Py Bo insecticide is registered by the APVMA for the control of aphids, ants, cabbage moth and other caterpillars, earwigs, leafhoppers, thrips and whiteflies in fruit and vegetable crops. Grapevines are considered as a fruit crop therefore, this product can be used on grapevines.

Surround does not require APVMA registration.

Due to the recent hot spell and with more high temperature events to come, the use of products such as Surround are being considered as a way of reducing leaf temperatures relative to ambient temperatures.
Surround as a protectant against sunburn and heat stress is not required to be registered by the APVMA and there is no State or Territory legislation regulating its use. The registration process is governed by Commonwealth legislation. The agricultural chemical products that require registration encompasses all herbicides, insecticides, fungicides and growth regulators. It does not include products such as Surround because they do not fit the definition of an agricultural chemical product (For more information on this definition go to Therefore, Surround can be used on grapevines despite the fact that grapevines do not appear on the label. Given the nature of the product, residues might be present at harvest, especially in the case of late season applications. We do not know if this will have any impact on the winemaking process and final wine quality. It is advised that you contact your winery or grape purchaser prior to application of this product.
