Download a copy of the PX1 Alfalfa factsheet.
PX1 Alfalfa is a high performing, highly winter active variety bred from elite parent material from Australia and the USA. It demonstrates extremely fast establishment and will provide high year round forage yield, which means it can be adapted to various farming systems. PX1 has an erect plant habit and early flowering time. PX1 is perfectly suited to cut and carry operations.
- Highly winter active rating of 10
- High winter growth
- Good persistence
- Excellent pest and disease ratings
- Excellent dry matter yield
- Superior cut and carry option
- Superior establishment and reduced time to first cut compared to CUF 101 and Siriver
PEST AND DISEASE RATINGS (CROP CHARACTERISTICS,UC DAVIS, USA)
PX1 is highly resistant (HR) to spotted alfalfa aphid (Therioaphistrifolii) and blue green aphid (Acyrthosiphon kondoi). As with other alfalfa varieties, PX1 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.
PX1 Alfalfa is resistant (R) to phytophthora root rot (Phytophthora medicaginis) and anthracnose.
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.
This variety is registered under Plant Breeders Rights (PBR) in Australia. Unauthorised commercial propagation or any sale, conditioning, export, import or stocking of propagating material is
an infringement under the Plant Breeders Rights Act (1994). Any breach of this legislation will leave the grower liable for prosecution.
