Background: Pod borer, Maruca testulalis is one of the harmful mung bean pests and cause substantial damage to the crop or failure to harvest. This study was carried out to identify the level of resistance to pod borer of mungbean accessions. Methods: Field research was conducted at Muneng Experimental Farm, Probolinggo, East Java, Indonesia in the 2018 dry season using the randomized block design and repeated two times. A total of 50 accessions of mungbeans were planted in two growing environments, namely: L1 = controlled environment (Maruca pest was controlled with NPV biopesticide 2 g/liter of water) and L2 = uncontrolled environment (Maruca pest was not controlled with any kind of pesticide). Observations were made on the intensity of borer attack and dry seed weight. Result: Eleven accessions gave a low resistant (LR) to moderately resistant (MR) categories responses against M. testulalis attacks. The pod damage from the eleven selected accessions was less than 15% under environmental conditions without control (L2). Control application (L1) reduced pod damage by 48.5% and increased mung bean seed yield by 25%, compared to without control (L2). The eleven accessions that were consistent or stable with low attack intensity under conditions with and without control gave dry seed weights above average, except for accessions (MLGV 0054, MLGV 0115 and MLGV 0320) which had dry seed weights lower than the average both in the growing environment with control (L1) or without control (L2).

[THE INCIDENCE OF POD-BORER, Maruca testulalis Geyer (Lepidoptera: Pyralidae) IN EIGHT MUNG BEAN VARIETIES (Vigna radiata L.) AND ITS EFFECT ON YIELD]. Mung beans are an essential food crop in Indonesia, whose production is still increasing to meet domestic needs. However, the high attack of plant pests Maruca testulalis Geyer (Lepidoptera: Pyralidae) is one of the leading causes of the low production of green beans. The use of superior varieties is one solution to controlling these pests. This study was conducted to test seven superior varieties of green beans, namely Vima 1, Vima 2, Vima 3, Murai, Kenari, Kutilang and Seriti and one local variety against M. testulalis. The study used a completely randomized block design and was repeated three times. The results showed that the mungbean varieties Vima 1, Vima 2, and Vima 3 had M. testulalis attack with the lowest level of seed damage in sequence, namely 5.84%, 7.94%, and 6.39%. Even though the percentage of pod borers attack did not significantly affect the growth of all Balitkabi superior varieties and one local variety of mungbean planted, the Kutilang variety was the highest yield with seed yield rates that were as low as other low-attack varieties.

Background: Gram pod borer, Helicoverpa armigera (Hubner) and spotted pod borer, Maruca testulalis (Geyer) are important pod boring insects infesting the greengram, [Vigna radiata (L.) Wilczek] throughout the India. A number of synthetic insecticides are known to be effective against these borers but most of them have been phased out as a result of high toxicity to the pollinators and other biotic fauna, therefore, a group of new chemical insecticides with biopesticides have been tested for bioefficacy against these insect pests. Method: A field experiment was conducted at S.K.N. College of Agriculture, Jobner, Rajasthan during kharif, 2018 in randomized block design (RBD) with 9 treatments and 3 replications. The observations were recorded of Helicoverpa armigera (Hubner) and spotted pod borer, Maruca testulalis (Geyer) borers one day before and 1, 3, 7 and 15 days after application of insecticides and biopesticides in each the spray from ten randomly selected and tagged plants/ plot. From the data recorded per cent reduction in population over control was calculated. The per cent pod damage was calculated by counting damaged pods out of healthy pods of greengram. Result: The spinosad 45 SC (0.01%) proved to be most effective, indoxacarb 14.5 SC (0.01%) followed by fipronil 5 SC (0.01%), whereas, treatments of neem leaf extract (10.00%), Beauveria bassiana 1.15 WP 1X108 spore/ l proved to be least effective. The maximum seed yield of 9.13 q ha–1 was obtained in the plots treated with spinosad 45 SC (0.01%) followed by indoxacarb 14.5 SC (0.01%) (8.89 q ha-1), fipronil 5 SC (0.01%) (8.60 q ha-1).

