Disease and Type of Prevention Method
The disease that is being studied is the Rice Blast disease. It is one of the most serious diseases related to rice which is caused by the bacteria Magnaporthe grisea. It could result to a loss of about 10 to 20 % of rice production. It is a common agricultural problem around the world and it could reduce the global rice production of up to 40 to 50%. The rice blast disease also attacks large amounts of rice fields in China during the 1990s (Peng et al., 2016). In the study, the rice blast in Nanchong City was studied and a primary type of prevention method was used. They used comprehensive prevention and control technologies in order to reduce the prevalence or onset of the disease.
The Prevention Method
The prevention method used in the study is the comprehensive prevention and control technologies. The researchers analyzed the blast control efficiency of the applied pesticides at different growth stages. The prevention method was aimed to reduce the occurrence or the blast damage of the disease as well as to reduce the use of pesticides, control costs and the environmental pollution. The researchers used the data from the systematical monitoring, regular surveys, rice blast incidence, rice blast resistance identification, meteorological data analysis and experiments. According to their study, the prevention method is based on the idea that appropriate treatment method is necessary to reduce the blast damage.
Study Population/Samples
The population or the sample in the study is the whole rice fields which are available and operating in Nanchong City in China. The data from various experiments, data file and studies have been used in order to formulate a comprehensive prevention and control technology in order to reduce the prevalence or onset of the disease. Some of the information used in the study includes the occurrence of rice blast in Nanchong City, the rice blast incidence among hybrid crops, and the use of pesticides in the rice fields at Nanchong City and effects of the pesticides on the prevalence of rice blast in the Nanchong City during the periods of 1990 to 2014.
Conclusion of the Study
The study concluded that the rice blast in Nanchong City was effectively controlled by the comprehensive prevention and control technology. The frequency of the severe rice blast incidence in Nanchong City has reached up to 50 % since 1997. However, it reduce up to 2 % in 2014 due to the comprehensive prevention and control technology. In addition, the pesticide use was also reduced by 4,523 tons. According to the study, almost 327,00 tons of rice grains are considered pollution-free which indicates that the comprehensive prevention and control technology has improved the rice production in the city.
Is it Reliable?
The study is considered reliable since it used government-based surveys and statistics. The study is also considered reliable since it used data and information from reliable sources, experiments or studies. Lastly, the study also used primary sources which are the main factors for its reliability.
Recommendations for Future Study
Future studies could use other types of agricultural disease or other types of crops to focus on. The study is based only on surveys and data from other studies. It does not require large amounts of resources. This could be advantageous if other researchers could use other types of disease or other crops.
