The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registration for Prowl® H2O Herbicide for control of labeled weeds on transplanted field tomatoes grown in mineral soil in Canada. Prowl® H2O Herbicide was already labeled for use on a number of crops in Canada for control of several weeds.
This minor use project was submitted by Ontario as a result of minor use priorities established by growers and extension personnel.
The following is provided as an abbreviated, general outline only. Users should be making weed management decisions within a robust integrated weed management program and should consult the complete label before using Prowl® H2O Herbicide.
|Transplanted field tomatoes
||Apply once as a broadcast surface application prior to transplanting tomatoes
Prowl® H2O Herbicide is toxic to aquatic organisms and non-target terrestrial plants. Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. In field tomatoes, do not apply Prowl® H2O Herbicide more than once in two consecutive years.
Follow all other precautions, restrictions and directions for use on the Prowl® H2O Herbicide label carefully.

In recent years, Syngenta has been promoting the Defy 3D nozzle in the UK, which is a 100° flat fan, designed to run alternating 38° forward or backward along the boom. They prescribe a boom height of 50 to 75 cm, 30-40 psi, and travel speeds of 10 to 14 km/h in cereals and vegetables. Compared to a conventional flat fan, they claim that the angle and medium-coarse droplets promise less drift and improved coverage.
In 2017, Hypro and John Deere began distributing the Defy 3D in North America. Our goal was to explore coverage from the 3D in vegetable crops. We compared the nozzle’s performance to common grower practices in onion, potato and carrot in the Holland Marsh area of Ontario.
