The impact of 10 Fusarium species in concomitant association with Rotylenchulus reniformis on cotton seedling disease was examined under greenhouse conditions. In experiment 1, fungal treatments consisted of Fusarium chlamydosporum, F. equiseti, F. lateritium, F. moniliforme, F. oxysporum, F. oxysporum f.sp. vasinfectum, F. proliferatum, F. semitectum, F. solani, and F. sporotrichioides; Rhizoc...

The microbial degradation of aldicarb was examined in the greenhouse using soil from four cotton fields with a history of aldicarb use. The addition of aldicarb at 0.59 kg a.i./ha to natural soil increased Rotylenchulus reniformis numbers 6.6% in one soil and decreased R. reniformis numbers only 25.8% in another soil as compared to the corresponding natural soil without aldicarb. The use of inc...

A survey was conducted over a 22-year period to evaluate the influence of soil texture and land use on the geographical distributions of Rotylenchulus reniformis, Meloidogyne incognita, and Tylenchulus semipenetrans in the lower Rio Grande valley. The distributions of R. reniformis and M. incognita were related to soil texture, whereas T. semipenetrans occurred wherever host plants were present...

The effect o f soil temperature on parasitism and development of Rotylenchulus reniformis on resistant ('Peking' and 'Custer') and susceptible ('Hood' and 'Lee') soybean (Glycine max) cultivars was studied. Soil temperatures of 15, 21.5, 25, 29.5 and 36 C +/- 1 C were maintained in temperature tanks in a greenhouse. R. reniformis developed best at 25 and 29.5 C. The female life cycle can be com...

The reniform nematode (Rotylenchulus reniformis Linford & Oliveira) is an important problem in U.S. cotton, and all cultivars support high R. reniformis populations. The objectives of this research were to find better sources of resistance to R. reniformis than are known within G. hirsutum L. and G. barbadense L. and to determine if any of these sources are also resistant to the root-knot nemat...

Lentibulariaceae is the richest family of carnivorous plants spanning three genera including Pinguicula, Genlisea, and Utricularia. Utricularia is globally distributed, and, unlike Pinguicula and Genlisea, has both aquatic and terrestrial forms. In this study we present the analysis of the chloroplast (cp) genome of the terrestrial Utricularia reniformis. U. reniformis has a standard cp genome ...

Rotylenchulus reniformis is one of 10 described species of reniform nematodes and is considered the most economically significant pest within the genus, parasitizing a variety of important agricultural crops. Rotylenchulus reniformis collected from cotton fields in the Southeastern US were observed to have the nematode parasitic bacterium Pasteuria attached to their cuticles. Challenge with a P...

The relationships between Rotylenchulus reniformis population densities and pineapple growth and yield were studied in a small-plot field experiment. Increasing rates of handgun-injected 1,3-dichloropropene (1,3-D) preplant fumigant from 0 to 337 liters/ha resulted in greater nematode control, faster plant growth, and larger pineapple fruits. Rotylenchulus reniformis population densities at 2, ...

Fruit wastes of apple (Malus pumila), banana (Musa paradisiaca), papaya (Carica papaya), pomegranate (Punica granatum) and sweet orange (Citrus sinesis) @ 20g/plant and the fungal biocontrol agent Paecilomyces lilacinus @ 2g (mycelium+spores)/plant, alone and in combination were evaluated for the management of reniform nematode, Rotylenchulus reniformis infecting chickpea under glasshouse condi...

The reniform nematode, Rotylenchulus reniformis Linford &Oliveira, has become a serious threat to cotton (Gossypium hirsutum L.) production in the United States during the past decade. The objective of this study is to isolate fungi from eggs of R. reniformis and select potential biological control agents for R. reniformis on cotton. Soil samples were collected from cotton fields located in Jef...