Resistance of some groundnut cultivars to soybean pod borer, Etiella zinckenella Treit. (Lepidoptera: Pyralidae).  Five groundnut cultivars: Badak, Panther, Sima, Gajah, and Simpai, were grown in field in June-August, 2006 to determine their resistance/susceptibility to Etiella zinckenella Treit.  Two local cultivars (big and small seeds) were included as comparison (controls). All cultivars were grown in experimental plots arranged in a randomized complete block design (RCBD), replicated three times. The incidence of soybean pod borer and damaged pods were observed at 9, 11, 13 weeks after sowing (WAS) at 10 sample plants taken randomly from each plot. All cultivars were harvested at 13 WAS. Number of damaged pods was counted and percentages per plant were calculated. Larvae observed inside pod or in the soil were counted and collected. The seed yield per plant and weight of 100 seeds from 100 sample plants taken randomly at harvest were weighted to nearest gram at 10% water content. Pod toughness (hardness) was measured with penetrometer. Resistance level of each cultivar was determined based on cultivar’s means and overall mean and standard deviation of the percentages of damaged pods. Data were analyzed with analysis of variance (ANOVA) and means were separated with DMRT. The result revealed that mean percentages of damaged pod differed significantly between cultivars. Seed yield of cultivar Panther, Sima and Badak were significantly higher than those of the other two and local cultivars. Cultivar Panther was categorized as resistant, cultivar Sima and Badak as moderately resistant, while the others as susceptible. The relative resistance of groundnut cultivar seems, at least in part, to correlate with the structural hardness of pod.

<p>Two experiments to study responses of resistance of maize germplasm to downy mildew (Peronosclerospora philipinensis) have been conducted. Both experiments were arranged in randomized block design with two replication. The treatments in each experiment (2014 and 2016) were 70 maize accessions. The accessions were planted in planting distant of 75 cm × 20 cm, in 5 m rows, resulting in 20 plants per row. In every 10 rows, two check varieties were planted, i.e. one susceptible and one resistant variety. Ten days prior to planting, the soil was fertilized with mixed fertilizers consisted of urea, ZA, SP36, and KCl at a dose of 100, 100, 100, and 100 kg/ha, respectively. Fertilization II and III was given at 30 days after planting, and 45 days after planting with a dose of 100 kg urea/ha. As a source of inoculum downy mildew, around the repeated plot was planted with varieties Anoman variety (susceptible variety) that was inoculated with a suspension of downy mildew pathogen. Observation was conducted at 25, 35, and 55 days after planting, with the standard score of resistant to downy mildew, followed: 0–10% = resistant, 11–25% = moderately resistant, 26–50% = moderately susceptible, &gt;50% = susceptible. The result of the experiments showed that there were 5 accessions resistant to downy mildew (P. philipinensis), i.e. CML 440×MR4-9-30-3, 664, 60, 572, and 554 with the intensity of downy mildew infection ranged from 5 to 10%. Twelve other accessions were classified as moderately resistant, i.e. CML 440×MR4-9-98-2, 440×MR4-9-98-4 CML, CML 440×MR4-9-124-1, 66, 71, 319, 108, 73, 48, 105, 554, and 682 with intensity of infection ranged from 13 to 25%. At the same experiments, the average intensity of downy mildew infection on susceptible check varieties reached 100 percent.</p>

ABSTRACTResistance Test of Potato Clones Derived from Crossing of Atlantic x Repita to Late Blight (Phytophthora infestans)Late blight, incited by Phytophthora infestans is the most destructive disease of potato. The management that is effective and environmentally-friendly is the use of resistant variety. The objective of this study was to test the resistance of the six potato clones (AR 04, AR 05, AR 06, AR 07, AR 08 and AR 09) derived from crossing var. Atlantic x var. Repita to late blight caused by P. infestans. Var. Atlantic, Repita and Granola were used as susceptible, resistant and susceptible but the most-grown variety, respectively. Field test was located in Ciwidey, one of the potato growing center where late blight is endemic since potatoes are continuously grown. The treatments were arranged in a randomized block design with 3 replicates. The result showed that clones AR 07 and AR 08 were more resistant than the other potato clones, but it still below the resistance level var. Repita. However, based on statistical test on the diseases development (AUDPC), clone AR 08 could be categorized as resistant, equal with of the resistance level of var. Repita.Keywords: Potato clones, Rsistance, P. infestansABSTRAKPenyakit hawar daun yang disebabkan Phytopthora infestans merupakan penyakit utama pada tanaman kentang.

