A publication by UF/IFAS researchers includes information on intervals and safety when giving injections of oxytetracycline.
We’ve recently published blogs that shared information on “Best Practices” for injections of oxytetracycline from a document, “Suggested Use Pattern of Injectable Antimicrobials for Huanglongbing (HLB) Management,” created by UF/IFAS associate professors; one on timing and one on tips for injection. Lastly, we’re sharing tips for pre-harvest and re-entry intervals and safety considerations for those applying the injections. See the details below.
Injection Intervals
There are regulations in place for how often injections of oxytetracycline can be administered, and the minimum number of pre-harvest interval days between injections. This information includes:
- Bearing trees can have 1 application a year.
- Nonbearing trees can have 2 applications a year with at least 120 days between applications.
- The maximum amount of product per tree per year is 1.65 g.
- The re-entry interval (hours) is 12.
- The FRAC Group, or its classification of fungicide, is 41.
Safety for Injections of Oxytetracycline
The document shares that “Concentrated muriatic acid is highly corrosive and can cause severe skin burns and eye damage. Do not inhale fumes.”
Personal Protective Equipment should be worn when mixing and applying, including:
- Coveralls over short sleeved shirt and shorts
- Long sleeve shirt and pants
- Chemical-resistant gloves
- Shoes and socks
- Protective eyewear
- Respirator that is “at least a particulate respirator with any N,R, or P filter, NIOSH approval prefix TC-84-A.”
