“…It can be seen that position D3 in a pomelo growing area produces the highest Cu content. The use of large amounts of fertilizers, pesticides, fungicides over a long period of time, the frequency of spraying per crop can be 24 times or more for citrus crops, contributing to an increase in the concentrations of heavy metals in soil (Kelepertzis, 2014;Adami et al, 2019). However, the Cu content in the soil of the study area is still within the allowable limit QCVN 03-MT:2015/BTNMT -Agricultural soil (Cu=100 mg/kg).…”

The study aimed to evaluate the occurrence of some heavy metals in agricultural soil in the Hau Giang province, Vietnam. The geographical accumulation index (Igeo), pollutant load index (PLI) and ecological risk index (RI) are used to assess the pollution levels and potential ecological risks due to the presence of heavy metals in agricultural soil. The results showed that the mean concentrations of Cu, Pb and Zn in the soil ranged from 16. 25-40.32, 18.05-29.92 and 52.78-147.22 mg/kg, respectively, within the limits of QCVN 03-MT:2015/BTNMT. Cluster analysis showed that Pb originated from the process of using fertilizers, especially phosphate fertilizers in farming. Cu and Zn possibly share a common origin from the use of pesticides and fungicides in agricultural production. The Igeo value of Cu, Pb and Zn gradually increases in the order of Cu < Zn < Pb. The PLI (1.03-1.97) reflected that the soil in the study area is moderately polluted. The RI (14.80-25.33) represented a low potential ecological risk. In particular, position D3 had the highest level of pollution and risk among the study sites. Pb had the highest level of accumulation in soil with the highest single ecological risk factor; thus, measures should be taken to limit the source of Pb generation. The results of the study also indicated that ingestion route is the main exposure pathway by which heavy metals can be harmful to humans.

“…However, smallholder farmers have a low knowledge level of field pests and lack a certain level of technical skills and experience to operate. Thus, they are more likely to use low-toxicity and high-efficiency biological pesticides for pest control [48].…”

Agricultural extension services play an important role in promoting pesticide reduction and green production, although the mismatch between farmers’ needs and service supply in rural China seriously affects the application and promotion of biological pesticides, which has been generally ignored by existing studies. Taking 1160 rice farmers in Hubei Province, China, as an example, this study constructs a need-supply fit model of agricultural extension services from the perspectives of need and supply. We further use the logit model and propensity score matching method (PSM) to estimate the effect of service need-supply fit on farmers’ biological pesticide adoption behavior. The specific results are as follows: First, the level of need-supply fit for agricultural extension services was low for the overall sample. This indicates that the agricultural extension service supply is not consistent with the actual needs of farmers. Second, the agricultural extension service need-supply fit significantly and positively affects farmers’ biological pesticide adoption behavior. Third, there are significant differences in farmers’ biological pesticide adoption behaviors under different need-supply fit. When the level of service need-supply fit exceeds the 0.2 threshold, the positive effect of service need-supply fit on farmers’ biological pesticide adoption behavior gradually increases. Fourth, the agricultural extension service need-supply fit indirectly increases farmers’ motivation to adopt biological pesticides by regularizing biological pesticide use behavior and alleviating path dependency. Therefore, the main body of agricultural extension services should optimize the adjustment of the supply mode of agricultural extension services to fully grasp the reality of farmers’ need for biological pesticides in order to promote the application of biological pesticides.

“…Therefore, effective, environment‐friendly control strategies are urgently required (Blaustein et al, 2018). Biological control of the vector could be a good method to limit the spread of HLB without causing the environmental problems associated with excessive pesticide use (Adami et al, 2019).…”
