Peaches Pest & Disease Programs — Biological Inputs That Fit Your Spray Window
Natural program for peaches and nectarines — brown rot through to the packhouse, leaf curl in spring, the fruit moth and borer complex, and the colour and sugar the fruit is graded on.
Growing peaches with Vegalab
Brown rot is the disease that decides whether a peach crop arrives, and it arrives late — at ripening and in transit, when a conventional pre-harvest interval is at its most awkward. Around it sit peach leaf curl in spring, bacterial shot hole, powdery mildew, and an insect complex of oriental fruit moth, peach fruit moth and clearwing and peach tree borers.
Zero pre-harvest interval is worth more on peaches than on almost any other crop Vegalab serves, because the highest-pressure window and the harvest window are the same window. Spore Control covers brown rot and the fungal complex right up to picking, Mildew Control rotates against powdery mildew, and Larva Control targets the fruit moth and borer complex. On the quality side, Color Boost and Brix Boost support fruit colour and sugar, and Calcium Boost supports firmness and resistance to cracking. Rates follow the registered label.

Frequently asked questions
What controls brown rot in peaches naturally?
Spore Control is a thyme-oil fungicide applied preventatively against brown rot. Because it carries zero pre-harvest interval and zero re-entry, it can be applied through the ripening window when brown rot pressure is highest.
Can I spray close to peach harvest?
Yes. All Vegalab crop protection products carry 0 PHI and 0 REI where registered, so applications are not constrained by a harvest cut-off. Always follow the applicable label.
How do I improve peach colour and sugar?
Color Boost supports fruit colour development and Brix Boost supports sugar accumulation and eating quality. Both are nutritional inputs applied ahead of harvest.
