 - 34).


The Metasystox R system will provide 1 liter, 5 liter, 10 liter, 20 liter and 200 liter containers.


Different crops have different utilization rates; Brassica vegetable crops 1.1 l/ha; Cotton 300ml/ha; Lupin is 300 ml or 560 ml per hectare, depending on the aphids under control. The maximum number of applications for each season is 3 brassica vegetables, 2 cotton and 1 lupin.


The data provided by Bayer Australia Limited supports the statement that Metasystox R system insecticide can effectively control aphids in rape vegetable crops, cotton and lupine beans. These data were collected from a series of repeated and unreplicated experiments.

 

No phytotoxicity of Metasystox R system insecticides to Brassica vegetable crops, cotton or lupin was observed in all tests.


In terms of insecticide resistance management, poly (insecticide R) belongs to Class 1B insecticide. In any insect population, through normal genetic variability, there may be some naturally occurring insect biotypes that are resistant to Zombidium R and other 1B insecticides. If measystox R and other Class 1B insecticides are reused, drug resistant individuals can eventually dominate the insect population. The effectiveness of Metasystox R on drug resistant individuals may be significantly reduced. As it is difficult to detect the occurrence of drug resistant individuals before use, Bayer Australia Ltd. will not bear any losses that may be caused by the failure of Metasystox R to control drug resistant insects. Metasystox R may be affected by specific drug resistance management strategies. For more information, please contact your local supplier, Bayer representative or agronomist from the local agricultural department.


Compatibility


PAM R is compatible with the most commonly used insecticides and fungicides, including Antrifol (R), Double Mosquito rex (R) 500 SL, Helothion (R) and Tokuthion. The compatibility given is based on worldwide experience and is considered correct. However, since changes in climate conditions will change the sensitivity of plants to spray mixtures, we are not responsible for the behavior of such mixtures.


Store in an original closed container in a well ventilated area, as cool as possible. Do not store in direct sunlight for a long time. Flush the container with three times or (preferably) more pressure before disposal. Add rinsing agent to the spray tank. Do not dispose of undiluted chemicals on site. Break, crush, puncture and bury empty containers in the local government's landfill. If not, the container shall be buried in a treatment pit below 500 mm, specially marked and set for this purpose, and the waterway, vegetation and roots shall be removed. Empty containers and products shall not be burned.
