Nozzle Selection for Spraying Pesticides and Fertilizer

One of the topics I will discuss at next week's Sustainable Turfgrass Management in Asia 2010 seminar is nozzle selection, spray droplet size, and water volume. Depending on the product (fertilizer? herbicide? fungicide?) being applied, its mode of action, and the reason for the application, one can choose the nozzle type that will produce the most effective spray pattern on the turf.

The Turf Diseases blog has some good posts on this topic, including photos that show the drastic differences in spray patterns between different nozzles and tips on improving disease control by proper nozzle selection.

Bermudagrass White Leaf

I recently wrote about bermudagrass white leaf, a mollicute disease seen in Asia on bermudagrass, at the Turf Diseases blog. See the bermudagrass white leaf post here. If you have this problem on your grass, it will probably go away in time as healthy plants grow over the dying chlorotic plants. For more information about ATC's investigations of bermudagrass white leaf, download the Field Day Book from 2008 at the Turf Information page of the ATC website.

The Wow Factor, Seashore Paspalum and Dollar Spot

The Wow Factor, Seashore Paspalum and Dollar Spot is now posted on the Turf Diseases Blog and may be of interest to those who manage seashore paspalum in Asia.

I will be contributing some posts to the Turf Diseases Blog on topics related turfgrass diseases in Asia. For information about all types of turfgrass diseases on warm and cool season grasses, and for advice on the management of these diseases from expert plant pathologists, you will want to read the Turf Diseases Blog this year.
