Florida Hemp, Leaf Miner Damage & IPM

Florida Hemp exhibiting leaf miner damage

 Leaf miner damage in #hemp leaves. Leaf miners are collectively a group of insects whose larvae 'mine' interior of leaves where minimal cellulose is encountered & where larvae are protected from predators. Many leaf miner species we see in our #hemp cultivation area are members of the moth, Lepidoptera, order. Leaf miner damage to hemp occurs via reduced overall plant photosynthesis & also from fungal & viral infections introduced into the plant through the leaf miner tunnels inside leaves. We use a combination of #IPM methods to control leaf miners including; bird feeding stations, yellow sticky cards with solar night lights, native plant companion plantings, lure plantings and occasional Neem or Spinosad spray applications (both organic approved). #integratedpestmanagement absolutely works best for our #FloridaHemp growing. #ArendellHillNursery #CBD #CBG #Fiber #FreshFromFlorida #Permaculture #Organic

Florida Hemp and Spittle Bugs, How Bird Feeders Help IPM

Florida Hemp & Spittle Bug Damage

We love bugs but manage Two-lined Spittle bugs, Prosapia bicincta, as they can devastate #hemp plants by injecting toxins into leaves & stems, producing white spittle looking bubbles across leaves, turning plants brown, eventually killing them. We use Neem oil spray & sticky cards at first sign of spittle bugs. Bird feeders in cultivation area are an excellent #IPM approach as birds usually eat Spittle bugs.

Assassin & minute pirate bugs &spiders devour SB nymphs too, so plant beneficial insect friendly native plants for an optimum Integrated Pest Management approach.

Earwigs (Dermaptera) and Florida Organic Hemp Cultivation

Are earwigs friend or foe in the hemp cultivation area?
Florida Organic Hemp Pest Management, Earwigs belong to the insect order Dermaptera

The answer may be both!  Earwigs can be a friend but also a foe to the organic hemp farmer and crop.

Florida Organic Hemp Pest Management, Earwigs have 'pinchers' also called 'cerci' attached to the rear of their abdomen
Earwigs are omnivores, and they are usually hungry.  From my observations across Arendell Hill Nursery, earwigs prefer aphids and other small insects.

However earwigs will also eat young, tender plant shoots, buds and leaves if there are not enough aphids, mites, insect eggs or small prey to satisfy their voracious appetites.

There are a number of earwig species and importantly, many are primarily carnivores.  The earwig preference for pest insects can be beneficial to the hemp farmer and as long as there are adequate numbers of small insects for forage. 

The key to integrating Dermaptera successfully into an organic hemp integrated pest management program lies in developing an understanding of earwig life cycle requirements.  The hemp farmer should know what environmental conditions favor earwig population growth. 

Once the hemp farmer recognizes favorable earwig growth conditions, the grower can adjust many of those factors to maintain earwig population stability, effectively avoiding population explosions while ensuring an adequate number of earwigs exist to help manage aphid issues.

Interestingly, the insect's common name 'earwig' is rumored to have been derived from a fear this bug could crawl into a sleeping person's ear at night resulting in all sorts of painful pinching.  This rumor is unfounded though and earwigs generally do not bite or pinch humans.

So are earwigs desirable as an integrated pest control partner for hemp cultivation?  I'd have to say a definitive yes.  

As with all partnerships, successful relationships require active management of interactions and the same holds true with earwigs.  An overpopulation of earwigs with not enough aphids for food will result in hemp plant bud and new growth damage as the earwigs seek out alternative food sources.

Earwig population numbers can be managed with straight forward mechanical and environmental pest control measures such as moisture control, good housekeeping and sanitary practices and regular surveillance.

The key is to have just enough earwig pest control partners.

Smart hemp cultivation site pest management can employ earwigs to hunt down and eat pesky aphids and mites.  

Employing native insects and native plants as partners in organic farming can be the safest, most effective and sustainable growing approach for Florida hemp and most all organically farmed crops.

