When using agrichemicals on your indoor tomato plants, it is important to check the compliance regulations for each activate in the product you are using. This will ensure that you aren’t sending tomatoes to market when there are still harmful residues present. It is a good idea to read the information in this booklet along with the information contained on the product label and exercise caution. If in doubt, you can send samples to be tested at a laboratory to make sure that your crop complies with the minimum residue limits (MRL). The booklet below contains MRLs and Withholding Periods (WHP) for common activates in the New Zealand market contained in insecticides and fungicides including biopesticides.

This edition has upgraded regulatory compliance information and, also how biological pest controls may be impacted by the types of agrichemicals that you may also use. There is a guide to the general principles for good management practices for biopesticides. As well as being compliant with regulations, your agrichemical choices should not be harmful to your biological controls.

An increased focus on sustainability together with consumer interest in how their produce is grown, is resulting in a significant increase in glasshouse tomato growers choosing to adopt biological pest controls as part of their integrated pest management programmes. When choosing your pest controls we would recommend referencing the charts (in the booklet) so that you fully understand possible impacts upon your biological control options.

This guide is intended to assist you with your choices in growing the most sustainable and healthy fresh tomatoes.
