The toxicity of 20 orchard chemicals at field rates was determined for all stages of Aphytis melinus in the laboratory. The insecticides Bacillus thuringiensis + surfactant, endosulfan, pirimicarb: the miticide cyclosulfyne : the herbicides and plant growth regulators dimazide, diuron, gibberellic acid: the fungicide copper oxychloride: the nutrient mixture zinc oxide, manganese sulphate and urea : and the surfactant nonyl phenol ethoxylate (9 Eto) appear safe for use in citrus groves containing A. melinus. The herbicide dalapon + surfactant and the fungicide Bordeaux mixture were moderately toxic to immatures, and the herbicide bromacil was moderately toxic to adults. However, it is considered that careful application of these treatments is safe. The organophosphorus insecticides azinphos-methyl, maldison and parathion; the insect growth regulator hydroprene; and the miticide cyhexatin were highly toxic to either juvenile or adult stages. White oil, recommended for integration with A. melinus, was highly toxic to immature stages. This anomalous result is discussed in terms of spray distribution and integrated control of red scale on citrus

AbstractThe postbloom and summer sprays recommended in Florida commercial citrus cultures for management of insect and mite pests and phytopathogenic diseases caused a significant (P < 0.05) reduction of citrus blackfly, Aleurocanthus woglumi Ashby, infesting urban dooryard citrus. There were no observed adverse chronic effects on populations of the parasite Amitus hesperidum Silvestri, or the predator complex consisting of spiders, chrysopids, and coccinellids attributable to the chemical treatments. The absence of chronic pesticide-induced interference with biological control agents was interpreted as an indication of the potential for development of integrated control strategies against A. woglumi should this insect invade commercial citrus areas in Florida.

Winter Time

In the unheated plastic greenhouses of Crete, the control of the greenhouse whitefly Trialeurodes vaporariorum Westwood using chemicals is usually needed during winter time. The systemic insecticide Vydate when applied as soil granules at the highest dose (2g/plant), gave protection for young eggplants against whitefly for a period of 5 weeks. Experiment with different chemicals showed that the new insect growth regulator Nomolt, is fairly effective in controlling the greenhouse whitefly when used in combination with Actellic. It gave equally good results when compared with a mixture of Applaud and Actellic.

Azinphos Methyl

The insect growth regulators tebufenozide and fenoxycarb were compared with the industry standard organophosphate, azinphos-methyl, in a replicated field trial. In both the 1992-93 and 1993-94 seasons, the 2 insect growth regulators maintained damage levels to harvested and windfall apples below 1% for both codling moth (Cydia pornonella L.) and lightbrown apple moth (Epiphyas postvittana Walker). This was despite considerable pest pressure as indicated by pheromone trap catches of both species. In the first season of the trial, E. postvittana was controlled more effectively (P<0.05) by tebufenozide than by fenoxycarb. In both seasons, populations of two-spotted mite, Tetranychus urticae Koch, and European red mite, Panonychus ulmi Koch, were higher in plots under azinphos-methyl treatment than in either insect growth regulator treatment. Neither insect growth regulator appeared to suppress populations of the phytoseiids Typhlodromus pyri Scheuten and Typhlodromus occidentalis Nesbitt. Limb jarring in the second season showed statistically significant (P<0.05) differences in populations of other predators which may have contributed to the biological control of phytophagous mites in the insect growth regulator treatments. Numbers of spiders, Stethorus spp., and apple dimpling bug (Carnpylomma liebknechti Girault) nymphs were all lower in the azinphos-methyl treatment. Results are discussed in relation to reducing dependence on conventional pesticides by use of more target-specific compounds which may be more compatible with biological control.

Physical And Chemical

Two experiments were conducted in the Nematology Laboratory of the Seed Pathology Centre and experimental field of the Department of Agronomy, Bangladesh Agricultural University (BAU), Mymensingh during 2004 to examine the influence of physical and chemical treatments on the seed borne nematode disease of rice. The integrated control with physical and chemical treatments against seed borne nematode (<i>Aphelenchoides besseyi</i>) causing white tip disease of rice varieties BR11 and Nizersial (T. Aman) rice revealed that farmer’s saved seeds of both the varieties treated simultaneously with brine solution, hot water and Furadan 3G resulted in enhanced plant height, root length, panicle length, number of grains per panicle, total number of spikelet’s per panicle,  grain yield and lower association of seed borne nematode. Better responses were found with farmer’s saved seeds treated with brine solution and hot water than field application of Furadan  3G, hot water treatment and treatment with brine solution having higher plant growth characters and yield of grains correspondingly with lower number of sterile and discolored spikelet’s and seed borne nematode compared to the control.The Agriculturists 2015; 13(1) 79-86
