Effect of Cyantraniliprole against of Bemisia tabaci and Prevention of Tomato Yellow Leaf Curl Virus (TYLCV)

Abstract

To control Bemisia tabaci on tomato, we applied five different combinations of chemical treatments as below: 1) treatment of combinations of cyantraniliprole on the root area and leaf with the existing registered chemicals three times; 2) treatment of combinations of cyantraniliprole on the root area and dinotefuran + emamectin benzoate on the leaf with the existing registered chemicals three times; 3) treatment of combinations of dinotefuran on the root area and cyantraniliprole on the leaf with the existing registered chemicals three times; 4) treatment of combinations of dinotefuran on the root area and dinotefuran + emamectin benzoate on the leaf with the existing registered chemicals three times; 5) untreated control plot (Table 1). Twenty days after treatment (17 t h Aug.), the number of population of B. tabaci was zero on the 1, 2, 3, 4 treatments of combinations, and only 2 individuals were found on the 5 treatment of combination per each 20 plant. On 17 t h Sep., in the last observation, the average number of population of B. tabaci was 10.3, 10.3, 10.6 on the 1, 2, 3 treatments of combinations on the 20 plants per each combination, however, the average number of 23.3 and 37.6 were examined on the 4 and 5 treatments of combinations, respectively. TYLCV was not occurring on the 1 and 2 treatments of combinations, and presented only 3% and 17% on the 3 and 4 treatments of combinations, respectively, which indicates that the treatments (1-4) should be effective on TYLCV control as considering that 33% of TYLCV occurred on the untreated control plot. However, after the third flowering period, there is no difference among the five combinations. The amount of products was 9,148g and 9,698g on the 1 and 2 treatments of combinations, respectively, which was the most among the 5 combinations. The number of fallen fruits and the average weight of fruits showed the similar tendency.

Eco-Friendly Approaches for Controlling Sucking Pests in Chili (Capsicum Annuum L.)

“…Despite the application of pesticides for viral disease control, their use poses environmental and health threats. Yield losses due to these pests are estimated at 50% (Hosmani, 2007;Lee et al, 2018). Chilli leaf curl complex, caused by thrips and mites, leads to significant crop losses.…”

First Report of <i>Cladosporium dominicanum Zalar</i>, de Hoog & Gunde-Cim. Infecting Whitefly on Ornamental Plants in Bali, Indonesia

“…Whiteflies are significant crop pests that cause direct and indirect damage (Lee et al 2014). There are many species of whiteflies, (Hidayat et al 2018) reported a dichotomous identification key of whiteflies, completed based on morphological characteristics of 35 collected species in Bogor, Indonesia.…”

Whitefly (Bemisia tabaci) Management (WFM) Strategies for Sustainable Agriculture: A Review

“…Whiteflies are tiny sugar-robbers that originated from southern Asia but are now found across all regions of the globe, most notably in tropical regions [3,4], except Antarctica [5]. Their aggressive feeding on plant sap from leaf tissue causes substantial losses to agricultural crops [6]. Each female is capable of producing about 320 eggs within a single life cycle [7,8].…”

“…Thus, B. tabaci is ranked as a highly disastrous insect pest worldwide [11,23]. Due to accumulated impact of direct damage and secondary damages through transmission of viruses, whiteflies pose socioeconomic challenge [6,10]. Many studies across the globe have attempted to reduce its impact on sustainable agricultural productivity [24][25][26].…”
