Substitution or Complementarity: Why do Rice Farmers Use a Mix of Biopesticides and Chemical Pesticides in China?

Abstract Recently, serious haze pollution has not only threatened the human health and food security, but also seems to have aggravated the unscientific use of pesticides by rice farmers in rural area of China. Using original data on haze pollution across China, combined with rural household survey data collected from 2014 to 2018, we conducted a detailed empirical study on the effects of haze pollution on pesticide use by rice farmers based on the theory of risk aversion. The empirical results revealed that haze pollution with higher levels of PM2.5 positively impacted the use of chemical pesticides in the rice cultivation. More precisely, with 1% increases in PM2.5 concentration, the amount of pesticide application per mu increased by 7.9%, and the average pesticide fee per mu increased by 2.3%, respectively. The results were robust to a series of tests that addressed potential endogeneity concerns, including omitted variable bias, measurement error and reverse causality. We then examined the heterogeneous effects of haze pollution increase on the use of chemical pesticides and found that the effects of haze pollution on the use of chemical pesticides to be weaker for rice farmer with more rice-planting experience, those with smaller cultivated area of rice, however, the effects on the amount of chemical pesticide application per mu to be weaker for those with rice insurance, but the effects on the average chemical pesticide fee per mu to be stronger for those with rice insurance. Our findings provide important policy implications for pesticide risk management in rural areas of developing countries.

The application of pest disesase control according to the recommendation in Balubur Limbangan has only been implemented around 47.1%, so that most of the farmers participation is still low and the conditions of farmers in the field are still using chemical pesticides. Therefore the importance of environmental friendly pest control. This research was aimed at paddy rice farmers in Balubur Limbangan, especially in the Dunguswiru Villages, Surabaya and Ciwangi. Each village is represented by one group of farmers, then selected based on certain criteria. Next determination the sample using the Slovin formula combined with Rubin's and Luck theory so that the total is 50 respondents. Then to using the Simple Random Sampling technique. The results showed the participation of rice farmers was low category. Then the factors of farmer participation in internal factors are education (implementation and evaluation), while external factors are extension activities, availability of information, support from farmer groups, and availability of infrastructure (planning and implementation aspects). Meanwhile, the lowest indicator that becomes the problem priority is the cultural pest control so it is used as counseling material.

Chemical Pesticides

Mosquitoes are vectors of many pathogens which causes serious human diseases like Malaria, Filariasis, Japanese encephalitis, Dengue fever, Chikungunya, Yellow fever and Zika virus which constitute a major public health problem globally. Mosquito borne diseases cause high level of economic impact all over the world and result in millions of death every year. They infect around 700,000,000 people annually worldwide and 40,000,000 only in India. The continuous use of synthetic pesticides to control vector mosquitoes has caused physiological resistance, toxic effect on human health, environmental pollution and addition to these, its adverse effects can be observed on non-target organisms. Synthetic chemical pesticides have been proved to be effective, but overall in last 5 decades indiscriminate use of synthetic pesticides against vector borne disease control have originated several ecological issues due to their residual accumulation and development of resistance in target vectors and their chronic effects.

The study was carried out to examine the effect of agricultural transformation on the beneficiary’s productivity and poverty of rice farmers in Kano State Nigeria. A multi-stage sampling method was employed to select 571 respondents for the study. Data were collected through structured questionnaires on respondent’s income, input and output quantities as well as their expenditures. Data were analysis using descriptive statistics, Foster-Greer-Thorbecke (FGT), Propensity score matching and LATE model. Results from the study shows that respondents productivity revealed a significant difference of about 127 kg/ha in rice productivity between participants and non-participants. Also, the LATE estimates revealed an average treatment effect ATE0 of about 222.98kg/ha. Furthermore, the project had a significant effect N11, 321.4 on the participant’s consumption expenditure than the non-participants N9980.60. Moreover, participants were, able to increase their household total expenditures by N34780 per annum. Fluctuations of input/output prices insect pests and inadequate extension visits were all the major constraints faced by the farmers. It was recommended that farmers’ information and sensitization system should be overhauled and improved. Also, attention should be given to well organize extension visits for the farmers from stake holders

The implementation of the technology performed for 2.5 months from August to October 2017. The purpose of the implementation is aimed to reduce the dependence of farmers on the use of chemical pesticides so that the farmers are aware of the negative impact of chemical pesticides. Assessing the impact of the utilization of Bintaro fruit and fruit extracts to explore ways of making Bintaro as a natural biopesticide to overcome rat attack on green bean plants in the Gluranploso village. Pest control mice can reduce the rate of loss of the crops more effectively and efficiently. Finally, with the use of those natural resources as a biopesticide material can also maintain the environmental balance

Chemical Pesticides

A basic IPM module for basmati rice as a part of integrated crop management accounting the pest prevalence and the information available from literature has been developed. As the module is location specific and dynamic, therefore needs regular updating and fine tuning depending on the location and pest prevalence. The technology has been successfully validated and implemented during 1998 to 2019 in Pusa Basmati 1, Taraori Basmati, Dehraduni Basmati, Pusa Basmati 1121 in Haryana, Uttar Pradesh and Uttarakhand with little modification and fine tuning. Implementation of the technology resulted in increase in rice grain yield i.e., 21.6% in Pusa Basmati 1 at Shikohpur, in Uttar Pradesh 21.5% in Taraori Basmati at Chhajpur in Haryana, 19.5% in Type 3 in Uttarakhand, 14.5 to 22.7% in Pusa Basmati 1121 in Haryana and 38.2% in Pusa Basmati 1121 in Uttar Pradesh over farmer's practices (FP). In all the basmati rice trials, higher yield as well as Benefit - Cost (B-C) ratio was obtained in IPM as compared to FP. Implementation of IPM led to significant reduction in uses of chemical pesticides. In case of IPM, only 1.46 application of chemical pesticides (103.2 g a.i./ha) were undertaken in Pusa Basmati 1121 against 2.8 application in FP (1214.4 g a.i./ha) at Bambawad, Uttar Pradesh. ICAR-NRRI, Cuttack developed and validated IPM module at Sigmapur (Cuttack, Odisha) non-Basmati rice variety Pooja for four kharif seasons i.e 2010-2013 using standard agronomic practices. The trial resulted in an enhancement of 47.1% yield and 26.47 % B-C ratio over FP. Additional income of Rs. 9857/- per ha was also obtained in IPM over FP. On-Farm trial on validation of IPM module in non-Basmati rice (Pooja variety) under semi deep water conditions conducted in 10 ha during rabi 2017 at Nagapur and Basudeipur villages in Khurda district of Odisha resulted in reduction in the incidence of insect pests and diseases with higher population of natural enemies as compared to FP. Rice yield was recorded 5600 kg ha-1 in IPM as against 4900 kg ha-1 in FP. Recently, ICT based e-pest monitoring and advisory has become an important component for area wise implementation of IPM at state and national level. The programme has been successfully implemented in Odisha during 2010 and 2011 under RKVY. Implementation of the programme had resulted successful management of swarming caterpillar in 13 rice growing districts of Odisha during kharif 2010 and 2011.
