Spraying milk for red thread
I am planning to spray my lawn with milk to prevent red thread and have acouple of questions to anyone that has done it with success. How often does it need to be done? Does the fungicidal properties of the milk work on the surface of the grass, in the soil, or is it systemic? If there is an outbreak,can the diluted milk be applied diectly to an infected area such that it would prevent spreading the spores.
Lastly is there anything that can be added to the hose end sprayer that will make the application stick or maybe somewhat rainproof?
Thanks in advance
