Abstract

Tomato plants (L. esculentum Mill.) are vegetable crops. Tomato production in South Kalimantan is very low due to the attack of a plant disease, namely the yellow curly virus. Caused by the presence of the vector B. tabaci, control usually carried out by farmers is only controlling the vector with insecticides, not to control the virus. This control has negative impacts. Good control and has been widely used is biological control. Which utilizes microorganisms in tomato plants to induce resistance to yellow curly virus infection. In this study, a completely randomized design (CRD) was designed with one factor. The administration of Bacillus spp. derived from bamboo plant roots, elephant grass roots and chili roots was the factor tested. There were 5 treatments and 4 replications, The results of this study showed that the administration of Bacillus spp. derived from bamboo plant roots, elephant grass roots and chili roots, was able to induce tomato plant resistance to yellow curly virus infection. The lowest percentage of yellow curly virus attack intensity with an average (10.54%) was the tomato plants treated with Bacillus spp. derived from elephant grass roots. The average attack intensity of yellow curly virus on untreated and inoculated plants was 32.63%. The administration of Bacillus spp. from bamboo roots (T2), elephant grass roots (T3), and chili roots (T4) was shown to induce tomato plant resistance to yellow curly virus infection.

Abstract

A monophage herbivorous insect called S. pectinicornis can be utilized to biologically control the weed Pistia stratiotes. Insect mass reproduction followed by release into the target weed area is one technique that can be used. The quality of the feed must be taken into consideration during maintenance in order to increase the fitness of S. pectinicornis insects and enable them to function at their best. The fertilization procedure can improve the nutritional value of P. stratiotes as a feed source. The experiment involved applying NPK fertilizer to P. stratiotes at 6 different levels: 0 g (control); 5 g; 10 g; 15 g; 20 g; and 25 g. The findings demonstrated that when NPK fertilizer was applied to Pistia stratiotes, S. pectiniconis larvae, pupae, and imago had a better chance of surviving than controls. S. pectinicornis showed improved insect growth and development since its lifespan was shorter than controls at every developmental stage. The ideal NPK fertilizer dose for maintaining Pistia stratiotes as feed during S. pectinicornis propagation is 15g/20 L of water.
