The suitability of neem (Azadirachta indica), garlic (Allium sativum) and red chili (Capsicum frutescens) in repelling insects in dried fish during processing and storage was determined. Their acetone extracts were used to evaluate toxic effects against adult dermestid beetle, Dermestes sp. The concentration of plant extracts were 60%, 80% and 100% for adult Dermestes sp. The LC50 values of neem, garlic and red chili were 1.81%, 4.85% and 1.11%, respectively at 24 hours after treatment (HAT), indicating that red chili was the most toxic plant. Red chili possessed the highest toxic effect at 48 HAT (0.87%) and 72 HAT (0.03%). It was observed that all of the three plant extracts had repellent action on adult Dermestes sp. The highest mean repellency was observed in neem extract (62.67%) followed by red chili (38.44%) and garlic (31.11%). Repellent effects increased with the concentration of plant extracts.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16865 Progress. Agric. 20(1 & 2): 133 – 142, 2009

Chili plants is one of the leading horticultural commodities, but in increasing the production and quality of chili plants against pest attacks are not accompanied by good management and right, so this causes a decrease in the level of chili production. The aim of this research is to find out the combination reaction of garlic (Allium sativum), lemongrass (cymbopogon citratus) and soursop (Annona muricata) as natural pasticides against aphids (Aphis gossypll) of cayenne pepper (Capsicum frutescens). This research was conducted experimentally by using a Randomized Block Design (RBD) with 5 treatments of various kinds of concentrations namely 0%, 10%, 20%, 30%, and 40%; repeated five times. In this study the mixture combination was higher at a concentration of 40% with a mortality of 43.6%.Keywords:: chili plants, pest Aphids, natural pesticide.  ABSTRAKTanaman cabai merupakan salah satu komoditas hortikultura unggulan namun dalam peningkatan produksi dan kualitas tanaman cabai terhadap serangan hama tidak dibarengi dengan pengelolaan yang baik dan benar, sehingga hal ini menyebabkan menurunnya tingkat produksi tanaman cabai. Penelitian bertujuan megetahui reaksi kombinasi bawang putih (Allium sativum), serai (cymbopogon citratus) dan sirsak (Annona muricata) sebagai pastisida alami terhadap hama kutu daun (Aphis gossypll ) tanaman cabai rawit (Capsicum frutescens).  Penelitian ini dilakukan secara eksperimen dengan menggunakan Rancangan AcakKelompok (RAK) dengan 5 perlakuan macam konsentrasi yaitu 0% , 10% , 20% , 30% , dan 40%; diulang lima kali.  Pada hasil penelitian ini kombinasi campuran lebih tinggi pada konsentrasi 40% dengan mortalitas 43,6 %.Kata kunci: cabai rawit, kutu daun, pestisida alami

The present field experiment was conducted to determine the efficacy of consortium of different bio-agents viz., Psuedomonas fluorescens + Trichoderma harzianum + Bacillus megatherium, organic amendments viz., neem cake, poultry manure and nematicides viz., carbosulfan, carbofuran and fluensulfone for the management of M. graminicola under direct-seeded condition during kharif 2019-20 at the University of Agricultural and Horticultural Sciences, Shivamogga. The results revealed that all the treatments were significantly superior over the untreated check with respect to plant growth parameters and nematode population. However, the plots treated with fluensulfone at 3g/plot was found to be the best treatment as it recorded highest plant height (78.87 cm), root length (18.90 cm) with lowest RKI (2.0), maximum grain yield (36.87 q/ha) and least nematode population (199.00/200g soil) followed by the consortium of bioagents P. fluorescens + T. harzianum + B. megatherium at 20g/m2, carbofuran 3G at 9.9g/ m2, carbosulfan 25 EC at 0.1%, neem cake at 100g/m2 and poultry manure at 100g/m2 respectively.

<p>The use of chemical insecticides in crop production has resulted in increased food production in Africa, but their use has resulted in the destruction of beneficial organisms and development of resistance by some insects to the insecticides. The effectiveness of garlic <em>Allium sativum</em> and hot pepper, <em>Capsicum frutescens</em> in controlling the pests of cabbage, <em>Brassica oleracea</em> was evaluated. These botanicals were compared with a standard chemical insecticide Attack® (Emamectin benzoate). The experiment was conducted in a randomized complete block design, with 3 treatments and a control, each of which was replicated 3 times. <em>Plutella xylostella, Brevicoryne brassicae, Hellula undalis</em> and <em>Trichoplusia ni</em> were found on cabbage plants. Significantly fewer of them were found on the treated plants than the control plants. The use of the plant extracts resulted in a reduction in mortality ranging from 10.76% to 55.94%. Fewer natural enemies of <em>B. brassicae</em> were sampled on the insecticide-sprayed plots than the garlic and pepper-sprayed plots. The cost of protecting cabbage plants from insect infestation using Attack was higher than the botanicals. Garlic-treated plots recorded the highest cost: benefit ratio of 1:16 while Attack®-treated plots recorded the least of 1: 9.2. The control effects of the botanicals compared favourably with that of the chemical insecticides. Thus these botanicals can be used as substitutes to chemical insecticides.</p>

Acetone extracts of red chili (Capsicum frutescens), garlic (Allium sativum) and neem (Azadirachta indica) were used to evaluate their insecticidal effects against a dry fish beetle, Dermestes sp. larvae and a mite, Necrobia sp. adult. The concentration of plant extracts were 60, 80 and 100% for Dermestes sp. larvae and 10, 15 and 20% for Necrobia sp. adult. The mortality of Necrobia sp. at 24, 48 and 72 hours after treatment (HAT) indicated that red chili extract possessed the highest insecticidal effect followed by neem and garlic. Mortality was found to be directly proportional to the concentration of plant extracts. For Necrobia sp. (adult) LC50 values of red chili, neem and garlic were 0.78, 0.85 and 1.68%, respectively at 24 HAT. Red chili was found to possess the highest insecticidal effect among these three with the highest toxic effect at 48 HAT (0.29%) and 72 HAT (0.03%). For the larvae of Dermestes sp., the LC50 values of red chili was 0.60%, neem 0.69% and garlic 1.15% at 24 HAT, again indicating that red chili had the highest insecticidal effect on dry fish insects.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16756 Progress.

A field experiment was carried out in garlic (Allium sativum L.) in Randomized Complete Block Design (RCBD) with four replications and five treatments in horticulture farm of Agriculture and Forestry University, Chitwan, Nepal to find out the efficacy of different combination of poultry manure and Urea as nitrogen fertilizers in its yield and yield attributes. The five treatments used for experiment were designed altering the recommended nitrogen dose through different sources i.e. (T1) 100% Urea, (T2) 7% Urea and 25% poultry manure, (T3) 50% Urea and 50% poultry manure, (T4) 25% Urea and 75% poultry manure and (T5) 100% poultry manure. The data regarding to the plant height, number of cloves, diameter of bulbs and fresh bulb weight were taken. In case of plant height, non-significant result was found between various treatments. The number of cloves was found highest in T5 (24.69±1.30), the diameter of bulb was found highest in T2 (3.93±0.39 cm), fresh bulb weight was found highest in T2 (14.32±0.39 gm) and total bulb yield was found highest in T2 (7.16±0.19 t/ha) which were significant at 5 % level of significance. The total bulb yield was found positively correlated (r=0.53) with diameter of bulb at 1 % level of significance. The benefit cost (B/C) ratio was found highest in T2 (1.54) and lowest in T3 (1.28). So 75% Urea and 25 % Poultry Manure stood one of the best combinations of nitrogen fertilizers providing higher economic yields.
