Abstract

Bacillus thuringiensis srv.toumanoffi is an indigenous endophytic rizobacteria from healthy soybean rizosphere capable of controlling bacterial pustule disease (Xanthomonas axonopodispvglycines). Rhizobacteria needs to be formulated to remain effective in storage and application. The aimed of this research was to obtain a stable bacterial formula in controlling bacterial pustule disease in soybeans. This research was designed in factorial in a randomized group consisting of 13 treatments with 3 replications. The Treatment was a combination of carrier material (peat, tapioca and coconut water+1% palm oil) and storage time (0, 2, 4, and 6 weeks). Soybean seeds were introduced with each Bacillus thuringiensis srv. toumanoffi formula before planting. The results showed that the formula Bacillus thuringiensissrv. toumanofi was relatively stable in suppressing the incidence and severity of bacterial pustule disease in soybean leaf. The best formula for controlling bacterial pustules was Bacillus thuringiensis srv. toumanoffi in peat, coconut water + palm oil and tapioca each 2 weeks storage.

Abstract

The Baramban Farmers Group, since 2014, has been carrying out healthy vegetable farming with vegetable products that have been certified Prima 3. However, until now, the management of healthy vegetable farming by the Baramban Farmers Group in Banuhampu District, Agam Regency has not experienced much development in farming because it has not created a broad market with prices that favor the welfare of farmers. Strengthening farmer institutions in marketing healthy vegetables is thus very important and have become an essential element in developing healthy vegetable agribusiness in local, national, and even global markets. The method used is counseling, coaching and mentoring. This service activity is planned to be carried out over the next five years, starting with building a cooperation agreement with the Baramban farmer group starting in 2020. Several alternative solutions to solve the problems of healthy vegetable farmer group partners proposed and agreed upon by the Baramban Farmer Group are: a. Carry out mentoring activities for healthy vegetable farmers by transferring resources from universities through integrated science an agribusiness perspective, b, empowering farmers based on group institutional strengthening to build collective action that is independent of farmers to drive healthy vegetable markets, c. Facilitate farmers to create healthy vegetable market segments through modern markets and online markets with information technology 4.0 and 4. Building partnerships with Transmart as a modern market on a national scale and has a global-scale marketing network. The conclusion is that farmer groups are willing to become partners of the Community Service Team in a community partnership program scheme to help businesses develop.

Abstract

The functional response of the parasitoid Eriborus argenteopilosus (Cameron) (Hymenoptera: Ichneumonidae) were studied using Crocidolomia pavonana (Fabricius) (Lepidoptera: Pyralidae) larvae as host at different densities. All larvae were exposed to one E. argenteopilosus female for three hours at three different temperatures, i.e 20 oC, 25 oC, and 30 oC. Data were analyzed using logistic regression to determine the type of functional response. At 20 oC E. argenteopilosus showed type II functional response, while at 25 oC and 30 oC the functional response is type III. Based on surface analysis, the optimal parasitism rate occurred at 22.24 oC with 10.12 larvae parasitized/hour. The larvae density to achieve optimal parasitism rate was 69.38 larvae. The optimal oviposition rate was 12.59 eggs/hour which occurred at 24.41 oC, using a density of 94.54 larvae.

Abstract

Yellow leaf curl disease of pepper has become an emerging important disease in West Sumatra since early 2000. Several attempts have been made, including disease survey and detection, in order to identify the causal agent of the disease. Pepper (Capsicum annuum) plants showing yellow leaf curl from West Sumatra were analyzed for presence of Begomovirus employing Polymerase Chain Reaction (PCR) with degenerate primers pAL1v 1978 and pARc 715. A DNA fragment of 1.6 kb was successfully amplified and subjected to direct sequencing. A stem loop region was found in the nucleotide sequence obtained, which contains the conserved nucleotide signature sequence TAATATTAC present in begomoviruses. Based on the stem loop region comparisons and phylogenetic analysis, the virus isolates from West Sumatra showed the closest relationship to Pepper yellow leaf curl Indonesia virus (PYLVIV) and Tomato yellow leaf curl Indonesia virus (TYLCIV). The sequence was different from other Asia Begomoviruses reported earlier. These isolates were divided into three groups which were tentatively called Pepper yellow leaf curl Indonesia virus-West Sumatra-[group 1], -[group 2] and -[group 3] {PYLCIV-WS-[group1], -[group2], and -[group3]}.

Abstract

During the last three years, several snails as pests that attacked vegetables, especially cabbages (Brassicaceae) in the highland vegetable crop center of Mount Marapi, were found to cause damage. This study aimed to obtain the species, population, and attack rate of snails pests on the cabbage plants. The study was conducted using a survey method with purposive sampling conducted from July to September 2019 with the criteria of observing plants two weeks after planting and determining the sample diagonally. The results showed that cabbage plants in Mount Marapi, Agam Regency, were attacked by two snails, namely Bradybaena similaris and Parmarion sp. The population of B. similaris was higher than that of Parmarion sp. Mustard plants are most at risk of being attacked by snails, with the highest percentage and intensity of attack even though the damage category is classified as moderate. Mustard plants are also among the first time to be attacked by snails. Cultivation techniques affect the density and attack rate of pest snails at the research site. Key words: Slug attack level, species and population density, Bradybaena similaris, Parmarion sp.