Organic Hemp Cultivation Pest Plant Alert, Lamium amplexicaule aka Henbit

 Henbit, Lamium amplexicaule, is a purple flowered non-native groundcover with an aggressive growing habit renown for taking away native plants growing space.

Lamium amplexicaule, Henbit and Organic Hemp Cultivation


Once established, henbit is difficult to eradicate.

There are two main species of Lamium in Florida, henbit and purple deadnettle, L. purpureum.  Purple deadnettle differs from henbit visually with purple hued leaved near the plant top, or apex.  Henbit also can be usually recognized by the way it's leaves directly clasp the stem.

Although diminutive, lacy in appearance and a rather pretty groundcover, henbit might be thought of as harmless yet the opposite is true.  It is estimated by many ecological experts that almost half of all native plant species are in population decline due to loss of habitat as a result of competition from non-native species.

Lamium competes with native groundcovers for water, growing space, nutrients and importantly can be a host for hemp or other crop damaging pest insects, including a number of nematode species such as Ditylenchus spp., Heterodera spp., and Meloidogyne spp. along with a number of viruses (including Arabis mosaic virus) and fungal pathogens.

Controlling Lamium spp. in rowcrop cultivation settings can be difficult.  This weedy plant is often thought of as an annual species however it may often behave as a biennial in Florida climates.

I prefer to help establish lyre-leaf sage, Salvia lyrata or turkey tangled frog fruit, Phyla nodiflora along with a host of much better suited native groundcovers that support beneficial predatory insects, beneficial pollinators and positive biological pest management.

Personally, if I see henbit growing in the hemp cultivation areas the plant quickly becomes a candidate for pulling and mechanical eradication/composting.  Better safe than sorry when growing hemp.

Florida Organic Hemp Cultivation and Fungi Based Integrated Pest Management

 Blue oyster mushrooms, Pleurotus sp., are an important part of our Integrated Pest Management program here across Arendell Hill nursery.

Oyster mushrooms are an integral part of Organic Hemp IPM program here at Arendell Hill


Oyster mushrooms help clean stormwater and detoxify any contaminants that find their way via wind, rain or drift into the garden. 

Interestingly, many fungi are capable of absorbing complex carbon chains found in the environment and converting them into carbohydrates for their own growth.  

Mycoremediation, as the mushroom's decon process is commonly referred to, has been shown to be an effective way to support hemp cultivation area cleanliness while helping to ensure pure surface water. 

Additionally, mycobooms, which are a mixture of hay and fungal spores can be used to contain and cleanup most types of contamination spills and can be an effective pollution control management tool.

Because our cultivation areas are organically managed and free of pesticides and herbicides, the oysters in our garden are usually free of contamination and may also end up in our kitchen for dinnertime sauteing.

For decades, fungi have been successfully used in many organic-focused integrated pest management programs.  Additionally, mushrooms are fun to grow.  Cultivating oyster mushrooms as a companion species to hemp is just one, but an important part, of Arendell Hill's organic hemp integrated pest management program.

Millipedes, A Beneficial Integrated Pest Management Partner for Florida Hemp Cultivation

 Millipedes are an important #IPM partner for our #hemp cultivation plot. 


These scavengers prefer to eat moist leaves and plant litter.  

They do a marvelous cleanup job here at Arendell Hill, mulching up leaf litter and then fertilizing the soils with plenty of organic droppings.  

Millipedes help control fungal and algal explosions by keeping damp leaf debris accumulation to a minimum amount. These small arthropods are constantly foraging here.  I see them occasionally during the day but at night they are visible (with a UV light) almost everywhere across the ground.

Millipedes have 2 legs per segment side while centipedes have one.

Consider your cultivation area lucky if you are fortunate enough to have a substantial population of these beneficial arthropods.

Sow Thistle & Hemp Cultivation

 Pest plant (weed) alert! 

Sow Thistle, Sonchus sp., an invasive weed in the hemp cultivation area

Sow thistle, Sonchus sp., is native to Eurasia and Africa but can be found across Florida in yards, farms and in the woods. 

