Pesticide use in vegetable production: A survey of Vietnamese farmers' knowledge

Abstract

Akköprü A., Özaktan H. (2018): Identification of rhizobacteria that increase yield and plant tolerance to angular leaf spot disease in cucumber. Plant Protect. Sci., 54: 67-73.The biological control of angular leaf spot disease (ALS) of cucumbers (Cucumis sativus), caused by pseudomonas syringae pv. lachrymans (psl), using promising rhizobacteria (RB) and to compare RB efficacy to that of acibenzolar-S-methyl (ASM) was investigated. Effects of ASM and RB isolate pseudomonas putida AA11/1 that was isolated from the healthy cucumber root surface on disease severity and plant growth were evaluated using ALS-susceptible and tolerant cucumber cultivars in a growth chamber and a soilless growing system. ASM and AA11/1 significantly reduced average disease severity of ALS by 69 and 34% in the susceptible cultivar and 92 and 21% in the tolerant cultivar, respectively. ASM treatment significantly reduced psl populations, but AA11/1 did not inhibit psl growth in either cultivar. In the soilless system, disease severity was limited by either ASM or AA11/1, whereas only AA11/1 treatments significantly increased cucumber yield by 68 and 33% in the susceptible and tolerant cultivar, respectively.

Examining Factors that Influence Harumanis Farmers’ Intention to Use Safe Pesticides

“…For PBC, this study found a contradictory result as compared to previous studies in various contexts. PBC consistently has a significant positive relationship with behavior in the study about food consumption (Ekasari & Zaini, 2020), environment such as waste separation behaviour (Razali et al, 2020), the use of eco-friendly reusable bag (Ekasari & Zaini, 2020), and agriculture sector such as the use of pesticide among farmers such as cereal (Bagheri, Emami, et al, 2019), cucumber (Abadi, 2018), and vegetables (Nguyn et al, 2018).…”

“…Moreover, they understand the importance of using safe pesticide for export products. The study about knowledge in various research contexts exhibit that knowledge has a huge impact on the behavior to use pesticides among farmers (Abadi, 2018;Khalid et al, 2020;Maddah et al, 2020;Masruri et al, 2021;Nguyn et al, 2018). However, when tested as the extension of TPB, knowledge has been found to lead to a mixed result.…”

“…Besides moral norm, knowledge is another variable used by scholars as the extension of TPB. The research about knowledge in the use of pesticides was conducted using various design and data analysis methods; as examples, knowledge as the intervention in quasi-experimental (Maddah et al, 2020), comparative analysis (Khalid et al, 2020;Masruri et al, 2021) and modelling using hypothesis testing (Abadi, 2018;Nguyn et al, 2018). The results of these studies reveal that, knowledge has a huge impact on the behavior to use pesticides among farmers.…”

Factors affecting the management of pesticide business: the case Vietnam

“…The study shows that farmers knowing pesticide by training normally taking care of the brand name of the pesticide; Van et al (2013) indicate that, an overall improvement of pesticide business management only relies on better government intervention, focusing on more stringent implementation and enforcement of regulation. Several other studies, for instance, Mengistie et al (2015); Hoi et al (2016); Nguyen et al (2013); Nguyen et al (2018) also emphasize to five main factors affecting the implementation of regulations on the management of pesticide business, including state policies, management apparatus, awareness of pesticide traders, dissemination activities and inspection activities of pesticide business.…”

Vegetable Farmers Knowledge and Safety Practices towards Pesticides: Results from Field Observation in Southeastern DR Congo

“…A recent survey conducted in Lubumbashi reported that 97.6% of vegetable famers spray pyrethroid and organophosphate insecticides because of their effectiveness and immediate action on pests [4]. Despite their perceived benefits, misuse and poor handling practices of pesticides can lead to inappropriate spraying equipment, pesticide application during bad weather conditions ( strong winds or high temperature, low humidity) [9,10] and the improper combination of several chemicals [11][12][13]. In many countries like DR Congo, sale agents who are the main source of information for farmers on pesticide choice and use [5,14] have also limited knowledge of plant protection products and are not trained to handle safely chemicals [15].…”
