Abstract

The observation of the  control of bio-diversity the main pest Empoasca on tea plantation effective, efficient and neighborly environment has been undertaken testing insects glue as biodiversity control to main pests Empoasca in the field. The research done in the Pasir Sarongge Experimental Garden (1.100 m asl), Cianjur, West Java. Testing designed in random block design (RBD) with 5 treatment and 5 replication. Treatment tested were: (1) formulation of glue M-5; (2) formulation of glue M-10; (3) formu­lation of glue M-15; (4) formulation of glue comparator; (5) untreated. All the treatment of glue was applied by means of smeared on mineral water bottle (600 ml), every plot installed 5 bottle. Parameters in the observations were the population Empoasca trapped in glue, and intensity attack Empoasca. Research results in a laboratory pointed out that glue M-5 more effectively entraps pests Empoasca when compared to another formu­lation, and comparator glua, as well untreated. Whereas the results of observation in the overall pointed out that the use of formulation of glue M-5 which is formulation lowest have enough effectively to catch pests Empoasca in the field was 19,83 head trap or the equivalent to the 79,32 head any every plot in the area plot 50 m2. The arrest shall taller when experiments was undertaken in dry season.

Abstract

Empoasca (Empoasca flavescens) is a major pest of tea plant in almost all elevations and can lead of lost production more than 40%.  Chemical insecticide is still use to control this pest. In a long term, this  could be increase the cost as well as environmental damage. To support an environmentally sound control method, an experiment has been conducted by using active ingredient of surawung langit leaf extract and using of mass controlling tool. The experiment was carried out at a productive tea plant of two years prunning, clone GMB-7, block B4, Pasir Sarongge Experimental Garden, Cianjur.   The experiment was arra­nged in a factorial randomized block design with eight treatments, and replicated three times. The aim the experiment was to evaluate the effectiveness of botanical insect glue surawing langit (salvinia hyspanica) and mass controlling application technique on empoasca in tea plant. Result showed that botanical insect glue surawing langit at 10 and 20% applied using mass controlling tool with two blowers were effective in catching of Empoasca as swell as its attack intensity and shoot production.

Abstract

An experiment to find out the effectiveness of formulation of brenuk botanical insecticide on Empoasca flavescens on tea was carried out at Pasir Sarongge Experimental Garden, Research Institute for Tea and Cinchona, from Juni up to September 2012. The experiment was designed in randomized complete block design with eight treatments and three replications. The treatment was consist of: (1) brenuk insecticide at 0,5 litre of EC formulation/ha, (2) brenuk insecticide at 1,0 litre of EC formulation/ha, (3) brenuk insecticide at 1,5 litre of EC formulation/ha, (4) brenuk insecticide at 0,5 litre of WP formulation/ha, (5) brenuk insecticide at 1,0 litre of WP formulation/ha, (6) brenuk insecticide at 1,5 litre of WP formulation/ha, (7) marigold insecticide at 1,5 litre of EC formulation/ha, and (8) control. The water spray volume used was 300 litre/ha. The observation parameters were the attack intensity of E. flavescens, the population of E. flavescens on the production of tea shoots. The experiment result indicated that the application of brenuk insecticide at 0,5 litre/ha in EC as well as WP formulations were efective in the decreasing of attack intensity of E. flavescens, as well as the population of Empoasca to the extend of 69,99% and 63,63% respectively. Indirectly, these treatments could increase the shoot production of tea plant.

Abstract

A research to know the effectiveness of formulation of botanical insecticide marigold (Tithonia diversifolia) on E. flavescens has been carried out at a green house of Research Institute for Tea and Cinchona (RITC), as well as at Pasir Sarongge Experimental Garden of RITC, Cianjur, West Java, from September up to November 2011. At both experimental sites, the experimentations was designed in a randomized complete block (RCB) with  six treatments, replicated four times. Treatments tested were formulation of marigold extract 10% and 15%, each at doses of 0.5 and 1.0 l/ha, standard chemical insecticide, and control. All treatments were applied by spraying, using one litre-hand sprayer at green house, and using knapsack sprayer with spraying volume 300 l/ha in feld. At green house, parameter observed was mortality of E. flavescens. Mortality at formulation of marigold extract 15% (92%, in average) was higher than at formulation of marigold extract 10% (76%, in average) while in field were attack intensity of E. flavescens, tea shoot production, and phytotoxicity. Results showed that at green house, formulation of marigold extract 10% and 15% at doses of 0.5 dan 1.0 l/ha were effective to result in high mortality of E. flavescens. While in field the formulations at both doses were effective to suppress attack intensity of E. flavescens. However, the effectiveness of 1.0 l/ha doses was higher than 0.5 l/ha doses, which comparable with standard chemical insectiside treatment. The formulations at both doses indirectly also could increase shoot production, and did not cause phytotoxicity  on tea leaves/shoots.

Abstract

A research experiment to know the effect of pottasium on the population development of scarlet mite and growth of young tea was carried out. The experiment was conducted at Green House of Plant Protection Department Research Institute Tea and Cinchona Gam­bung, Bandung, West Java, from December 2011 until July 2012. The soil type used is Andisol and altitude is 1.250 m above sea level. The treatments were potassium fertilizer appli­cations of 0, 30, 40 (standars treatment), 50, 60, 70, 80, 90, and 100 kg K20/ha/year; in which the 0 dosage was used as untreated control. The result of the experiment showed that: pottasium fertilizer at the dosage 70 kg K2O/ha/year to 100 kg K2O/ha/year reasonably effective in pressuring the development of the population development of scarlet mite and increasing the number of leaves as indication of rising class seedlings on young tea. Pottasium fertilizer at the medium dosage 70 kg K2O/ha­/year reasonably effective in pressuring the development of the population development of scarlet mite and increasing the number of leaves as indication of rising class seedlings, when compared to the standards (40 kg/ha/y) and control dose on young tea.

Abstract

The objective of this research was to study the interaction effect between the number of physiologically mature maintenance leaves on tipping and the frequency of application foliar fertilizer application on the development of the main pest Empoasca, weeds and the yield of GMB 7 tea clone. The experiment was con­ducted at Gambung Estate, block A4, Re­search Institute Tea and Cinchona, Mekarsari Village, Pasirjambu Subdistrict, Bandung Regency, with altitude  about  1.300 m above sea level. The average rainfall was 3.035 mm/year and the type of rainfall is B according to Schmidt and Fergusson (1951). The soil type is Andisol with pH 5,9. The experiment was done from Decem­ber 2011 until July 2012. The experiment has factorial Randomized Block Design (RBD) with three replications. The first factor is physio­logically mature maintenance leaves on tipping (A) with 3 treatments: a0 = 3 leaves, a1 = 5 leaves and a2 = 7 leaves. The second factor is the application of follar fertilizer (B) with three treatments: b0 = without application, b1 = one application and b2 = two applications. The result showed that no interaction between the number of physiologically mature maintenance leaves and the frequency of foliar fertilizer application on the attack intensity of Empoasca. The interaction between five physiologically mature maintenance leaves and one application of folliar fertilizer treatment were effective to control pest and weeds. The interaction hap­pened between the number of physiologically mature maintenance leaves on tipping and the frequency application of foliar fertilizer on yield at 10 and 12 weeks after determined the physiologically mature maintenance leaves. The average of LAI on five physiologically mature maintenance leaves and one application of folliar fertilizer treatment were 3,0087 with regression Ŷ-a1b1 = -0,1923 + 0,0237 X; R^2 = 0,8979 were effective to control Empoasca, weeds and to increase the yield.
