Abstract

Root-knot nematodes (Meloidogyne spp.) have been reported to be one of the primary pathogens that decreased tomato production in Indonesia. Biological control of root-knot nematodes by using parasitic fungus as like as Paecilomyces lilacinus is still limited. An effective application of parasitic fungi could be successful by managing a suitability application time. The study aimed to determine the suitability of the application time of the P.lilacinus in controlling root-knot nematodes on tomato. The study was conducted in farmers' land that was infected by root-knot nematodes. The experiment was done in a randomized block design with applying P.lilacinus isolates on 12, 8, and 4 days before planting, planting time, and 4, 8, 12 days after planting. All treatments were repeated four times. The application of P. lilacinus onto tomato root at planting time was better at suppressing the development of root-knot nematode compared to applications made before or after planting. P. lilacinus was able to suppress the number of root-knot (66.08%), the number of egg groups (77.33%), the number of eggs (26.79%), and the number of nematodes in the soil (82.20%).

Abstract

Mahkota dewa [Phaleria macrocarpa (Scheff) Boerl] contains saponin that can be used as a botanical pesticide, including molluscicide. This study aimed to obtain the most effective storage time of leaf crude extract of mahkota dewa on the mortality of golden snail. The application was carried out in the greenhouse of Faculty of Agriculture of Universitas Andalas from March to May 2019. The study used a Randomized Block Design (RBD) consisting of time of storage, i.e., 0 day (2 hours), two days, four days, six days, and eight days those were applied to early-stage, late-stage, male and female of golden snail. The results showed that all storage time of mahkota dewa leaf crude extract had the same effect on early state golden snail mortality. However, at late state golden snail 0 day and two days, storage times were the best. Two days of storage time caused mortality of early-stage, late-stage, and male adult of the golden snail, however, 0 days (2 hours) for female adult.

Abstract

Meloidogyne spp. is one of the nematodes that cause root-knot on tomato plants. The botanical nematicide that potentially suppresses the nematode is castor bean leaves (Ricinus communis Linnaeus) extract. This research aimed to get the lethal concentration (LC50 and LC95) of castor bean leaves extract against nematode larvae in-vitro and their effect on the development of root-knot nematode (Meloidogyne spp.) in-planta on tomato plant. The research was carried out in Plant Pest and Disease Laboratory and Greenhouse of Agriculture Faculty, Universitas Andalas, using a completely randomized design (CRD) with two stages; in-vitro and in-planta. The research was used the experiment method in-vitro testing consists of six treatments and five replications, and in-planta testing consists of three treatments and nine replications. The result showed that the application of castor bean leaves extracts invitro can suppress Meloidogyne spp. larvae with LC50 by 0,27% and LC95 by 0,87%. The application of castor bean leaves extract in-planta with treatment concentration 2xLC95 (1,74%) showed effectiveness by 74,69% against the developments of Meloidogyne spp. on tomato plant roots.
