The phaseout of methyl bromide and the ban on, or withdrawal of, other toxic soil fumigants and non-fumigant nematicides belonging to the organophosphate and carbamate groups are leading to changes in nematode-control strategies. Sustainable nematode-control methods are available and preferred, but not always effective enough, especially for cash crops in intensive agriculture. A few non-fumigant nematicides, which have a relatively high control efficacy with a low toxicity to non-target organisms, have been released to the market or are in the process of being registered for use. Fluensulfone, fluopyram, and fluazaindolizine are the three main and most promising next-generation nematicides. In this paper, several aspects of these non-fumigant nematicides are reviewed, along with a brief history and problems of old-generation nematicides.

Reproduction on Asclepias curassavica, Acmella oppositifolia, T. microglossa, and T. jalisciensis was poor. Root galling on a successive tomato crop was severe in pots previously planted with T. jalisciensis, moderately severe after T. microglossa and A. oppositifolia, light after T. filifolia and B. pilosa, and with no galling following A. curassavica, L. camara, M. divaricatum and L. virginicum.

Cotton flea beetle, Podagrica puncticollis is the most destructive insect pest of cotton in north-western part of Ethiopia. This study was conducted to identify and determine the host range of cotton flea beetle in Metema area. The field survey was undertaken from June 27, 2015 to January 9, 2016 in ten kebele administrations of the district. At least three fields were prospected after every 15 days, in each kebele for host plants as well as to determine population density and percent leaf damage by adult cotton flea beetle, at different growth stages of cotton plant. The composition of plant species with damaged symptom or infested by flea beetle was analysed using quantitative means and identified by comparing specimens with description of identification manuals. A total of 11 host plant species of cotton flea beetle were identified in the cotton growing areas of Metema throughout a season. Indigofera longibarbata (Fabaceae), Hibiscus articulatus, H. cannabinus, H. vitifolius, Abutilon figarianum, Sida alba and S. urens (Malvaceae), Bidens pilosa and B. setigera (Asteraceae), Corchorus olitorius and C. trilocularis (Tiliaceae) found to be common host plants of cotton flea beetle. Thus, among the host plants, H. vitifolius, H. cannabinus, H. articulatus, C. olitorius and C. trilocularis were the most suitable hosts for adult cotton flea beetle in respect of the number of adults per plant and percent foliage damage they sustained. These findings could aid in developing longterm management strategies for this important insect pest existing in a hot dry tropical environment of north-western Ethiopia.

Field experiments for the chemical control of the pickleworm (Diaphania nitidalis), the melonworm (D. hyalinata), the leafminer (Liriomyza sativae), and nematodes (Meloidogyne incognita and Rotylenchulus reniformis) on cucumber cultivar Ashley were established in two locations in Puerto Rico in 1979 and 1980. In the second test, a lower number of mined leaves was observed on methamidophos-treated plots as well as a significant lower index of leafminer damage. All chemicals controlled the pickleworm effectively. Highest yields were obtained from plots treated with the highest dosage of acephate and with the intermediate dose of methamidophos. Applications of carbofuran, acephate, methomyl and permethrin reduced the melonworm damage in the third test. Highest yields were obtained from carbofuran-treated plots. All nematicides controlled nematodes in the soil.

Coffee Cultivation

Coffee (Coffea spp.) is one of important industrial crops. Additionally, arbuscular mycorrhizal fungi (AMF) provide many benefits for plants such as increasing nutrient uptake, enhancing tolerance in drought and stress condition, etc. Therefore, preservation and propagation of AMF spores collected from coffee’s rhizosphere are necessary for coffee cultivation. The AMF preservation on coffee plant is not feasible because coffee is a long-term plants, which led to study on symbiotic ability of AMF on several short-term host plants (maize (Zea mays), plantain (Plantago spp.), rice (Oryza sativa), beggarticks (Bidens pilosa), and bahia grass (Pensacola bahia)) to maintain AM association. Investigation of symbiosis ability with four types of AMF spores showed that maize had the highest rate of fungal infection. The total number of AMF spore per 50g soil after 3 months of inoculation on maize reached 352 spores, which was 4.1 times higher than that of the origin while the lowest figure recorded in bahia grass is with only 2.3 times.
