Many species of Phytophthora are plant pathogens of considerable economic importance. Phytophthora infestans was the infective agent of the potato blight that caused the Great Irish Famine (1845-1849), and still remains the most destructive pathogen of solanaceous crops, such as tomato and prevalently potato. The soya bean root and stem rot agent, Phytophthora sojae, has also caused longstanding problems for the agricultural industry. ## MIXING To ensure even mixing, half fill the spray tank with clean water and add the required amount of product. Agitate thoroughly then add the remainder of the water. Agitate thoroughly while carrying out spray operations. Reseal part-used containers immediately after use. ## COMPATIBILITY NutriFUSION PHOSFUSION is compatible with a wide range of agricultural products. If unsure of tank mixes always conduct a jar test and test spray a small area of the target crop. For the latest results of compatibility please contact the retailer. ## NOTE * All suggested application rates are for typical Australian conditions, and should be used as guidelines only. Individual conditions such as climate, water quantity, soil type and application practices may differ, necessitating corrections to ensure optimum results. Increase minimum dilution rate by 1:50 - 1:100 in hot weather for foliar feed. * Ideally brix or leaf tests should be conducted on a regular basis to determine plant nutrient levels at each growth stage. It is highly recommended to conduct soil tests at least once a year. * Avoid application under extreme weather conditions, temperature over 28°C, high humidity, frost or rain. Apply using a minimum of at least the labelled dilution rate to avoid potential leaf burn. * It is advisable when applying for the first time or in conjunction with other products, to spray an initial small test area for observation before general application. © 2020 Loveland Agri Products.
