The main disease in maize is downy mildew caused by the fungus Peronosclerospora spp.. This pathogen can cause yield losses of up to 100%. Therefore, efforts to control this disease are continuously carried out, including technical culture, assembly of resistant plants, and use of synthetic fungicides. At the farm level, the use of metalaxyl, synthetic fungicides is the most common practice. On the other hand, it has been reported that some Peronosclerospora groups are starting to become resistant to metalaxyl. These problems lead to the need for alternative controls, for example with biological agents. Biological agents from bacterial groups have been developed to control plant disease, but for downy mildew is still limited. The purpose of this study is to screen and test Bacillus spp. ability to suppress downy mildew and promote the growth of maize. The assay was carried out on seeds by invitro to investigate growth-promoting reactions and also testing under controlled conditions in greenhouses to investigate the suppression ability of downy mildew disease development. The results showed B. polymyxa strain BP18, Bacillus subtilis strain BS41, Bacillus sp. strain BT1, and Bacillus sp. strains can stimulate the growth of corn seedlings and suppress downy mildew. The best isolate in suppressing downy mildew was Bacillus sp. strain BT1 with the smallest AUDPC value (3.94) and the highest protection index (82.71%). It is hoped that these results will find potential isolates and have the potential to be developed into biopesticides and biofertilizers.

Kemampuan tanaman untuk tumbuh normal pada kondisi tercekam kekeringan disebut sebagai daya adaptasi. Salah satu teknologi budidaya yang dapat diterapkan untuk meningkatkan daya adaptasinya pada kondisi tercekam kekeringan adalah dengan penyemprotan osmolit pada daun tanaman. Tujuan dari penelitian ini adalah untuk mengetahui respon pertumbuhan dan produksi tanaman kacang hijau akibat pemberian osmolit sorbitol pada intensitas cekaman kekeringan yang berbeda. Penelitian dilakukan di dalam rumah kaca dengan menggunakan RAL faktorial yang terdiri dari 2 faktor, yaitu konsentrasi sorbitol dengan 4 taraf (0,10,20, dan 30 ml/l) dan intensitas cekaman kekeringan dengan 4 taraf (tidak tercekam, tercekam kekeringan mulai stadia vegetatif, pembungaan, dan pengisian polong sampai panen). Hasil penelitian menunjukkan pemberian osmolit sorbitol 10, 20, dan 30 ml/l belum mampu meningkatkan produksi kacang hijau pada kondisi tercekam kekeringan seperti tanaman yang dibudidayakan pada kondisi normal (tidak tercekam kekeringan), namun untuk mendapatkan hasil aplikasi osmolit sorbitol yang efesien yaitu dengan menggunakan konsentrasi 30 ml/l yang dilakukan pada tanaman yang mendapat cekaman kekeringan paling lama yaitu mulai stadia vegetatif.

The study on responses of Helicoverpa armigera Hbn. to sublethal HaNPV (H. armigera nuclear polyhedrosis virus) infection was carried out in the laboratory. The reproduction rate was scrutinized as their impact of HaNPVs exposures. Fifth instar of H. armigera larval was orally infected on sublethal serial dilution of HaNPV (1,800; 180; 18; 1.8; 0.18; 0.018 ppm from stock concentration of 1.1 X 10^9 PIB per ml suspension). A significantly female pupal weight forms the response of H. armigera to sublethal HaNPV infection on the concentration tested. However larval period, male pupal weight, pupal period, oviposition period, life span of imago, fecundity, fertility and survival did not significantly form the response of H. armigera to sublethal HaNPV infection. All treatment showed lower reproduction rate compared to the untreated, especially reproduction rate based on either debilitating effect and mortality or just based on debilitating effect.

One of the obstacles to melon cultivation is the availability of seeds and the high price of melon seeds. This condition causes the need to assemble superior melon varieties with the expected characters. This study aims to form a pure line of melon with certain superior characteristics and can be proposed as a new high-yielding variety in the open-pollinated category. The research was conducted at the Experimental Garden of the Agrotechnology Study Program, Faculty of Agriculture, Trunojoyo University, Madura, from September-December 2022. This study used a randomized block design method. The treatments used were nine pure lines of melon (PK-669, D-162, PK-361, PK-165, PK-114, D-029, D-5089, PK-211, and comparison). Each treatment was repeated three times, and each experimental unit consisted of 12 plants. Research data were analyzed using analysis of variance (ANOVA) and HSD test α = 0.05. The selection advancement was analyzed by comparing character data for each generation. The research showed that the results of the characterization of ten melon lines S0-S4 generation on the characters of fruit length, fruit diameter, flesh thickness, and melon fruit weight showed a decreasing trend in each generation. The S4 generation (9.17 °brix) in the character of the average sugar content there was an increase that was not significantly different from the S3 generation (9.03 °brix), while the number of seeds in each generation had an average value that was not significantly different but occurred an increase in the number of seeds in the S3 (372) and S4 (381) generations. An increase in one generation of the population in the linear regression equation is estimated to reduce the character of fruit length by 0.50 cm, fruit diameter by 0.465 cm, flesh thickness by 0.140 cm, fruit weight by 0.199 Kg, sugar content by 0.752 °brix, and a number of seeds by 5.4.