Each plant can produce up to 10,000 seeds and each seed can last many years, laying dormant until the right conditions come along. The young leaves can also be cooked as potherb greens. 

The problem with sow thistle is that the plant is so prolific and hardy with it's fat tap root that sow thistle takes away habitat from native flora (botanical adverse possession) and can crowd out hemp plants in the cultivation area.

I just mow or weed eat sow thistle down before flowers form, preventing the plants from reproducing, keeping them out of the garden. 

Often mistaken for dandelion, sow thistle is in the aster family. Both have basal rosettes yet the leaves are considerably different. Aphids are often attracted to sow thistle.

Surinam Cockroach and Organic Hemp Cultivation

 These photos are of the Surinam burrowing cockroach, Pycnoscelus surinamensis, also known as the greenhouse cockroach, an exotic pest insect originally found in south to southeast Asia.

Surinam Cockroach, a potential key pest for hemp plants

Though preferring tropical or subtropical climates, the Surinam cockroach is now recognized to thrive in temperate zones also.

Surinam cockroach is often considered an economic risk pest especially in greenhouse settings. This roach is susceptible to solar desiccation and usually ventures out at night, where in the greenhouse it has been documented to eat tender buds and plant tips.

Surinam cockroach is one of the few insects that can commonly reproduce through female cloning without male sperm. This process is referred to as parthenogenesis. Studies have shown that multiple generations of the Surinam cockroach exist in the same location without the presence of even one male.
Surinam Cockroach in the hemp garden

Because the Surinam cockroach can damage tender buds and plant tips, any roach favorable habitat such as piles of wood, trash or stacks of nursery pots should be cleaned and either disposed of or organized appropriately.

I try and encourage bird presence in areas where I've identified this pest insect as birds will prey on this insect.

Understanding the preferred habitat and taking steps to integrate predatory management approaches in the hemp cultivation plan can lead to a successful Surinam cockroach control program.

Organic Florida Hemp Cultivation, Identifying Crop Pests with UV Light

Evolution has equipped many insects with a sublime ability to camouflage themselves. 
Pest Insects may remain hidden under most light wavelengths as shown here on a greenhouse lemon balm plant.

Insects may stay hidden under daylight wavelengths too.
Evolution has equipped many insects with effective camouflage appearances


Interestingly and importantly for the grower, ultraviolet lights used at night that produce illumination in the wave range between 300nm and 400 nm can often illuminate otherwise camouflaged pest insects.

UVb light can assist in identifying the presence of crop pests


Pest reconnaissance of crops in cultivation areas including those in row plantings and in the greenhouses can be conducted at night often with successful results for insect identification efforts.

Insects, plant damage, and even chlorophyll containing algae and cyanobacteria can be identified at night by examining plant stems, leaves and flowers using UVa and UVb lights. Many insects react to UV light through florescence of phosphors in their exoskeletons. Chlorophyll on the other hand under UVb absorbs all light waves except for 'red' wavelengths which are reflected back.  Algae growing across cultivation areas can easily be identified using UVb light.

Not all insects that glow under UV light are considered pests.  Potentially beneficial organisms such as stick insects, millipedes and even anoles can be easily spotted using UVa and UVb flashlights.

My personal favorite light for night insect surveillance are lithium rechargable, well built LED units with UVb filters.

Though the grower may not spot all pest insects on their greenhouse or row crop plants, chances are any key pest infestation can be quickly identified.

Florida Hemp Cultivation Bed Preparation

 Hay arrived yesterday for spring gardens.

Hemp cultivation is made easier with a quality mulch such as organic hay.

Excellent quality organic hay is useful as a mulch in the hemp garden, usually a bit more pest free than our mulched leaves.

We do mulch and reuse our leaves too however we find hay to be a favorite for maintaining soil moisture, keeping soils less compacted and not as hot, for buffering pH and contributing to overall organic matter content.

Hay is easily to spread, lightweight and readily & sustainably available on a local basis.
