Control all three grape diseases with Pristine

08 October 2012

While Pristine also controls a range of diseases in apples, pears, stonefruit, and kiwifruit, perhaps its most suitable fit is in the grape market where the product controls all three of the major diseases at once; botrytis, powdery mildew and downy mildew. This means Pristine gives growers a powerful yet cost-effective option when planning their vineyard spray program this year.

The key to Pristine’s effectiveness in grapes is its combination of two unique active ingredients: F500®, the latest generation strobilurin, and boscalid, a new anilide molecule from BASF. These two active ingredients work in very different ways to produce a truly unique fungicide. F500 provides fast acting, long lasting disease control by blocking the energy production of the fungal cell at the Complex 3 enzyme in the fungal respiration chain. Boscalid differs however by inhibiting the Complex 2 enzyme of the respiration chain. In this manner, boscalid not only stops energy production but also stops synthesis of the amino acids and lipids that are critical for fungal growth. Another major benefit of Pristine is that because boscalid works on a different site of action than F500, there is little risk of cross-resistance to Pristine giving growers a built-in resistance management strategy.

In terms of the mode of action of Pristine, F500 is translaminar and locally systemic while boscalid is translaminar and acropetally systemic, and these effects give a level of protection into new growth as well. This dual mode of action provides growers with rapid and reliable disease control in grapes at a time when they need it most.

A large number of independent trials have shown that in grapes, Pristine matches the performance of the current market standard for the control of botrytis. Pristine was also proven to exceed the performance of the current market standards in the control of powdery mildew and downy mildew. This eliminates the need to tank mix that is common with other grape fungicides. Pristine is however able to be tank mixed with a wide range of insecticides and does not require the use of an adjuvant, thereby saving growers further time and money.

The launch of Pristine into the grape market adds to BASF’s already impressive range of proven grape products such as the fungicides Kumulus®, Polyram®, Acrobat® and Delan® as well as the herbicide Stomp® Xtra.
