Abstract

This research was conducted to evaluate the effectiveness of crab shell powder and chitosan to control Fusarium wilt disease on bananas and to analyze the involved control mechanisms. The effectiveness of crab shell powder and chitosan to F. oxysporum f.sp. cubense was examined in a laboratory (in vitro) and greenhouse (in planta). In vitro evaluation showed that chitosan has an antifungal effect while crab shell powder did not. Application of crab shell powder and chitosan suppressed the disease in green house test. The concentrations of crab shell powder and chitosan that most effective to control Fusarium wilt incidences were 0.25% and 0.10% with an efficacy rate of 66.7% and 83.3%, respectively. The highest disease severity reduction was showed by crab shell powder 0.25% and chitosan 0.50% with an efficacy rate of 56.8% and 59.4%, respectively. Suppression of the disease might be due to the fungicidal effect of chitosan and the increase of the total population of bacteria and chitinolytic bacteria in the rhizosphere when banana seedling roots were treated with crab shell powder or chitosan. Experiment results using the split roots technique exhibited the role of crab shell powder and chitosan potentially to induce the resistance of banana to Fusarium wilt.

Abstract

Sustainable agriculture requires nutrient management options that can increase crop yields that are profitable for N nutrient availability and are environmentally friendly. However, N nutrient is dynamic and easy to lose, and excessive use of chemical N fertilizers has a negative impact on the environment. Biofertilizer by rhizobacteria is an effective way to maintain a reliable N-supply for rice growth. This study investigates the effect of a different combination of rhizobacterial fertilizers on nitrogen ion concentration in the soil and total rice production. The field experiment was conducted in two seasons. There were three treatments, including PGPR with 25% CF, PGPR with 50% CF, and 100% CF. The soil sample was taken from each treatment in six growth stages of rice i.e. 15, 36, 50, 72, 100, and 118 days after transplanting. Soil chemicals NH4+ and NO3- were analyzed by Ion Chromatography. The results showed that the uniformity of NH4+ and NO3- in the soil were the highest in fertilizer application with PGPR. The application of PGPR with 50% CF confirms that it can increase rice yields by 25.5% and 12.9%, respectively. The application of rhizobacteria can reduce the use of chemical fertilizers.

Abstract

Cassava is susceptible to waterlogged soil. In order to find the right variety for breeding purposes, a research needs to find proper screening parameters. They must be easy, fast, and economical practice. Therefore, in this research, upper-ground morphological responses of cassava to water deficit conditions in tissue were evaluated as traits to screen cassava breeding lines for water-logging tolerance. Hanatee variety is a landrace grown in the well-watered field for cooking purpose and was bred with Kasetsart 50 which is a high yielding commercial variety. These two varieties together with five breeding lines have water-logging tolerance potential in the field. They were evaluated in the pot for waterlogging stress at two vegetative growth stages at 105 DAP and 165 DAP for 12 days in each stress period. Among these seven varieties/lines, there were no varieties/lines showing waterlogging tolerance under this condition over others, but all showing recovery response. The results indicated that cassava at the vegetative growth stage had a recovery mechanism for the upper-ground parts, but not for the storage root tissue after waterlogging stress for 12 days. There was a potential of using the ratio of leaf retention to screen cassava germplasm or breeding lines for waterlogging tolerance.

Abstract

This study aimed to get the best irrigation method and determine the best time-effective provision of water to maintain optimum soil moisture for increase soybean crop production. This research was conducted in the field in Maros District, South Sulawesi. The experiment used a split-plot design and was repeated three times. The main plot was an irrigation method, namely the Scatter irrigation, Furrow, and Flood irrigations method, and its plot was the time of irrigation, namely every 15 days of age, at the period of 15 days, and full flowering and irrigation every 10 days. The results showed that the watering technique using the waterlogging method at the time at the age of 15 days and full flowering had the potential to increase the yield production of soybean, that was the number of pods 164.95 pieces, the weight of seeds 37.11 g, and production 4.64 t/ha. The inundation method was more effective in maintaining soil moisture and twice the application time. But in an optimal amount (229 l/time) was very effective in maintaining soil moisture.

Abstract

Purple blotch disease caused by Alternaria porri is the main destructive foliar disease of genus Allium, causing significant losses in yield of the crops. Recently, purple blotch disease is controlled by synthetic fungicides. However, fungicides have negative effects on the environment. Endophytic fungi can be used as an alternative control because a close symbiosis with the internal tissue of the host can minimize competition in new and complex ecosystems. This study aimed to explore and identify endophytic fungi that have the highest inhibition ability against A. porri and investigate the antagonistic mechanism. The method used in this study is an exploration of endophytic fungi, isolation of A. porri, in vitro antagonism tests, observation of the antagonistic mechanism, extraction of crude protein, SDS-PAGE, and identification. The antagonistic fungi that had the highest inhibition ability were identified as Penicillium citrinum with an inhibitory of 60.04%. Crude protein extracted from P. citrinum which showed inhibitory activity against A. porri is saturation level of ammonium sulfate 80% with a molecular weight of 40 kDa. This study implies that P. citrinum can inhibit the growth of A. porri through its anti fungi compounds. Further in vivo assays or field trials will need to be conducted in future studies.

