Abstract

The tomato plant (Lycopersicum esculentum Mill.) is one of the horticultural crops that is frequently cultivated and consumed due to its considerable nutritional value, including vitamins A and C. In the cultivation process, farmers often face problems caused by plant pests, one of which is Thrips (Thrips palmi Karny). This study aims to determine the effectiveness of insecticides containing the active ingredients spirotetramat + abamectin at several concentrations against T. palmi. Research activities were conducted in Pujon District, Malang Regency, and Junrejo District, Batu City, East Java, from April to June 2023. The research used a Randomized Complete Block Design (RCBD) with 5 treatments: spirotetramat + abamectin 1.00 ml/l; 0.75 ml/l; 0.50 ml/l; 0.25 ml/l; and a control. The results showed that the use of spirotetramat + abamectin insecticides at different concentrations affected the average T. palmi population level and yield in tomato plants. Treatment with a concentration of 1.00 ml/l was the most effective, achieving an efficacy index (EI) value of more than 70%.

Abstract

Coleopteran has a remarkable degree of environmental adaptation, allowing it to survive and reproduce in a variety of habitats. Research was conducted to determine the distribution of Coleopteran insects and the influence of commodities on the composition of Coleopteran insects. The research was conducted in May-August 2021 in Pendem Village, Batu City. Sampling is accomplished visually and through the placement of yellow pan traps and pitfall traps on tomatoes, large chili peppers, onions and cucumbers for 9 weeks. The study revealed 15 morphospecies belonging to the families Anthicidae, Carabidae, Chrysomelidae, Coccinellidae, Scarabaeidae, Staphylinidae, and Tenebrionidae which have roles as herbivore, predator and detritivore. In tomato plants 862 individuals were found, in large chili plants 1444 individuals were found, in onions plants 519 individuals were found and in cucumber plants, 697 individuals were found.

Abstract

Soil is a habitat for many types of microbes that have a role in maintaining soil nutrition, and most of them grow around plant roots. Factors that are quite influential in the growth process are the hormone auxin, which has a role in stem bending and stimulates differentiation. This study aimed to obtain a genus of IAA hormone-producing rhizosphere fungi (Indole-3-Acetic Acid) and determine the effect of environmentally friendly and conventional land cultivation on the diversity of IAA hormone-producing fungi at Agrotechnopark UB Cangar Garden. Fungi isolates were cultured on Potato Dextrose Agar (PDA) and Potato Dextrose Broth (PDB) media enriched with tryptophan as a precursor to form IAA. IAA measurements were carried out qualitatively by adding the Salkowski reagent and quantitatively by measuring the absorbance. As many as 10 rhizosphere fungal isolates were obtained from environmentally friendly land and 8 fungal isolates from conventional land, which produced IAA hormones. The fungal genera obtained included Acremonium, Aspergillus, Colletotrichum, Fusarium, Penicillium, and Trichoderma. Environmentally friendly cabbage fields (average: 283.8 ppm) showed higher yields than conventional fields (average: 140.9 ppm) in producing IAA hormones. There was a correlation between soil pH and organic matter on fungal diversity, with a correlation value of 0.878. The diversity index value of rhizosphere fungi was 1.359; the evenness index was 0.845, and the dominance index was 0.302 on environmentally friendly land. The diversity index value of rhizosphere fungi was 1.213; the evenness index was 0.875, and the dominance index was 0.344 on conventional land.
