Fall is officially here! 🍁 It's time to prepare for garden and landscape pest problems that could come with the changing season. UC IPM's Seasonal Landscape IPM Checklist is a monthly guide to help you avoid common pests of landscape plants: ipm.ucanr.edu/home-and-lan...

#garden #pestmanagement

A text box over a background image of fallen leaves in hues of orange, yellow and brown. The text says: IPM Tips for Fall. Clean up fallen fruit and leaves to avoid harboring pests. Keep mosquitoes away by removing clutter that could collect standing water before the rainy season. Prevent root rot by not overwatering plants and improving drainage. Create a fire safe landscape by removing weeds and dead plants. Thin out thick vegetation and prune dead material from trees and shrubs. Apply a preventative spray for peach leaf curl once or more during late fall through bud break if leaf curl has been a problem on nectarine or peach.

Are tiny maggots coming out of your homegrown berries? They might be spotted wing drosophila. These flies can ruin your harvest by infesting fruit before it ripens. Learn how to protect your berry patch from this pest on our blog ucanr.edu/blog/pests-u...

A close-up image of blackberries in the background, and three images in the foreground: an insect-damaged cherry with a hole in it, a cut-open cherry with a tiny, white maggot in it, and a small, pale brown fly with red eyes and a dark spot on the tip of each wing. The text says “Maggots in your berries? They might be spotted wing drosophila. Damaged fruit: this fly infests soft-skinned fruit like cherries, strawberries, and blackberries. Look for prematurely rotting fruit and a small hole where eggs were laid. Maggots: Check for immature spotted wing drosophila: tiny, white worm-like maggots that develop inside fruit. Spots on wings: Adults are light brown, have red eyes, and are less than 1/8 inch long. Look for a black spot on the tip of each wing.”

Plague is a rare but serious disease that can be transmitted to humans and pets, including cats and dogs. Plague is usually transmitted through the bites of fleas that have fed on infected wild rodents like squirrels and chipmunks. Symptoms include fever, nausea, weakness, and swollen lymph nodes. Do not feed wild rodents, and keep pets away from them. If you become sick after being in an area where plague is known to occur, consult a doctor and let them know you may have been exposed to plague. If your cat or dog becomes sick after being in contact with rodents, consult a veterinarian."

Text over photo of white, fluffy pampasgrass stalks: Keep Invasive Plants Out! Use plants native to your area for landscaping. Become familiar with which ornamental plants are invasive and their non-invasive alternatives. Clean off shoes, socks, and tools if they get covered in plant seeds while hiking, traveling or gardening. When traveling, don’t bring plant material back to California. Remove invasive plants in your yard. Bag and dispose of them in the trash. Invasive weed seeds can survive in compost. Join a local habitat restoration effort to remove invasive plants in natural areas.

State & federal agencies monitor frequently for new invasive pests, but the public is often the first to find them. Here are 3 invasive species not established in California that you can look out for. 🪲👀 Learn more at ucanr.edu/blog/pests-u....

#CISAW #gardening #invasive #California

Text with photos of insects: Look Out for Invasive Insects. Japanese beetle: A pest of roses, grapes, and fruit trees. Adults skeletonize leaves and larvae feed on lawns. They can be moved to new areas on infested plants or soil. Emerald ash borer: A significant pest of ash trees. Eggs are laid on branches and trunks. Larvae bore into trees creating galleries that weaken the tree. Causes D-shaped exit holes in bark. Frequently moved on firewood. Spotted lanternfly: A pest of grapes, fruit trees, and hardwood trees. Egg masses are laid on firewood, cars, and other hard surfaces making them easily moved to new areas.
