PX2 is a high performing, highly winter active variety bred from elite parent material from Australia and the USA. Once established it will persist well from year to year and provide superior all year round forage yield which means it can be adapted to grazing/hay cut farming systems.
- Highly winter active rating of 10
- Excellent pest and disease ratings
- Excellent recovery after cutting
- Good dry matter yield
- Suitable for short term grazing
- Well adapted to cut and carry operations
PX2 has performed well in various trials thus far. Ongoing work is being conducted to assess its long-term performance.
It is important that alfalfa seedlings are given adequate time to establish prior to the first cut or grazing. Failure to do so can result in reduced plant numbers and hence plant density and the quality of the overall stand reduces. The first cut/graze should occur when the plants have an established root system and height around 5-10 cm. This may take 6-8 weeks depending on growing conditions. After the initial cut/graze it is important that the stand be given adequate time to regrow before going through the process again. This is normally around 4-6 weeks, care should be taken to avoid over stocking.
Pest and disease ratings (crop characteristics, UC Davis, USA)
PX2 is highly resistant (HR) to spotted alfalfa aphid (Therioaphistrifolii) and blue green aphid (Acyrthosiphon kondoi). As with other alfalfa varieties, PX2 is susceptible to damage from red legged earth mite (Halotydens destructor) and control measures need to take place prior to seeding or soon after germination. AgriCote seed will aid establishment in these circumstances.
PX2 is resistant (R) to phytophthora root rot (Phytophthora medicaginis) and anthracnose.
