Field trials were conducted at Umudike, Nigeria, during the 2015 and 2016 cropping seasons to determine the efficacy of plant extracts from seven plant species against field insect pests of mung bean, Vigna radiata L. Wilczek. The extracts tested were obtained from scent leaf (Ocimum gratissimum), neem leaf (Azadirachta indica), bitter leaf (Vernonia amygdalina), garlic (Allium sativum), turmeric (Curcuma longa), plantain (Musa paradisiaca) peel and Negro pepper (Xylopia aethiopica). Karate (Lambda-cyhalothrin EC) at 50 mL was introduced as a check in the trials. The experimental design was a randomised complete block design (RCBD) with three replicates. Data were collected weekly on the insect population densities, yield and yield components. The results indicated that all the treatments were effective against mung bean insect pests (Aphis craccivora [aphid], Bemisia tabaci [whitefly], Amrasca biguttula biguttula [jassid] and Zonocerus variegatus[grasshopper]). There was a significant (p ≤ 0.05) reduction in the population of insects on the plots treated with plant extracts and karate in 2015 and 2016 cropping seasons. The population densities of grasshoppers in 2015 and whitefly in 2016 were significantly lower in the treated plots compared with the control plots. Azadirachta indica and C. longa extracts recorded the highest seed yield of 50.00 kg/ha and 42.33 kg/ha in 2015 and 2016, respectively. No significant differences were observed between the plant extracts and karate, which recorded significantly higher yields when compared with the control (23.30 kg/ha). All the plant extracts used exhibited insecticidal activity against the insect pests of mung bean. It is, therefore, recommended that these plant extracts can be used for the control of mung bean insect pests to achieve sustainable production, food security and quality.

A field study was carried out during the two cropping seasons of okra to investigate the efficacy of plant extracts and synthetic insecticides applied singly and synergistic effect of botanicals with the synthetic insecticide on some insect pests of okra. Plots were arranged in a Randomized Complete Block Design (RCBD), with three replications. Three insect pests of okra (Podagrica uniformis, Podagrica sjostedti and Zenocerous variegatus) were observed on the field. Cypermethrin applied singly and Cypermethrin combined with plant extracts effectively controlled observed insect pests, followed by lone application of plant extracts (L camara, T. vogelii and Z. officinales plant extracts at 1st and 2nd season. Okra yield revealed that both plant extract and Cypermethrin combined with plant extract were not significantly different from one another at first season and at second season Cypermethrin combined with plant extracts performed better than Cypermethrin applied singly. This study indicates that the studied plant extracts can be good synergist for Cypermethrin in controlling field pest of okra.

<p>The effects of ethanolic extract of neem, <em>Azadirachta indica</em> (Meliaceae), seeds and petroleum ether extract of <em>Lantana camara</em> leaves (Verbenaceae) on the populations of three cabbage pests, <em>Plutella xylostella</em>, <em>Brevicoryne brassicae</em> and <em>Hellula undalis</em> were studied. The study was conducted between January and April 2008. Extracts of the two plants were sprayed on cabbage plants to control these pests. A standard synthetic chemical insecticide (Mektin) was used as reference product. The experiment was conducted in a randomized complete block design and each treatment was replicated four times. The effects of plant extracts on the population dynamics of the pests’ species, the level of infestation and yield were assessed. Significantly more of the pests infested the control plants than the treated plants (<em>P</em>&lt; 0.01). The mean weight of cabbage heads on the sprayed plots was significantly heavier than that of the control unsprayed plots. The use of <em>A. indica</em> seeds and <em>L. camara</em> leaf extracts increased yield by 37.05% and 25.80%, respectively. Spraying the cabbage plants with the plant extracts significantly reduced the numbers of pests compared with the control plants. The use of these plant extracts can be incorporated into an overall control programme of these pests.</p>

