Tackling Phytophthora in potatoes
Despite the prolonged dry period and in some parts of the country even a worrying drought situation, phytophthora has been observed in many places. That requires a comprehensive approach.
Phytophthora has been detected early in the season in various fields. Even after last week's rain (very local and large differences in the country), you still have to be careful. Irrigation is an important factor for the propagation of Phytophthora that must be taken into account.
latently present
Phytophthora is latently present (bottom) in the crop and even on the stems in many fields. The precipitation that has fallen can ensure that the infections present (and certainly infections on the stems) quickly become active again and start to spread again. It is therefore important to continue to monitor the plots closely.
Complete protection
The first yield has already been formed. In addition to any new foliage that may develop after precipitation, it is also important to protect the tubers. A nice nest of tubers has already formed on many plots, so it is important to protect both the leaves and the tubers well. It is best to opt for a complete approach to phytophthora.
The data from Euroblight, the European network of scientists and other specialists working in the field of potato blight, among others, show that Infinite is still the reference on leaf, stem and tuber phytophthora. In addition, thanks to the combination of 2 active substances (propamocarb and fluopicolide), Infinito fits perfectly in the fight against the new, more aggressive strains of phytophthora.
