GUIDE TO PEST MANAGEMENT IN FIELD TOMATO Nova Scotia Vegetable Crop Guide to Pest Management 2021 [TOM1-21] Revised March 8, 2021 by Talia Plaskett, Protected Crop Specialist, Perennia Jonathan Bent, Research Associate, Perennia IMPORTANT This publication was compiled by representatives from Perennia using information from the Pest Management Regulatory Agency of Health Canada, specific pesticide labels, previous Atlantic Provinces Vegetable Pest Guides, and manufacturer’s information. This information is continuously changing and therefore it can cease to be current and accurate. Pesticide labels are the best source of information and should always be consulted prior to using a product. The label is the best source of information on registered crop uses, rates, days to harvest, compatibility with other pesticides, toxicity, and other special information on its effective and safe use. By printing this publication, Perennia does not offer any warranty or guarantee, nor do they assume any liability for any crop loss, animal loss, health, safety, or environmental hazard caused by the use of a pesticide mentioned in this publication. WARNINGS This publication is meant to be used as a reference for possible pest control options. Where there are multiple brand names of a specific active ingredient registered in Canada, Perennia has only listed a couple for reference purposes and as such does not endorse one brand over another. If you have purchased a generic product not specifically in this guide but has your crop and pest on the label, always follow that product label. If any information in this or any other publication conflicts with the information on the label, always use the label recommendation. You are legally responsible for the safe use of pesticides you purchase. This means the safe transport and storage of these materials, the label rates used on crops, and the safe disposal of container Tomato (Field)

Perennial weeds germinating after planting. For quackgrass control,
including quackgrass apply to actively growing quackgrass when at least 4
new leaves are present. The low rate (1.67 L/ha) will
provide a minimum of one season control, while higher
rates (>1.67 L/ha) will provide longer term control. The
low rate of Roundup should be applied in 50-100 L/ha
water. If higher water volumes are used add a suitable
surfactant. Wait 72 hours before plowing under. Best
control of quackgrass is obtained when these herbicides
are applied in the fall.

Pesticide Units of Measurement
It is not recommended to convert label rates to imperial units because there is a high probability of mathematical and
rounding errors. Present day pesticides are formulated to be more effective in smaller amounts. Therefore, even small
conversion errors can lead to the use of incorrect rates (either too high or too low). Use metric – you will be glad you did!
