Agriculture

A new agricultural adjuvant, Envirowet PCLL8 has been developed by AWT Pty Ltd. This product is completely different from any existing adjuvant on the market today and is protected by patents worldwide. It is currently under application with the Australian Pesticides and Veterinary Medicines Authority (APVMA) and registration is expected by the first quarter of 2025. 

The highlights of this adjuvant are:

Unlike any existing amphiphilic surfactant, AWT formulations are not limited by micelle formation and as such can be used at different doses and is the only adjuvant that exhibits a reverse dose effect, i.e. is more effective at lower doses. This was proven by agricultural trials conducted by Outlook Ag in the Narrabri region of NSW. This is clearly shown on the second page of the file Outlook_Ag_Wetting_agent_trial_report_August_2021.pdf where is is demonstrated that AWT formulations at 100mls per 100 litres of spray mix are less effective than at 50 mls application rate.

This dose effect is unique and does not exist with existing amphiphilic surfactants and recognized by patent authorities worldwide. This is detailed in the attached file: 

Due to no micelles being produced, a unique feature and recognized by patent authorities worldwide, the surface tension of the liquid does not change from the bulk of the liquid to the surface so there is no Marangoni Effect as occurs with all existing amphiphilic adjuvants used in agriculture today. This means there is no spray drift caused by micro droplets shearing off the surface of the spray droplet. This is without the use of any surface coating oils, the use of which leads to excess active and adjuvant use. This was confirmed by Professor Andrew Hewitt of University of Queensland a world authority on spray drift after very detailed experiments conducted at the wind tunnel facility at Gatton Qld. Please see file;  Analysis_of_Results_Wind_Tunnel_Testing_UQ_Gatton_Dec_2021_v_1.0.pdf and file Bayer_DSD_Report_Xtendimax_Tank_Mixes.pdf which is the executive summary of the full analysis.

Due to the above factors, Envirowet PCLL8 can be used at significantly lower amounts than existing amphiphilic adjuvants i.e. 20% of the current dose rate of LI700 and 40% of the current dose rate of Wetter 1000. It also requires less active than the afore mentioned adjuvants i.e., 1500mls glyphosate per 100 litres of spray mix compared to 2500mls per 100 litres of spray mix when using Wetter 1000. This was confirmed by trials conducted by the agronomists Outlook Ag. This has also been confirmed by the agronomists of Kalyx Pty Ltd who are conducting fallow trials in WA, Vic, Southern and Northern NSW and Southern Queensland as part of the APVMA registration process. Trials so far have confirmed that glyposate resistant weeds such as annual rye grass, pig weed, milk thistle, cape weed, wild radish and many others are more effectively killed using Envirowet PCLL8 with the reduced rare of glypphosate and as a result the aim is to eliminate the double knock spraying with Paraquat two weeks after the intitial Roundup spray

Envirowet PCLL8 is compatible with all water soluble herbicides insecticides and fungicides including powdered formulations such as Metsulfuron. It is also compatible with non-aqueous actives which is highly unusual for existing amphiphilic adjuvants. 

AWT Pty Ltd is seeking registration of Envirowet PCLL8 with the Australian Pesticides and Veterinary Medicines Authority (APVMA) and as such, a third party agronomist research company Kalyx is conducting large scale agricultural trials in Beverly WA, Horsham VIC, Young NSW, Narrabri NSW and Toowoomba QLD. These results have shown that Envirowet PCLL8 used at the label rate is at least as effective as Wetter 1000 and LI700.

 It is also currently being used as an adjuvant for the application of liquid foliar fertilisers by SL Tech in Northern Victoria with considerable success.