There are many of rice field which is located near the industrial area. The industrial waste contains heavy metals (chromium) which will cause contamination of rice if the waste isn’t treated properly. The used of chemical fertilizers can cause chromium contamination. It needs an effort to do remediation, such as using phytostabilization mechanism. This research aimed to determine the role of chelator in chromium phytostabilization and its influence on the growth and quality of rice. The study was conducted in Waru village, Karanganyar in May to October 2018.  This research was factorial design used completely randomized block design with two factors, namely chemical fertilizers and chelator (<em>Agrobacterium </em>sp. I<sub>26</sub>, and manure). The parameters observed are chromium content and uptake by plant tissues (roots, shoot and rice), plant height and a number of clumps. Research output was without chemical fertilizer-chelator <em>Agrobacterium </em>sp. I<sub>26</sub> that can increase the chromium uptake in roots as big as 95.38 %, increased up to 10 %  in the shoot and decreased up to 92.38 % in rice compared to control. Application of <em>Agrobacterium</em> sp. I<sub>26</sub> can be recommended to produce good quality and quantity of rice (good growth and free from harmful pollutants such as chromium metal).

The Effect of Organic and Inorganic Fertilizers on The Growth and Results of Green Mustard (Brassica rapa L.). Green mustard (Brassica rapa L.) is a vegetable that preferred by many consumers, this causes many farmers cultivate this vegetables. One of the important factor in the cultivation of green mustard is fertilizer type. Alternative to improve soil quality and fertility is by providing organic matter. A field research was conducted to evaluate the effect of organic and inorganic fertilizers on the growth and yield of green mustard, in Banjar Taman Tande, Baturiti Village, Bedugul from April to June 2018. This study was designed with a Randomized Block Design with nested patterns consisting of two factors. The first factor was the type of fertilizer, which was consisted of four types of organic fertilizer, namely: vermicompost, cow manure, chicken manure, goat manure and inorganic fertilizers (NPK Mutiara). The second factor was fertilizer dosage, which was consisted of three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha, while for NPK Mutiara fertilizer dosages, namely: 0 kg/ha, 150 kg/ha, and 300 kg/ha.The results showed that the effect of organic and inorganic fertilizers were not significantly different on the growth and yield of green mustard plants and RAE values. The total N content of soil on vermicompost treatment was 0.23% equal to NPK Mutiara. The total population of soil microbes on vermicompost treatment under dosage of 15 tons/ha and 30 tons/ha were 1.4 x 106 cfu/g that was much higher compared to NPK Mutiara 150 kg/ha fertilizer (0.3 x 106 cfu/g).

A field experiment on evaluation of biopesticides against gram pod borer (Helicoverpa armigera Hub.) on pigeon pea was carried out during kharif season of 2012-13. The experiment was laid out in randomized block design with three replications. Gram pod borer is a major pest of pigeon pea in India. For the management of this pest seven biopesticides were tested along with control. Among the biopesticides, Beauveria bassiana @ 1 liter / ha (1x1012 spores/ml) was found to be most effective biopesticide as it recorded lowest larval population (6.68 larvae / 5plants). The highest larval population was recorded in control (12.61 larvae /5 plants). The least effective treatment was Paecilomyces fumosoreseus (9.31 larvae /5 plants). Similar trend was observed in the grain yield as 1667.55 kg/ha, 709.41kg/ha and 1025.21kg/ha , respectively.