Tillage Methods

<p>The objective of this research was finding the answer to comprehend the influence of herbicide kinds, tillage methods, and interaction between them on the growth and yield of mung bean (<em>Vigna radiata</em> L). The thinking background of this research is that mung bean is not tolerant with weed competition, meanwhile herbicide that can control weed on mung bean crop hasn’t been found yet. Sometimes tillage is need to control weed, too. But the effect of tillage on increasing the yield of mung bean hasn’t been completely recognized.</p><p>The research was carried out in Karangasem village, Surakarta, in about 106 meter height sea level water, at Entisol soil. The research was designed with Randomized Completely Block Design (RCBD) that arranged according to Split Plot Design, that had 2 factors with 12 treatment combinations and every combination was replicated 4 times. The first factor was tillage method as main plot, that had 3 levels as follow: no-tillage method (P0), one time tillage method (P1), and two times tillage method (P2). The second factor was herbicide kind as sub plot, that had 4 levels as follows: control (H0), Isopropylamine Glyphosate herbicide/Roundup (H1), Oxadiazone herbicide/Ronstar 250 EC (H2), and Oxyfluorfen herbicide/Goal 2E (H3). The result was analyzed with Analysis of Variance on 1% and 5% level and then analyzed with Least Square Design (LSD) test if Anova test showed significant result.</p><p>From the result of this research, we can concluded that Roundup is able to increase total mature pods and dry seed weight of mung bean, but not significantly affecting all other research variables. Goal and Ronstar can make the plant height and fresh plant biomass of mung bean lower, and not significantly affecting total mature pods, total immature pods, total unfilled pods, dry seed weight, and 100 dry seed weight of mung bean. Meanwhile Ronstar is not significantly affecting. Goal can make the dry plant biomass of mung bean lower. The tillage method treatments and interaction between tillage method and herbicide kind treatments is not significantly affecting all studied variables.</p>

The Impact

ABSTRACT Water stress is known as the major threat to reduced growth and yield of plants in arid and semi-arid regions. Potassium is one of the indicators of plant responses to water stress. To evaluate the impact of water stress and levels of potassium on yield and yield components of two varieties of mung bean (Vigna radiata) (promising lines VC6172 and Indian), an experiment in the form of split factorial, based on randomized complete block design with three replicates was conducted in 2011, at the research farm of Safi-Abad Dezfool, Iran (latitude 32°16’ N, longitude 48°26’ E and altitude 82.9 m above sea level) .Water stress in three levels: irrigation at 120 (no stress), 180 (moderate stress) and 240 (severe stress) mm evaporation from pan, were allocated to the main plots and potassium fertilizer at three levels (0, 90, 180 kg /ha) and two varieties of mung bean (promising line VC6172 and Indian) were allotted to the sub-plots. Results showed that water stress and potassium fertilizer significantly affect all traits. The highest grain yield (2093 kg /ha) was obtained from no stress treatment in the case of 180 kg /ha potassium. Total dry matter, number of pods and grain yield, were significantly different between the two varieties. The interaction between fertilizer and variety, on dry matter and grain yield and the interaction between irrigation and variety, on dry matter were significant. We conclude that use of potassium fertilizer can reduce the adverse effects of water stress.

The present study aimed to evaluate the insecticidal activity of hydroalcoholic plant extracts on Aphis craccivora Koch nymphs in cowpea. The experiments were carried out under greenhouse conditions in a randomized block design with five repetitions. Hydrated ethanol was used as a solvent in the botanical extract preparation. Cowpea plants were infested with five female adult aphids, eleven days after planting. After 48 hours, the adults were removed from the plants, leaving the recently bred nymphs. The evaluation of the nymphs’ survival was carried out forty-eight 48 hours after the application of the plant extracts. The botanical extracts with more than 50% efficiency were: Allium tuberosum leaf, Caesalpinia ferrea leaf, Piper aduncum leaf, Carica papaya seed, Dieffenbachia picta leaf, Cucurbita moschata seed and the control treatment, Annona squamosa seed. The botanical extracts with less than 50% efficiency were: Allium sativum bulb, Anacardium occidentale leaf, Borreria verticillata leaf plus flower, Coffea arabica leaf and seed, Delonix regia leaf and flower, Euphorbia tirucalli leaf, Leucaena leucocephala leaf, Mimosa caesalpiniaefolia leaf, Nerium oleander leaf, Syzygium cumini leaf, endocarp and pericarp, Syzygium malaccense leaf, Zingiber officinale rizome and Ziziphus joazeiro leaf. The highest efficiency levels were obtained by D. picta and C. moschata, rendering these extracts suitable for field trials to further evaluate their efficieny against the cowpea black aphid.

