2019 Hemp Intern:

CCE Orange will be hosting a Cornell Student Intern this summer to do hemp crop pest evaluations as well as collect as much data as possible on production practices and costs for developing academic budgets.  This intern will be like a field scout (or greenhouse) and do scouting on a certain number of fields/locations each week.  There may be a bi-weekly schedule to visit the same fields/locations every other fields/locations to increase the number of fields she can get to – but all numbers depend on interest.   So….who is interested? (contact Maire at mru2@cornell.edu )   Likely, there will be nominal fee to offset mileage costs as she will be travelling through several counties.  Expressing interest in not binding.  Also, if you do not “sign-up” for the scout, emergency visits will still be possible if you have an urgent matter with your hemp crop.

Crop Production Notes from Cornell Faculty:

Weed management for Hemp 2019

There are no selective herbicides yet registered specifically for use in hemp. Weed control in hemp might best achieved with a combination of different cultural. One method to try might be to start with the stale seed bed technique. This practice allows weed seedlings to emerge for several days to 4 weeks after the field has been finally fitted for seeding. After significant weed emergence and before they are too large, the weed cover is removed. The method of removal is somewhat limited for hemp. The postemergence herbicide SUPPRESS is labeled for this type of use generally for all food and fiber crops. SUPPRESS is OMRI approved as an organic herbicide. However. It will only work well on small broadleaf weeds and its cost may be prohibitive. Propane flaming or even light surface cultivation are other possible means of removed the emerged weed cover. This operation should then be followed with direct seeding of the crop without further soil disturbance. Even in the best of circumstances this will not provide 100% weed control, but it can reduce the initial weed growth so that a vigorous crop can outpace the weeds. (A. Senesac)

Disease management for Hemp 2019

Sil-MATRIX (EPA Reg. No. 82100-1) is a fungicide/miticide/insecticide that contains 29% potassium silicate, the active ingredient.  It is labeled for use on numerous crops including industrial hemp.  It is described as a broad spectrum, preventative fungicide.  Powdery mildew is the only labeled disease for vegetables, fruits, nuts, vine crops, agronomic crops, and ornamentals.  Labeled insect pests are aphids, spider mites, and whiteflies.  It is approved for use in organic production (OMRI listed).  Based on my experience testing organic fungicides for powdery mildew in vegetable crops, I would expect Sil-MATRIX to provide moderately good control of this disease in hemp when applied on a regular (weekly) basis starting before or at start of disease development, especially if this powdery mildew occurs predominantly on the upper leaf surface or it is possible to achieve good spray coverage on the underside of leaves. (M. McGrath)

Alternative Pest Management:

Also consider products from here as some are not pesticides but fertilizers or soil inoculants that can be used to improve plant health so they can better fend off pests.
