Rhabditida is an order of free-living, zooparasitic, and phytoparasitic microbivorous nematodes living in soil.
A triazole refers to any of the heterocyclic compounds with molecular formula C2H3N3, having a five-membered ring of two carbon atoms and three nitrogen atoms. There are two sets of isomers that differ in the relative positions of the three nitrogen atoms. Each of these has two tautomers that differ by which nitrogen has a hydrogen bonded to it:

Tylenchorhynchus is a genus of nematodes including many species of plant parasites. The classification of stunt nematodes - those including the genus Tylenchorhynchus - is unstable; many newly discovered species within this genus are reconsidered to be actually subspecies. Stunt nematodes such as Tylenchorhynchus and the closely related genera, Anguillulina and Merlinia, include more than 250 known species. Members of these genera possess similar anatomy and may be easily mistaken for one another. Some debate has led to the classification of single species under different names in two distinct genera.
Leucania zeae is a species of moth of the family Noctuidae. It is found in North Africa, southern Europe, Turkey, Israel, Iran, Iraq, Saudi Arabia, central Asia and western China.
Grey leaf spot (GLS) is a foliar fungal disease that affects maize, also known as corn. GLS is considered one of the most significant yield-limiting diseases of corn worldwide. There are two fungal pathogens that cause GLS: Cercospora zeae-maydis and Cercospora zeina. Symptoms seen on corn include leaf lesions, discoloration (chlorosis), and foliar blight. Distinct symptoms of GLS are rectangular, brown to gray necrotic lesions that run parallel to the leaf, spanning the spaces between the secondary leaf veins. The fungus survives in the debris of topsoil and infects healthy crop via asexual spores called conidia. Environmental conditions that best suit infection and growth include moist, humid, and warm climates. Poor airflow, low sunlight, overcrowding, improper soil nutrient and irrigation management, and poor soil drainage can all contribute to the propagation of the disease. Management techniques include crop resistance, crop rotation, residue management, use of fungicides, and weed control. The purpose of disease management is to prevent the amount of secondary disease cycles as well as to protect leaf area from damage prior to grain formation. Corn grey leaf spot is an important disease of corn production in the United States, economically significant throughout the Midwest and Mid-Atlantic regions. However, it is also prevalent in Africa, Central America, China, Europe, India, Mexico, the Philippines, northern South America, and Southeast Asia. The teleomorph of Cercospora zeae-maydis is assumed to be Mycosphaerella sp.
Dickeya is a genus of the family Pectobacteriaceae that consists mainly of pathogens from herbaceous plants. Dickeya is the result of the reclassification of 75 strains of Pectobacterium chrysanthemi, as well as Brenneria paradisiaca CFBP 4178, into a new genus. The genus is named for American phytopathologist Robert S. Dickey. Several species in this genus, such as Dickeya dadantii, are known phytopathogens.
The corn cyst nematode (CCN) Heterodera zeae is a plant parasitic nematode that feeds on corn Zea mays. The CCN has a limited economic impact worldwide due to its high soil temperature requirements.
