Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 11
Abstract
To understand the incidence of citrus pests and pesticide use in 27 townships of Huizhou, Shaoguan and Meizhou in the northeastern region of Guangdong Province, and to lay a foundation for the rational development of citrus pesticide reduction and efficiency in Guangdong Province. This study used a fixed-point survey to determine the type and distribution of citrus diseases in Guangdong Province. A comprehensive census method was used to clarify the types of pesticides used, the amount of pesticides used in each region, and their input. Survey results showed that the main diseases in Huizhou, Shaoguan, and Meizhou were citrus anthracnose and citrus canker. The main pests were: citrus hibiscus, red spider, and citrus leaf miner; The main weeds are Cowgrass, Solanum nigrum and Setaria; all investigated. There are 50 kinds of pesticide products used by farmers in the region, and the ratio of each type of pesticide is 25 (pesticides): 22 (bactericides): 4 (herbicides), pesticides are currently Farmers used the largest category and number of pesticides. In terms of pesticides, the proportion of various species in all surveyed regions was: Organophosphates＞Acaricides＞ Nicotine Category = Pyrethroids＞ Macrolides＞ Tertiary ketones = carbamates,accounting for 28.0%, 24.0%, 14.2%, 14.2%, 8.0%, 4.0%, 4.0%; Bactericide used was: agent bactericide＞ copper bactericide＞ organic sulfur bactericide＞ substituted benzene bactericide = compound bactericide＞ antibacterial bactericide = other bactericide, accounting for: 45.5%, 22.7 %, 13.6%, 9.1%, 9.1%, 4.5%, 4.5%; Herbicides mainly use glyphosate and glufosinate. No new diseases pests and weeds were found in citrus in the surveyed areas. In terms of drug dosage, The use of chemical pesticides in various regions is generally unreasonable.
