In the past year the HDC's Herbaceous Perennials Technical Discussion Group has repeatedly highlighted the problem of anthracnose on lupin as a topic worthy of further research.
The group would like to improve understanding of the biology and control of the disease. Anthracnose is caused by the fungal organism Colletotrichum, leading to black spots and twisting of stems and foliage.
The Gallery series of varieties are particularly affected, leading to loss of sales.
"There has been some debate about how significant this problem is for herbaceous growers," said HDC communications manager Scott Raffle. "We need to ascertain the level of problem the industry is facing before we decide to commission research work."
"So, are your lupins bent, twisted and black? Do they resemble these images?" asked Raffle. "If lupins are an important part of your business and you have experienced these problems, HDC would like to know so that we can decide if it warrants research expenditure."