Abstract

Helopeltis bradyi is a significant pest that causes yield losses and reduces the quality of tea plantations by piercing and sucking the sap of tea leaves. This pest can be appropriately controlled by using resistant clones. The PGL series (clones) owned by Pagilaran plantation has high yield and quality. However, information their resistance level against H. bradyi is limited. This research was conducted at Pagilaran tea plantation at an altitude of 990 masl. Six PGL clone series (PGL 4, PGL 6, PGL 9, PGL 10, PGL 11, and PGL 15) and control clones (TRI 2025 and Gambung 7) were used as plant materials. Their morphological and biochemical characteristics were determined to evaluate their resistance level against H. bradyi. The results revealed that the score symptoms (under 10%) of PGL 4, PGL 9, PGL 10, PGL 11, and PGL 15 clones were the lowest, so these clones were categorized to be highly resistant. In addition, the total phenol content and trichome density of PGL 4, PGL 10, and PGL 15 clones were the highest. Among them, the PGL 4 clone had the thickest epidermis. These characteristics likely contributed to the morphological and biochemical defence mechanisms of tea plants against H. bradyi.

Abstract

The application of essential oils to storage pest control requires an appropriate formulation formed by biodegradable compounds. This formulation should protect essential oils from degradation and evaporation while simultaneously allowing sustained release. This study aims to characterize nanoparticles loaded by clove essential oil-based polymer polyethylene glycol (PEG) and to investigate their insecticidal activity. In this study, clove oil solid dispersion was prepared using the fusion or melting-dispersion method with polyethylene glycol 6000 (PEG 6000) to form a binary solid dispersion system. The ratio of 10% of clove oil to PEG was optimal and had low PDI, small size, and the highest clove oil loading efficiency. Their size changed from 179 to 197 nm after 24 weeks of storage and the loading efficiency decreased for about 36%. Clove oil formulation in nanoparticles could not enhance the toxicity of clove oil but yet still showed high contact toxicity to C. ferrugineus. These formulations also have the slow and persistent release of the bioactive.

Abstract

Theresistance mechanisms exhibited by the five selected maize varieties against Ostrinia furnacalis [Gueene] or the Asian corn borer (ACB) were identified and evaluated in the study in terms of the insects’ percent mortality and development. The detached leaf-feeding assay was used in the experiment and laid out in Complete Randomized Design (CRD) with 5 treatments and replicated three times. Findings among the five selected maize varieties tested against ACB, Bt corn had exhibited a high degree of antibiosis mechanism. This was expected because of the Bt toxin from the maize variety conferring toxicity to Lepidopterous insect pests like ACB. A similar result with Variety 4 (Yellow Dent corn) was observed which shows a high degree of antibiosis mechanism that is innate within the maize leaves of the variety. Variety 1 (UPLB Lagkitan), Variety 2 (Yellow corn), and Variety 3 (White corn) show high susceptibility to ACB. Tolerance of the corn varieties to ACB needs to be further investigated because it is unknown to date whether the varieties possess or lack plant tolerance characteristics. Leaf whorl feeding assays used in the study only measure the antibiosis and antixenosis mechanisms in maize. Furthermore, a test to measure tolerance mechanisms is suggested among the maize varieties.

Abstract

Organic chilli peppers (Capsicum annuum cv. Superhot) at full-red stage were submeged in 50°C water for 4 minutes followed by surface coating with carboxymethyl cellulose (CMC) or chitosan at 0.25-1.0% for 2 minutes. The fruits were then packed in 32-34 µm thick polyethylene bag (Active PAKTM) before cold storage at 10°C for 12 days followed by 5 days holding at 25°C. The decrease of fruit quality was due to weight loss and decay and these could be reduced by edible coating. Coated fruit had higher titratable acidity, vitamin C content, total phenols, and activities of phenylalanine ammonia lyase, superoxide dismutase and catalase as compared to uncoated fruit. Chitosan was more effective than CMC in bringing these effects, and 0.5% was the most effective concentration. The results indicated that fruit coating by 0.5% chitosan and CMC maintained quality of chilli peppers by slowing physicochemical quality changes and improving the antioxidant system.

Abstract

Since 2015, the greatest harm to greenhouse vegetables in Kazakhstan has been caused by a previously unknown pest of nightshades – the South American tomato moth (Tuta absoluta) and the greenhouse whitefly (Trialeurodes vaporariorum). To obtain an environmentally friendly product, for the first time in Kazakhstan, the biological features of the predatory bug Macrolophus nubilus were studied and a complex integrated system was developed using biological methods. The data obtained on the survival rate and duration of development of M. nubilus larvae indicate that the eggs of the Sitotroga cerealella, as well as the eggs and larvae of the T. vaporariorum and T. absoluta, serve as a complete food for the predatory bug. Production tests of M. nubilus to assess the effect of temperature and photoperiod on the duration of larval development were carried out in the greenhouse complex “Naimbekov” on an area of 1 hectare (early indeterminate tomato hybrid Attia F1). The assessment of the biological effectiveness of M. nubilus against T. vaporariorum and T. absoluta was carried out in the greenhouse complex “Adelya” on an area of 5 hectares (mediumfruited carpal tomato hybrid Merlis F1) in southern Kazakhstan. These results contribute to more sustainable tomato production.
