Monitoring tomato plants regularly from seedling to harvest allows for early detection of abnormal conditions. Although tomato plants can be attacked by a variety of living organisms (insects, mites, pathogens, vertebrates), nonliving (abiotic) conditions can cause just as much damage. Abiotic diseases in tomato plants can arise from nutrient deficiencies, temperature extremes, abnormal lighting, chemical application, changes in water uptake, mechanical damage, genetic mutations, and more. This guide will cover most of the abiotic disorders and diseases that can affect tomatoes in Utah.

Effect Of Volatile Compounds Produced By Selected Bacterial Endophytes In Promoting Plant Growth, Asha Maheshwari, Margaret T. Mmbaga, Bandana Bhusal, Christine A. Ondzighi-Assoume
Agricultural and Environmental Sciences Faculty Research
Bacterial endophytes selected for their capability to suppress diverse fungal pathogens in vitro and in greenhouse studies have been shown to promote plant growth. The effect of volatile compounds emitted by selected bacteria on plant growth in Arabidopsis thaliana, tomato (Solanum lycopersicum), sweet pepper (Capsicum annuum), and cucumbers (Cucumis sativus) was evaluated on container-grown plants nested above bacterial cultures, with roots exposed to the volatiles without direct contact between bacterial cells and the plant roots. Significant increases in plant growth were observed in plant height, root length, leaf size, fresh weight, and chlorophyll content in all plants tested. Although diverse …

Influence Of Vermicompost Tea On Secondary Metabolites In Solanum Lycopersicum Within South Florida, Daphne K. Sugino Souffront
FIU Electronic Theses and Dissertations
Fresh Market Tomatoes provide a high revenue stream for Florida’s agricultural sector. To attain profitable yields, farmers introduce high inputs of pesticides to suppress pest invasion/damage. Heavy usage of pesticides has adverse effects on human and environmental health. A possible solution might be the incorporation of vermicompost in pest management. Typically used as a fertilizer, vermicompost has pest suppressant properties. Mechanisms influencing enhanced pest resistance are unknown. To identify such mechanisms, a study was conducted to evaluate physical and chemical changes of the BHN589 tomato plant following the addition of varying vermicompost tea treatments (T5%, T10%, and T20%) . Results …

Midwest Vegetable Trial Report For 2014, Elizabeth Maynard
Purdue Fruit and Vegetable Research Reports
This is a compilation of 30 research trial reports from seven land-grant universities in the midwestern and northeastern United States. Crops covered include Asian vegetables (Napa cabbage, pak choy or bok choi, mizuna, tatsoi, Yukina savoy, komatsuna, senposai, and Tokyo bekana) broccoli, cantaloupe, cucumber, kohlrabi, pepper, potato, pumpkin, radish, sweet corn, tomato, and watermelon. Several crops were evaluated in high tunnels or hoophouses. Most trials compared different cultivars or varieties. Four reports addressed specific growing practices: the use of hairy vetch to supply nitrogen, biochar use in a high tunnel bag culture system, effects of organic soil amendments, and scion-rootstock …

On-Farm Evaluation Of Tomato Cultivars For Disease Resistance, 2008, Elizabeth Maynard, Butch Zandstra, Dan Egel
Midwest Vegetable Trial Reports
"Bacterial spot of tomatoes (Xanthomonas campestris pv. vesicatoria) causes lesions on leaves, stems and fruit. Under conditions of hot, humid, rainy weather, defoliation can result in a loss of yield. In addition, lesions on fruit result in a direct loss of marketability. This disease is managed primarily with applications of fixed copper bactericides, crop rotations, greenhouse sanitation, and healthy seed/transplants. Even in properly managed commercial fields, however, bacterial spot can cause yield losses. Although there are no varieties with complete resistance to bacterial spot, we report here the results of an on-farm trial that indicates some varieties may have partial …

Fresh Market Tomato Cultivar Evaluation For Northern Indiana, 2005, Elizabeth T. Maynard
Purdue Fruit and Vegetable Research Reports
The Indiana Agricultural Statistics Service reported that tomatoes for fresh market sales were harvested from 1,700 acres in Indiana in 2004 and had a total value of $21 million. Tomato fields are located throughout the state. Traditional wholesale buyers look for a large, firm, round tomato that will be red when ripe. Tomato growers are interested in identifying cultivars that show resistance to common foliar diseases like early blight and bacterial spot. Eleven semideterminate large-fruited red tomato varieties were evaluated in a replicated trial at the Pinney-Purdue Agricultural Center in Wanatah, Indiana. Four indeterminate varieties reported to be resistant to …

Purdue Fruit and Vegetable Research Reports
Colorful tomato salads are a seasonal menu item for some restaurants. The many colors of tomato fruit available include orange, green, white, yellow and, of course, red. Producers growing for this market have a choice of several cultivars of each color, and sometimes several fruit shapes within a color. Many of the cultivars are open-pollinated but some hybrids are available. Prior experience at Rhoads Farm and elsewhere has shown that many open-pollinated cultivars yield poorly under Indiana conditions, making them an unprofitable crop. The trials presented in this report were established to evaluate tomato cultivars for the restaurant salad market.
Fresh Market Tomato Pruning Trial For Northern Indiana, 2001, Elizabeth Maynard
Fresh Market Tomato Pruning Trial For Northern Indiana, 2001, Elizabeth Maynard
Purdue Fruit and Vegetable Research Reports
Pruning tomatoes is known to increase average fruit size and decrease total yield. Effects on marketable yield and early yield vary among cultivars and with the degree of pruning. This trial was conducted to evaluate a range of pruning treatments on two cultivars grown in the Midwest: Mountain Spring and Florida 91. Florida 91 has a larger vine and is later-maturing than Mountain Spring. The trial was conducted at the Pinney-Purdue Agricultural Center in Wanatah, Indiana.

Purdue Fruit and Vegetable Research Reports
Fresh market tomatoes were evaluated at the Pinney-Purdue Agricultural Center in Wanatah, Indiana. Nine beefsteak types and one roma type were evaluated in a replicated trial. Plants were grown with and without pruning to evaluate pruning effects on yield and fruit quality. The main benefit of pruning is larger fruit size. For some cultivars, there might be an increase in total yield at the first harvest with pruning, as was seen to a small extent for Mt. Spring. Pruning also reduced the incidence of catfacing, especially for early cultivars. The main drawback of pruning is reduced yield. For pruning to …

Fresh Market Tomato Cultivar Evaluation For Northern Indiana, 1999, Elizabeth Maynard
Purdue Fruit and Vegetable Research Reports
Fresh market tomatoes were evaluated at the Pinney-Purdue Ag Center in Wanatah, Indiana. Fourteen cultivars were evaluated in a replicated trial, and 26 cultivars in an unreplicated observation trial. Half of the plants of each cultivar were pruned, and half were not, to evaluate pruning effects on yield and fruit quality. In the replicated trial, averaged over all cultivars,
pruning reduced yield of No. 1 fruit by 41%, increased fruit size by 19%, and increased percentage of cull fruit by one-third. The effect of pruning on early yield depended on the cultivar. Based on these results, pruning would be advised …
