One of the major diseases of rice paddy fields in Indonesia and the Asian countries is bacterial leaf blight or kresek caused by X. oryzae pv. oryzae (Xoo). Losses caused by the disease in Indonesia reached 70–80%, in India reached 74–81%, and Japan reached 20–50%, thus causing great losses in the economy. The objectives of that research were: 1) Characterize Xoo from Karesidenan Banyumas; 2) To study of the amount of damage and AUDPC (the area under disease progress curve) of bacterial leaf blight disease at Karesidenan Banyumas; 3) To obtain of Xoo pathotype by using the test varieties; 4) To obtaining genetic diversity of Xoo that found in Banjarnegara, Purbalingga, Banyumas, Cilacap dan Kebumen region. Research was carried out in several stages: isolation and characterization of Xoo from Barlingmascakeb region, testing of Xoo with five varieties testing, assesment of disease intensity of bacterial leaf blight and AUDPC in the field, and testing the genetic diversity of Xoo. The results showed that pathogen of bacterial blight on rice is Xoo characterized yellow colour of colonies on SPA medium, negative gram reaction, catalase positive, oxidase negative, negative growth at 0.1% TZC, negative starch hydrolisis , and resistance to 0.001% Cu(NO3)2 positive. Xoo pathotype isolats found in Banjarnegara was pathotype X, Cilacap were pathotype I and II and Purbalingga was pathotype II. Eighteen of Xoo from Karesidenan Banyumas (Banjarnegara, Purbalingga, Banyumas, Cilacap and Kebumen) of RAPD differ one from the others.

The purpose of this research was to know the correct soaking period of sawdust media and growth of red chili seedling. This research was conducted at the screen house of the Faculty of Agriculture, University of Jenderal Soedirman, Banyumas, from April-May 2019. The method used was Randomized Completely Block Design. The treatments were consisted of media containing soil, sawdust without soaking, sawdust that has been soaked for 1 day, sawdust that has been soaked for 2 days, sawdust that has been soaked for 3 days, sawdust soaked for 4 days, sawdust that has been soaked for 5 days, sawdust that has been soaked for 6 days, sawdust that has been soaked for 7 days. Observed variables included plant height 14 days, root length, number of leaves, leaf length, leaf width, plant height 42 days. The results showed that germination and growth of seedlings of chili plants on sawdust media that had been soaked for 7 days had better plant height, root length, number and length of leaves than on soil media.

<p><em>Storage</em><em> pest</em><em>s</em><em> </em><em>are one of many factors causing </em><em>damage</em><em> of</em><em> </em><em>storage commodities, </em><em>both quantitatively and qualitatively</em><em>.</em><em>  </em><em>T</em><em>his study </em><em>aimed</em><em> for </em><em>indentifiying insect storage pests of</em><em> rice, corn, and soybean in Batuwarno District</em><em>, Wonogiri Regency</em><em>. The  insect identification was conducted based on their morphological character (color, body shape, antennae, wing shape size, and number of tarsi). The commodity sampling in Batuwarno was taken by selecting the farmers in Sumberejo Village who have these three commodities. </em><em>4 of 12 farmers who had the three commodities (rice, cornm and soybean) in their storage were selected. </em><em> The method used in picking pest was by handpicking (directly). The sample was taken from five points, namely at the corner</em><em>s</em><em> and center diagonally in the </em><em>storage. R</em><em>esult</em><em>s showed that the insects were belong to</em><em> </em><em>Coleoptera</em><em> and Lepidoptera, namely Sitophilus oryzae, Sttotroga cerealella, Callosobruchus sp, Tribolium castaneum, Sitophilus zeamals, and Araecerus fasciculatus.</em><em></em></p>

Coffee berry borer (CBB) or Hypothenemus hampei Ferrari is a major insect pest on coffee crops in Indonesia. This pest could be controlled by using attractants that are placed in insect traps. The aim of this study was to examine the number of trapped CBB in alcohol-based attractants that were placed in the bottle traps. The experiment was conducted on coffee crops in polyculture system, during fruiting season (April-July 2019). Completely randomized design was used in this experiment. Three formulas of attractant used were methanol + ethanol mixture 1:1 (A1), methanol + ethanol mixture 3:1 (A2), and commercial product (A3). The attractants were placed in traps. The traps were laid randomly at poles or branches ca.160 cm in height and 2.0 x 2.0 metre apart. Result showed that the number of trapped CBB in traps that were filled with commercial formula (A3) was higher than the traps that were filled with other attractants (A1 and A2 formula). The number of trapped CBB was higher in traps that were placed near plants than the traps that were placed far from plants.
