Asparagus: management of phytophthora rot

In an inoculated field trial, Phytophthora sp. had a deleterious effect on crop establishment over two seasons. The pathogen was most effectively controlled using a soil drench of SL567A (0.65 L/ha) applied to re-filled gulleys immediately after crown planting.

An inoculated seedling bioassay confirmed that SL567A was the most effective fungicide (out of eight tested) for control of phytophthora rot on asparagus.
