Tomato Tuesday: Pith necrosis is caused by a bacterium Pseudomonas corrugata. Favored by cool nights, high humidity & plants exposed to excessive nitrogen. Infection can result in yellowing/wilting of portions of plants w/t dark collapsing lesions on stems/petioles #Bacteria 🧪 🌱

Rhesus Macaque (Macaca mulatta): 53cm (21in). These mammals are the most widespread non-human primates on our Planet, found in Asia. In India they can form troops of up to 200 monkeys.

The secret ingredient for the best Brussels sprouts? Frost! ❄️🥬
Cold temps trigger the plant to convert starch into sugar as a natural antifreeze. This means sweeter, nuttier sprouts with way less bitterness. If they are still in the garden, get them now! 🍽️✨

Crape myrtle bark scale (CMBS) is a pinkish insect that produces a whitish-gray waxy layer that thickens as it matures. Often 1st noticed by the presence of black sooty mold on bark, which grows on the honeydew secreted by the insects. Various methods of control available 🌱 🧪 🐞

NEMATODE MONDAY: A field of Sunn hemp in bloom is a beautiful site. It offers many benefits as a cover crop if worked into a crop rotation system. Sunn hemp suppresses weeds, slows soil erosion and reduces root-knot nematode populations 🧪 🌱

My Celestron EdgeHD 8" SCT is for capturing planetary, lunar, and deep space objects such as galaxies, star clusters, and planetary nebulae. When capturing large nebulae, I use my refractor telescope.

Corn smut (inside and out) is a disease caused by the fungus Ustilago maydis. It that forms tumor-like galls on corn plants. While it is a destructive plant disease, the immature galls are a culinary delicacy in Mexico $ other parts of the world, known as huitlacoche or Mexican truffle science 🧪 🌱

NEMATODE MONDAY Root-knot nematode (RKN) galls on tomato. Infected plants should be removed & destroyed after harvest. Roots left in soil can act as a shelter for RKN until the next season. Work soil to bring roots to surface so drying action of wind/sun can destroy the pathogen science 🧪 🌱
