Pecan trees have long been a garden staple across much of the southern United States. While many growers plant these trees as a way to expand their gardens and begin harvesting various types of nuts at home, mature pecan trees are able to withstand even the harshest conditions. Though hardy, not all pecan trees are created equal, as many varieties demonstrate differing degrees of stressors. Maintaining healthy pecan trees is the key to years of successful nut harvests.
One of the most common factors of poor nut production in pecan trees is the result of stressed trees. Pecan trees which become stressed are much more susceptible to many types of fungal disease, as well as increased insect pressure. These stressors not only impact the growth of the tree, but may also cause the quantity and quality of the pecan harvest to suffer. Events such as cold temperatures, high humidity, and even drought are all responsible for the potential loss of pecan harvests. Pecan nematospora is another issue.
What is Nematospora of Pecans?
While many fungal infections may affect the growth of the tree, others such as pecan kernel discoloration will directly impact the quality of the pecan kernels. This fungal infection is caused by the fungal pathogen called nematospora. Most often, the fungus in pecan trees is caused by the damage done by stink bugs.
The most obvious sign of this disease occurs at harvest time. Infected pecan kernels will show distinct blotches of darkening and, in some cases, completely brown pecan kernels. The darkened color most often varies greatly throughout the harvest.
Controlling Nematospora of Pecans
While pecan nemotaspora is difficult to recognize and diagnose throughout the growing season, there are some steps in which gardeners are able to take to help reduce the chances of infection. Above all, proper home orchard maintenance is key. This includes routine sanitation and removal dead or diseased plant materials.
The removal of these materials will discourage the presence of stink bugs, as well as remove any previously infected plant matter. Adherence to a frequent irrigation program will also help to prevent plant stress and result in overall healthier pecan trees.

Two words: pecan pie. Got your attention? If you’ve got the space and time, you should consider growing pecans, and not only to make dessert.
They can also be used in savory dishes or to make some extra cash. On top of that, they’re also a beautiful landscape tree that provides wonderful shade on a sunny day.
Pecans are native to the southern US where they’re a quintessential dessert food. Pecan pie, pralines, ice cream, maple pecan tarts are a few of my favorites. Memories of pecan based foods make my mouth water.
Kaj je Nematospora Pecans?
Medtem ko številne glivične okužbe lahko vplivajo na rast drevesa, bodo druge, na primer razbarvanje pecanovih jedrc, neposredno vplivale na kakovost pecanovih jedrc. To glivično okužbo povzroča glivični patogen, imenovan nematospora. Najpogosteje glive na drevesih orehov povzročajo škode, ki jih povzročajo smrdljive žuželke.
Najbolj očiten znak te bolezni se pojavi v času žetve. Okužena pecanova jedrca bodo pokazala izrazite madeže potemnelih in v nekaterih primerih popolnoma rjava pecanova jedrca. Zatemnjena barva se najpogosteje močno razlikuje med letino.
Do eat: Hazelnuts
If you love nothing more than hazelnut-filled cookies, you're in luck. They're incredibly good for you, as they're filled with things like vitamins A and B. Hazelnuts have a healthy dose of dietary fiber, and they also help raise good cholesterol while lowering the bad. You're not just doing yourself a favor when you help yourself to a handful, you're helping the environment, too.
Hazelnuts are a great example of sustainable agriculture. Not only do they require little water and minimal upkeep, but they can thrive in harsh soils where other plants would fail. They're drought-resistant, can survive harsh weather conditions, have a high yield per plant, and help prevent soil erosion. They also have massive root system, and they remove a huge amount of carbon from the atmosphere. It's a good thing they're so tasty, and even if you already have your favorite ways to use them, you'll still have to try this dairy-free dark chocolate and hazelnut spread from Beach Body on Demand, and this chocolate hazelnut fudge from Texanerin. Being environmentally friendly never tasted so good!
Chemical Pest Treatment
Pesticides aren't typically recommended for controlling mild to moderate stink bug and leaffooted bug populations, but permethrin-based sprays can help treat severe infestations. Carefully read and follow the directions on the manufacturer's label. One permethrin-based product recommends combining 2 fluid ounces of product with 1 gallon of water in a handheld garden sprayer. Apply the solution to the pecan foliage until it glistens with moisture, making sure you thoroughly cover the undersides of leaves. Start spraying when insects appear and reapply as needed, but don't spray your pecan tree more than five times in a single growing season. You can use a permethrin spray up to seven days before harvesting pecan nuts.
