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%). Keywords: Application time, Meloidogyne spp., Paecilomyces lilacinus, tomato

Papaya leaf (Carica papaya Linnaeus) is one of the sources of botanical fungicides that is known to have an ability in inhibiting Colletotrichum gloeosporioides growth. The aim of the study was to determine the effectiveness of papaya leaves extract to suppress of C. gloeosporioides growth that caused anthracnose disease of red pepper (Capsicum annuum Linnaeus) in vitro assay. The study was done in a Completely Randomized Design (CRD) with five concentration levels of papaya leaves extract and control (1%, 2%, 3%, 4%, 5%, and control). The parameters were colony growth, colony area, wet weight, dry weight, and conidia number (per ml of suspension). The data obtained were analyzed by ANOVA and LSD tests at 5% significance level. The results showed that the application of papaya leaves extract with different concentrations could suppress the growth of C. gloeosporioides, the pathogen of anthracnose disease in chili. The higher the concentration of papaya leaves extract given, the higher its effectiveness in suppressing the growth of C. gloeosporioides. Application at the 5% concentration was the most effective inhibiting the conidia formation (82.5%), followed by inhibiting the expansion of the colony (64.04%), reducing wet weight (45.16%) and dry weight (54.16%). Keywords: Anthracnose, botanical fungicides, Capsicum annuum, concentration, growth inhibitor

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. Keywords: Mahkota dewa, golden snail, storage time

Camel groundbeetle (Ophionea nigrofasciata Schmidt-Goble 1846) or CGB is reported as one of predators of brown planthopper (Nilaparvata lugens Stal 1854) or BPH. The difference in BPH densities is assumed to affect the predation rate of the CGB. This study aimed to determine the predation rate of CGB on BPH at different densities. This experiment used a completely randomized design (CRD) consisting of six treatments and five replications. The treatment consisted of predation of one CGB at several BPH densities (5, 10, 20, 30, 40, and 50 individuals). BPH used was second-third instar of nymphs, and the CGB used was female. The results showed that the predation rate of CGB increased with increasing BPH density with functional response types classified as type I (Linear). The highest predation occurred at 50 density (23.6 individuals or 47.2% of BPH provided). The difference in density of BPH did not affect the bodyweight gain of CGB and tended to decrease due to different prey-seeking behavior. Keywords: Nillaparvata lugens, Ophionea nigrofasciata, predation, predator

Crocidolomia pavonana Fabricius is an important pest in the Brassicaceae family that can cause up to 10% -100% yield losses. One of the plants that are considered as potential botanical insecticides is Kabau Plant (Archidendron microcarpum (Benth.). This study was aimed to determine the ability of kabau pell crude extract to control C.pavonana. The study was conducted at Rejang Lebong State Community Academy Campus and Natural Resources Organic Laboratory of Faculty of Mathematics and Natural Sciences, Universitas Andalas, from September 2016 to February 2017. The research was conducted in three stages: filter, bioactivity, and chemical profile examination. The results showed that the kabau peel crude extract was classified as an active insecticide for C.pavonana. At a concentration of 0.5%, kabau peel crude extract caused larval mortality to reach 63.33% in the filter test and 70% in the bioactivity test. The extract consisted of phenolic compounds, saponins, flavonoids, steroids, terpenoids, and alkaloids. Keywords: Kabau plant, secondary metabolite, botanical insecticide, Crocidolomi pavonana

Fall armyworm or Spodoptera frugiperda (J.E Smith) is a significant economic pest of maize. S. frugiperda is reported for the first time to attack and damage the corn in Indonesia since 2019. The study was aimed to find the effectivity of chlorantraniliprole to control the larvae of S. frugiperda on maize. The study was divided into two steps, in the laboratory and the field. The laboratory treatment was application of chlorantraniliprole 2 cc/l, Metarhizium anisopliae (10? conidia/ml), and Beauveria bassiana (10? conidia/ml) that applied onto the leaf, larvae, and leaf + larvae with five replications for each treatment. The field test used three treatments i.e., chlorantraniliprole field, farmer field, and control with three replications for each treatment. The research showed that chlorantraniliprole at a dose of 2 cc/l had the highest mortality of S. frugiperda with 100% mortality on average during five days after application. However, the application of M. anisopliae and B. bassiana did not affect the mortality of S. frugiperda for 3 days after application. There was no difference in mortality when chlorantraniliprole applied onto leaf, larvae and leaf + larvae. Application of chlorantraniliprole in the field at a dose of 2 cc/l at 1, 3, and 5 weeks after planting was effective to control S. frugiperda on maize. Keywords: Chlorantraniliprole, entomopatogenic fungi, fall armywarm
