Allium Vineale
Allium Vineale is a cool-season perennial with slender, hollow cylindrical leaves. It is often confused with wild onions. The easiest way to tell the difference is that there is a v-shaped channel in the leaves of the hyacinth. Its presence indicates very low calcium, very high potassium, very high magnesium, high sodium, very high chlorine, and a low bacterial count.
Annual Bluegrass
Poa Annua, or Annual Bluegrass, is a small tufted to clumped winter annual. It has light green to whitish spikelets in dense to open flower clusters. Its presence indicates low calcium, very high potassium, very high magnesium, very high sodium, high chlorine, low bacterial count, and poor drainage.
Aphids
Aphids, also called plant lice, are small (up to ¼ inch), soft bodied insects that will infest most garden plants. Aphids can cause severe distortion and stunting on a plant.
Armyworm
The armyworm is a sporadic, but occasionally severe pest of turfgrass. They feed as a group, devouring the grass in roughly circular patches before moving on to the next available food. Every bit of green leaf and stem may be stripped by the horde of larvae.
Bagworm
Bagworms are the larvae of moths. The characteristic brown bags are often seen attached to twigs. The bags are up to two inches long and composed of interwoven bits of dead foliage, twigs and silk. At first it drags the bag around as it feeds on leaves, enlarging the bag as it grows. By late August, the caterpillar finishes its feeding and attaches the bag to a twig. In severe infestations, the entire plant is defoliated and there are bags hanging on many of the twigs.
Billbug
Billbugs are small weevils, 1/3 inch long, with long, downward-pointing snouts and elbowed and clubbed antennae. Often seen walking on paved areas, they first feed on the inside of turfgrass stems and crowns, then move to feed on roots. The affected area appears brown, thin and dead in small irregular spots.
Bittercress
Bittercress leaves consist of two to four pairs of round leaflets arranged alternately along the stem, up to 12 in. high. Small white flowers occur in clusters at the end of stems. It is often found in wet, disturbed areas such as landscape beds, containers or poorly drained turf.
Blackmedic
Blackmedic is a low-trailing summer annual that can act as a perennial in some conditions. It is very common in lawns stressed from compaction, heat and drought.
Blight
Blight refers to a specific symptom affecting plants in response to infection by a pathogenic organism. It is simply a rapid and complete chlorosis, browning, and then death of plant tissues such as leaves, branches, twigs or floral organs.
Broomsedge
Broomsedge is a perennial weed that can be distinguished from other grasses by the flattened leaf sheaths which have obvious leaf hairs. Leaves with folded vernation arise from a basal crown. Mowing at the recommended height for the selected turfgrass and removing clippings when seed heads of grassy weeds are present help control these weedy grasses from becoming established in turf.
Brown Patch
Brown Patch initially appears as circular-shaped patches with a diameter of one to five inches. The patches develop quickly up to two feet in diameter and fade to a light brown color. It typically starts to appear during a period of high temperature and high humidity in early summer, and may continue to develop until very late summer.
Buckhorn Plantain
Buckhorn Plantain is a perennial with a distinctive rosette of egg-shaped leaves. Its presence indicates very low calcium, very high potassium, very high magnesium, high sodium, high chlorine, and low humus.
Buckshot
Buckshot is a fungal disease which leaves telltale signs of illness on leaves through unsightly leaf spots, holes, rusts and mildews.
Buttonweed
Buttonweed is a troublesome broadleaf weed in turfgrass throughout the South. This deep-rooted perennial with prostrate or spreading branches usually proliferates in moist to wet areas. The leaves are slightly thickened with green on the upper surface, light green on the lower surface and often have a mottles yellow mosaic appearance. Overwatering or excessive rainfall during growing periods may predispose the site to the invasion of buttonweed.
