The comprehensive prevention and control measures in January are as follows: if fruit preservation and frost prevention are needed in winter, they can be implemented in the current conventional way, and gradually transition to organic cultivation according to the conditions of different parks; Timely clean up the fallen leaves, dead fruit, fruit bags, weeds and other accumulated materials in the orchard and take them away from the orchard and burn them or bury them deeply to eliminate the overwintering pests and pathogens in the orchard.
| Month | Occurrence of diseases and pests | Comprehensive prevention and control measures |
| January | Disease and insect pests are dormant and overwintering in this month | 1. If it is necessary to protect fruit and prevent frost in winter, it can be implemented in the current conventional way, and gradually transition to organic cultivation according to the conditions of different parks; 2. Timely clean the fallen leaves, dead fruits, fruit bags, weeds and other accumulations in the orchard, and take them away from the orchard and burn them or bury them deeply to eliminate the overwintering pests and pathogens in the orchard; |
| February | Some diseases and insect pests are dormant, and a few overwintering red spiders begin to lay eggs; Scab disease and anthrax began to infect. | 1. Fertilization of soil: apply bio-organic fertilizer in open loop ditch or strip ditch, 500kg per mu; 2. Spring garden cleaning: 200 times of Mancuiyuan (mineral oil)+400 times of Youmancui (matrine); 3. At the early stage of fruit ripening, spray Weicui (amino acid) 400 times solution once to improve the quality and increase the sugar content of fruit. |
| March | The first generation of red spider spawning peak; The infection period of scab, ulcer and acute anthrax. | 1. In the bud stage, spray the solution diluted by 1000 times (15g mixed with 15kg water) with Dokot (plant immune protein) once every 15-20 days to improve the immunity of citrus and cooperate with disease and pest control; 2. Before flowering, the first generation of red spider eggs and young mites can be controlled by using 500 times of veratrine solution, which can release predatory mites after treatment; 3. Before flowering, use the 400 times solution of Candi (berberine) to control scab and anthrax, and control the disease at the initial infection stage; 4. Topdressing outside the root: Qijia (humic acid) 5-10kg/mu. |
| April | If the first generation of red spider missed the best control period, the occurrence of red spider would be serious; Acute deciduous anthrax begins to occur, and scab infection is the best time. | |
| May | In this month, crustacean, leafminer and resinosis (sand skin disease) started. | 1. Spray 1000 times diluted plant immune protein once during the development of young fruit, improve the immunity of citrus, promote the growth and development of young fruit, and cooperate with disease and pest control; 2. The effective control of scale insects from the full hatching period to the second instar of the young scale insects was carried out by using the 400 times solution of Nongwei (veratrine)+300 times solution of Mancuiyuan (mineral oil) (according to the actual situation, the occurrence of red scale insects was controlled by continuous application of 2-3 times); 3. Use the 500-fold solution of Metarhizium anisopliae CQMa421 (produced by Julixin Company)+the 400-fold solution of Bacillus subtilis Puze to control leaf miner and sand skin disease. |
| June | This month is the peak period of resin disease (sand skin disease) infection, and other diseases and insect pests are similar to May. | 1. Foliar topdressing: spray green crops (humic acid) 300 times; Selective root irrigation and application of Qijia (humic acid) 2-5kg 2. Before the onset of sand skin disease, use the 400 times solution of Candi (berberine)+400 times solution of Bacillus subtilis Puze to control the disease during the infection period; 3. Use Metarhizium anisopliae CQMa421 (produced by Julixin Company) 500-fold solution+Nonfovir (veratrine) 400-fold to control leaf miner. |
| July | Chronic anthrax begins to occur, and rust tick, red spider, aphid, whitefly and leafminer may occur. | 1. Use 500 times of Wanruochui (veratrine)+500 times of Baojiakang (matrine) to control rust tick, red spider, aphid and whitefly; 2. Use 400 times of Xiangmingrui (osthol) solution to control anthrax; 3. When the shoots sprout in summer and autumn and the new branches sprout no more than 3 mm, or when the rate of damage to the new leaves reaches about 5%, use the 500-fold solution of Metarhizium anisopliae CQMa421 (produced by Julixin Company) to control the leaf miner (used for three consecutive times, with an interval of 7-10 days). |
| August | In this month, we should do a good job in farming operations, and at the same time, we should timely apply drugs according to the occurrence of diseases and insect pests. | |
| September | Red spider, rust tick and leafminer may occur, and anthrax and canker are repeatedly infected | 1. Use 500 times of Wanruochui (veratrine)+500 times of Baojiakang (matrine) to control rust tick and red spider; It can be combined with predacious mite control after treatment; 2. Use 500 times solution of Metarhizium anisopliae CQMa421 (produced by Julixin Company) to control leaf miner 3. The 400 times solution of Xiangmingrui (osthol) was used to control anthrax and control the disease in the period of repeated infection. |
| October | Anthrax, red spider and yellow spider may occur | 1. Fertilization of soil: apply bio-organic fertilizer in open loop ditch or strip ditch, 300 kg per mu; 2. Use 400 times of Xiangmingrui (osthol) solution to control anthrax; 3. Use 500 times of veratrine to control red spider and yellow spider; 4. During fruit expansion, plant immune protein diluted by 1000 times was sprayed once to prolong the picking period and promote growth and yield. |
| November | Some diseases and insect pests are dormant, and a few overwintering red spiders begin to lay eggs | 1. Fruit preservation and frost prevention in winter can be implemented in the current conventional way, and organic cultivation can be gradually transferred according to the conditions of different parks; 2. Qingyuan: 150 times of Mancuiyuan (mineral oil)+400 times of Youmancui (matrine); |
| December | 1. Fruit preservation and frost prevention in winter can be implemented in the current conventional way, and organic cultivation can be gradually transferred according to the conditions of different parks; |
