Abstract/ Executive Summary:

The experiment was conducted at established rose garden of Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Jashore during 2017-18 and 2018-19 winter season (November-April). The experiment was laid out in a RCBD design with three dispersed replications. Four treatment combination were as follows: T1 =IPM package-1: Mechanical control + Sticky trap (Blue and White) + weekly spray of Azadirechtin (Bio-neem plus 1EC) @ 1.0ml/L of water, T2 = IPM package-2: Mechanical control+ Sticky trap (Blue and White)+ spray of Thiamethoxam 20% (Virtako 40SC) @ 1.5 ml/L of water, T3 = IPM package-3: Mechanical control+ Sticky trap (Blue and White)+ weekly spray Chlorphenapyr (Intrepid 10EC) @ 1 ml/L of water and T4 = Farmers practice: weekly spray Imidacloprid (Imitaf 20SL) @ 0.5ml/L of water. For mechanical control hand picking was done and harmful insect also classified as the most direct and the quickest way to remove clearly visible pests. Two color stiky trap (white and blue) were set up in each line. The lowest number of rose thrips was found in IPM package 2 (6.36 in 2017-18 and 3.03 in 2018-19) and highest in farmer’s practices (14.36 in 2017-18 and 12.40 in 2018-19). The lowest percent flower infestation of rose was recorded in IPM package 2 (9.98 to 17%) and the highest in Farmers practice (19.72 to 32.66%). The highest yield (864000 no./ha in 2017-18 and 535932 no./ha) was recorded from IPM package 2 and the lowest in farmers practice (438750 no./ha in 2017-18 and 388857 no./ha). The results revealed the highest MBCR was observed in IPM package-2 (Mechanical control+ Sticky trap (Blue and White) + spray of Thiamethoxam 20% (Virtako 40SC) @ 1.5 ml/L of water.) treated plot (17.2 to 49.7) in both the year. Finally, it may be recommended that IPM package 2 is very much effective to control thrips of rose as well as high yield and more economic return.

Program Area: Pest Management

Commodity: Rose

Objectives:

To find out the suitable eco- friendly approach to control thrips of roses

Methodology:

The experiment was conducted during winter season (November-April) in 2017-18 and 2018-19 at established rose garden of Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Jashore. The experiment was laid out in a randomized complete block design with three dispersed replications. Plant to plant distance was 1m and line to line distance was 3m. 10 plants were selected from each line. The treatments were as follows: T₁ =IPM package-1: Mechanical control + Sticky trap (Blue and White) + weekly spray of Azadirechtin (Bio-neem plus 1EC) @ 1.0ml/L of water, T₂ = IPM package-2: Mechanical control+ Sticky trap (Blue and White)+ spray of Thiamethoxam 20% (Virtako 40SC) @ 1.5 ml/L of water, T₃ = IPM package-3: Mechanical control+ Sticky trap (Blue and White)+ weekly spray Chlorphenapyr (Intrepid 10EC) @ 1 ml/L of water and T₄ = Farmers practice: weekly spray Imidacloprid (Imitaf 20SL) @ 0.5ml/L of water. The normal intercultural operations were done as and when necessary. For mechanical control hand picking was done and harmful insect also classified as the most direct and the quickest way to remove clearly visible pests. Two color sticky trap (white and blue) were set up in each line. The whole plant was thoroughly covered by spray emulsion. 5 flowers were randomly taken from 3 plants were taken for counting the number of thrips per plant and % flower infestation. Yield was taken from the selected ten plants and converted to no/ha. Data were analyzed by ANOVA (using Crop Stat 7.2) to evaluate differences between treatments, and the means were separated using least significant difference (LSD) at the 5% level of significance (p & lt;0.05).

Achievement/Findings:

From the above results it may be concluded that the IPM package 2 (Mechanical control + Sticky trap (Blue and White) + spray of Thiamethoxam 20% (Virtako 40SC) @ 0.15g/L of water.) was more effective for control thrips of rose in respect of reducing flower infestation, highest yield and economic return. Finally, the application of Thiamethoxam 20% @ 0.15g/L (Virtako 40SC) with sticky trap (blue and white) may be recommended to the thrips management in roses.
