We are a month in to the new year and I just wanted to remind everyone that if you have not already done so, it is time to start thinking about a delayed-dormant application of horticultural oil for scale insect management. The above 50\u00b0F weather makes for a lovely day, but the scale insects enjoy it too, becoming developmentally active above 51\u00b0F. That means it is a good time to nip these guys in the bud.<\/p>\n\n\n\n

For delayed dormant timing, apply dormant horticultural oil at a rate of 0.75-1.5% oil to water. It is recommended to apply the oil:water mixture at high gallonage in order to maximize coverage. As you have probably heard me say over and over again, if you are applying the delayed-dormant application to pre-pruned trees<\/strong>, then it is important to aim for 150-200 gal\/acre<\/strong> to get effective coverage, especially in areas with a history of scale pressure. If the trees have already been pruned, <\/span>then lowering the rate down to 100 gal\/acre<\/strong> seems to be effective. <\/p>\n\n\n\n

Additionally, combining an insect grower regulator, such as Centaur<\/em> or Esteem<\/em> with the oil can enhance the control of the scale. Similarly, combining Venerate<\/em> with the delayed-dormant oil application has also shown to significantly suppress scale numbers compared to oil alone. <\/p>\n\n\n\n

Alternatively, incorporating chlorpyrifos<\/em> with the oil application provide suppression of scale insects as well as lesser peachtree borer when applied at bud swell.<\/p>\n\n\n\n

For more information, please see the updated peach management guides<\/a><\/p>\n\n\n\n

Note, do not apply oil sprays within 2 weeks of (before or after) making a spray that contains sulfur.<\/em><\/p>\n\n\n\n

Speaking of the management guides, the 2021 Southeastern Peach, Nectarine, and Plum Pest Management and Culture Guides have been printed and will hopefully be available soon!<\/p>\n\n\n\n
