ABSTRACT Establishing an adequate stand of peanut (Arachis hypogaea L.) and minimizing the negative impact of tobacco thrips [Frankliniella fusca (Hinds)] is important for maximizing yield in both organic and conventional production systems. The incidence, severity, and impact of soil borne pathogens and thrips populations on peanut may be influenced by planting date, fungicide seed treatment, and/or systemic insecticide application. However, the interaction of these management techniques has not been investigated in North Carolina with Virginia market type cultivars to date. As such, research was conducted over four years in North Carolina to determine peanut stand, injury caused by tobacco thrips feeding, and pod yield as influenced by planting date (early, mid-, and late-May), fungicide seed treatment, and phorate applied in the seed furrow at planting. Peanut stand increased when planting fungicide-treated seed compared to non-treated seed, although the magnitude of this effect lessened with later May plantings. Regardless of phorate treatment, less thrips injury was noted when peanut was planted in mid- or late-May compared with early May in three of four years. Yet the addition of phorate in-furrow further reduced thrips injury at every planting date. Peanut yield increased 75% and 50% of the time when seed was treated with fungicide and phorate was applied in the seed furrow at planting, respectively. Yield was generally greater when peanut was planted in mid-May and late-May compared to planting in early May irrespective of fungicide seed treatment or phorate treatment. Peanut stand was negatively and positively correlated with observed thrips injury and peanut yield, respectively. Additionally, peanut yield was negatively correlated to thrips injury. These data suggest that conventional producers should utilize treated seed and phorate in-furrow for thrips management regardless of planting date and that organic producers should plant in late May to minimize negative impacts of thrips and soil borne pathogens.

Integrated control of  ginger wilt disease  (Ralstonia solanacearum Smith) and root knot nematodes (Meloidogyne spp.). The purpose of this research was to obtain  reasonable integrated control ginger wilt disease. The research was conducted in endemic area of ginger wilt disease at Biaung village, Penebel Regency during April, 2003 to Januari, 2004. Randomized block design (RAK) with three replication and 11 treatments was used in this experiment. Research result appears that ginger wilt diseases can be controlled by integrated control using seed treatment with soaked method in urea-polymer + Bacillus sp. (2g/l water for two hours and then for planting treatment with vermi-compost (150g/plant) + fire-wood ash (50g/plant) + Mycorrhiza (100 g/plant). Root knot nematode (Meloidogyne spp.) was effective controlled by dolomit (5g/plant) + seed-treatment with bactericide (Agrimicin 500 ppm) +  vermi-compost (150 g/plant).

Effectiveness of three biopesticides viz., Biowilt-X (based on Trichoderma harzianum), Bionem-X (based on Pochonia chlamydosporia) and Biocure-X (based on Bacillus subtilis) were tested against wilt (Fusarium oxysporum f. sp. ciceri), root-knot (Meloidogyne incognita) and the wilt disease complex (F. oxysporum f. sp. ciceri + M. incognita) of chickpea (cv. BG-256). The biopesticides were developed by involving novel technology patented in USA and India and were applied to seeds (5 g/kg seed) and soil (40 g/microplot) to evaluate their effectiveness against the target diseases under field conditions. The pesticides viz., carbendazim and nemacur were applied @ 1.25 kg a.i./h and 6.0 kg a.i./h as soil application, and 2g/kg seed as seed treatment. Chickpea grown in the plots infested with pathogens singly or concomitantly developed characteristic wilt and root-knot symptoms, and exhibited significant yield decline. Application of biopesticides checked the severity of the diseases and the resulting yield declines. Application of Biowilt-X decreased the wilt incidence by 60% and promoted the yield of chickpea (46%) grown in F. oxysporum f. sp. ciceri infested plots. The biopesticides Bionem-X and Biocure-X were found effective against root-knot disease and suppressed the galling by 20 and 12% and promoted the yield of infected chickpea plants by 28 and 34% in comparison to the control. Application of Biocure-X was found highly effective against the fungus-nematode wilt disease complex; its seed treatment substantially controlled the wilt and root-knot, and increased the yield of concomitantly infected chickpea by 49°C. Biocure-X was found more effective in increasing the nodulation as compared to other treatments. Effect of carbendazim and nemacur was significant (P Less Than 0.05) in checking the wilt, root knot and disease complex but were not as effective as biopesticides. The present study has demonstrated that biological management of wilt, root-knot and disease complex can be successfully achieved with the application of the developed biopesticides.

Field experiments were conducted during Kharif seasons of 2013 and 2014 in the farmer's field of Gariyaband, Chhattisgarh, India to find out different integrated management levels of control schedule for pigeonpea wilt disease. All treatments had a significant effect on germination percent, disease incidence, seed yield and disease index in both the consecutive years of experimentation. T4–Seed treatment with Thiram + Carbendazim+ Trichoderma viride + Rhizobium + Soil application of Trichoderma viride, resulted in higher germination percentage (96.8 and 97.2), wilt incidence percent at 60 DAS (2.97 and 3.15), wilt incidence per cent at 150 DAS (9.68 and 7.65) and seed yield (15.10 and 16.28 q ha-1) during 2013 and 2014, respectively and was found superior over rest of the treatments. The loss in pigeonpea yield was up to the tune of 18.86 to 54.24% due to the incidence of wilt disease.

The Imidacloprid insecticide, Gaucho 70 WS at 1.5, 2.5, 3.5, 4.5 and 5.5 g/kg seed was used as seed treatment and monocrotophos 40 WSC at 1120 ml/ha was applied as foliar spray on CB9 cotton cultivar to suppress aphid, whitefly and thrips, and impact on their natural enemies during 2008-2011 at the Regional Cotton Research Station, Dinajpur, Bangladesh. The activity of natural enemies, such as ladybird beetle, lacewing, syrphid, and spider population on the sucking pests attacking cotton cultivar CB9 and yield of cotton were recorded. Imidacloprid significantly reduced aphid, whitefly, and thrips population on cotton crops compared to untreated control or foliar spray of monocrotophos 40 WSC at 1120 ml/ha. Ladybird beetles, lacewings, syrphids, and spiders were abundant in the field but their population decreased in the treated plots compared to untreated control. The CB9 cotton cultivar produced significantly higher yield (1.73 t/ha) with a benefit cost ratio 12.47 when seeds were treated with Imidacloprid at 5.5 g/kg fuzzy seed. This study indicated that Imidacloprid (Gaucho 70 WS) used as a seed treatment may be suggested to the cotton growers for controlling sucking pests. Bangladesh J. Agril.
