Dormant oil sprays are a valuable tool for fruit tree health and pest management in Nevada. Done at the right time and with the correct technique, dormant oil reduces overwintering eggs and scales, suppresses mites, and lowers early-season pest pressure so trees get a healthier start into the growing season. Done at the wrong time […]
Beneficial nematodes are microscopic roundworms used as biological control agents against a wide range of soil-dwelling insect pests. In Nevada, where soils range from alkaline desert sands to irrigated urban and agricultural loams, selecting the appropriate nematode species and applying them correctly can reduce pest pressure while minimizing chemical pesticide use. This article explains the […]
Finding an unfamiliar insect, spider, beetle, or other pest in your Nevada garden can be unsettling. Nevada’s varied climates–from high desert around Reno to the hotter low-elevation valleys near Las Vegas–create conditions for different pest pressures. The right response depends on accurate identification, assessing risk, and selecting measured control tactics that protect plants, pollinators, and […]
Nevada presents special challenges for gardeners trying to protect seedlings from snails and slugs.

This article provides a thorough, practical […]
Cleaning and sanitizing tools is one of the simplest, most effective ways to reduce disease spread in home and community gardens. In Nevada’s unique climate — arid, often dusty, and with water as a limited resource — careful sanitation protects plants and helps you avoid costly losses from fungal, bacterial, and viral infections. This guide […]
Nevada is defined by its rugged ranges, wide basins, sparse vegetation, and a climate range that stretches from the high Great Basin to the Mojave Desert. Encouraging native predators in these landscapes is not only compatible with conservation goals, it is a practical strategy to improve ecosystem function, reduce pest pressure, and increase biological resilience. […]
Sudden dieback in a fruit tree is alarming. In Nevada’s high desert and irrigated valleys, trees are subject to a unique mix of stresses: extreme heat, low humidity, alkaline or saline soils, fluctuating irrigation, insect pressures, and occasional severe winter or spring cold events. Quick, systematic action can save the tree or limit the spread […]

Overview: why diagnosing viral symptoms matters in Nevada Tomato viruses can rapidly reduce yield, ruin fruit quality, and complicate management decisions for both backyard gardeners and commercial producers in Nevada. Accurate diagnosis is the first step to effective control: it determines whether a problem is contagious and vector-borne or instead the result of nutrition, water […]
Drought in Nevada is not just a shortage of water; it is a cascade of biological and ecological changes that alters how trees function, defend themselves, and interact with insects and pathogens. Over the past decades, extended droughts and higher temperatures have exacerbated tree mortality and pest outbreaks across Nevada’s urban and wildland landscapes. This […]
Gardening in Nevada offers both advantages and challenges. The dry climate and high summer temperatures can reduce some disease pressure, but irrigation practices, microclimates, and cooler mountain locations still create conditions favorable for fungal and oomycete pathogens. This article presents practical, proven strategies for reducing fungal problems in Nevada vegetable gardens, with step-by-step actions you […]
Early detection of bark beetle activity is the single most important factor in preventing widespread loss of shade trees in Nevada. Bark beetles are small but destructive insects that often exploit trees weakened by drought, heat, soil compaction, or injury. This article explains which beetles are most relevant in Nevada, the subtle early signs to […]
Nevada orchards occupy a range of climates: low-elevation irrigated valleys, high-desert benches, and mountain foothills. The state is predominantly arid, but localized irrigation, early spring moisture, river corridors, and late snowmelt can create brief but critical windows for fungal infection. Preventive fungicide timing in Nevada must therefore be guided by tree phenology, local weather patterns, […]
Invasive weeds are more than an aesthetic or agricultural nuisance in Nevada. Many nonnative plants create microhabitats that shelter and sustain insect, disease, and vertebrate pests. Those pests then threaten native vegetation, crops, livestock, infrastructure, and human and animal health. This article profiles the most important invasive weeds found across Nevada, explains the kinds of […]
Early detection of pest hotspots in Nevada vegetable beds saves plants, water, time, and money. Nevada presents a range of growing conditions — from high desert cold nights to hot, arid southern valleys and irrigated mountain foothills — and each microclimate affects pest pressure and scouting priorities.