SUMMARYField trials were conducted in 1988 at the University of Ibadan to determine the effects of cypermethrin + dimethoate (Sherpa Plus®), the oil extract from ripe seeds of Piper guineense Schum & Thonn and the aqueous extract of ripe seeds of Azadirachta indica A. Juss on the pests and yield of cowpea. Cypermethrin + dimethoate was consistently superior to all other treatments in substantially reducing the population densities of Megalurothrips sjostedti Trybom and of Maruca testulalis Geyer, which are serious pests on flowers and buds, and in reducing the densities of four pod-sucking bugs. Pest population densities were also reduced by foliar sprays with A. indica or P. guineense extracts.Seed yield after treatment with cypermethrin + dimethoate was 0·99 t/ha, more than double the yield from other treatments. A marginal increase in seed yield compared with the control was achieved by foliar spraying with A. indica extract.

And Performance

Okra, an economically important vegetable crop with numerous benefits to human, is often attacked by large number of insect species. These insect species cause direct damage to okra plants and also serve as vectors of diseases resulting in economic loss. Control of these insect pests given reducing hunger and poverty, and fostering agricultural ecosystems becomes imperative.  This study aimed at the use of indigenous medicinal plant and a sub-lethal dose of synthetic insecticide to check the invasion of pests and performance of okra. The field laid in a randomized complete block design of four treatments replicated three times. The treatments included; Curcuma longa 5%, Curcuma longa 20%, lambda-cyhalothrin, and a control. Data were collected on insect pest species recovered after treatment application and yield of okra. All data were subjected to analysis of variance and differences between the treatment means were separated using Duncan’s multiple range test. C. longa (20%) compared effectively with the sub-lethal dose of lambdacyhalothin (0.5 ml/l) in their attack against the targeted pests. Although higher number and weight of pods were harvested from synthetically treated plots, the C. longa treated plots produced significantly higher number and weight of harvested pods when compared with untreated plots. Water extract of the rhizomes also conferred some protection against okra pests; we recommend that farmers in Ekiti State adopt this botanical against the notorious flea beetles especially when the profits accrue from okra sales outweigh their net investment.

Cabbage (Brassica oleracea Linn.) is one of the important vegetables grown worldwide. Insect pests have been a major constraint to its production with some reported to have developed resistance to commonly available synthetic insecticides. In order to find alternative control for these pests, field experiments were conducted in the early seasons of 2011 and 2012, to evaluate the efficacy of three plant extracts, Tephrosia vogelli Hooks, Zingiber officinales Rosh and Lantana camara Spanish flag, applied at 5, 10 and 25 % w/v concentrations Delthamethrin (a synthethic insecticide) and an unsprayed plot were included as positive and negative controls respectively. Plots were arranged in a Randomized Complete Block Design (RCBD), with three replications. Mean Data over the two planting seasons were subjected to the analysis of variance and significant means were compared using the least significant difference (L.S.D) at P < 0.05. Z. officinales extract effectively control P. xylostella larvae at all concentrations with 25 % w/v gave the best yield of 0.50 kg/ha while T. vogelii and L. camara extracts were as effective as Deltamethrin at different concentrations and hours on diamondback-moth (P. xylostella) adult The present findings indicated that effective botanicals against Diamondback moth adult and larvae of cabbage can be formulated from extract of T. vogelii, L. camara and Z. officinales at 25 % concentration respectively.

Despite the fact that synthetic insecticides are fast acting, they constitute environmental hazard thereby necessitating the use of ecologically based alternative such as plant based insecticide. This experiment was conducted during the late and early planting seasons of 2011 to determine the insecticidal efficacy of Tephrosia vogelii and Moringa oleifera extracts at three tested concentrations (5, 10 and 20% v/v) against insect pests of watermelon. The experiment was set up in a randomized complete block design with three replicates. The results showed that M. oleifera extracts had 62% reduction of Phyllotreta cruciferae compared with T. vogelii which had 45% control. However, T. vogelii extracts had 64% control of Diabrotica undecimpunctata and Bactrocera curcubitea but M. olefera extracts had 50% control. The plant extracts proved effective against studied insects when compared with untreated plots. However, the effectiveness of the two plants extracts were concentration dependent. Therefore, the two plant extracts can be used in the control of insect pests of the watermelon
