Description

Technical Field

[0001] This invention relates to the field of crop disease control technology, specifically to the use of diphenyl sulfide compounds for the control of crop sunscald. Background Technology

[0002] Sunburn is a physiological disease that seriously affects the market quality of fruit. Prolonged intense solar radiation and high temperatures during the growing season can cause the surface temperature of the fruit to reach extremely high levels, leading to sunburn, reduced fruit quality, and increased agricultural economic losses. The peak incidence of sunburn is from June to September. The severity of the disease is directly related to factors such as weather conditions, soil conditions, orchard slope aspect, fruit orientation, management practices, and pesticide concentration. Severe drought and continuous high temperatures result in more severe symptoms; poor soil and low soil moisture content also lead to more severe symptoms.

[0003] In recent years, with the increase in global climate change and extreme weather events, the frequency and severity of sunburn have been on the rise. Furthermore, with the increasing demand for high-quality fruit, competition in the fruit industry has intensified, making the overall quality of fruit increasingly important. Fruit color and size determine fruit grade. From a physiological and biochemical perspective, the occurrence of sunburn is closely related to factors such as the accumulation of reactive oxygen species and reduced activity of antioxidant enzymes in plants. From a cultivation management perspective, reasonable irrigation, fertilization, and shading measures can effectively reduce the occurrence of sunburn. Additionally, breeding resistant varieties is also an effective way to address sunburn; however, a deep understanding of the resistance mechanisms of sunburn is currently lacking, and progress in resistance breeding is slow.

[0004] In conclusion, finding an effective technology to prevent and control crop sunburn while simultaneously improving fruit yield and quality is a key research focus and of significant importance. The applicant's research on compounds containing diphenyl sulfides has revealed that applying effective doses to crops requiring control can achieve sunburn prevention, particularly during the fruit enlargement stage. This significantly enhances crop resistance to sunburn, increases yield and improves quality, ensuring the sustainable development of agricultural production and demonstrating unexpected application value. Summary of the Invention

[0005] Based on the above, the present invention relates to the use of a diphenyl sulfide compound for the prevention and control of crop sunburn, wherein the diphenyl sulfide compound or its composition or mixture thereof is applied to the crop requiring control at an effective dose to achieve the purpose of preventing and controlling sunburn.

[0054] To make the technical solution, objectives and advantages of the present invention clearer, the present invention is described with reference to the following specific embodiments. However, the present invention can be implemented in various forms and should not be limited to the embodiments described herein.

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0056] Example 1

[0057] Trial period and location: June to October 2023

[0058] Test location: Innovation Village, Huanxi Town, Jin'an District, Fuzhou City

[0059] Test target: Satsuma mandarin

[0060] Experimental treatments: A total of 28 experimental treatments were conducted, with each tree as a plot and replicated 3 times. That is, 3 healthy and uniformly sized citrus trees were randomly selected for each treatment. An isolation row was set up between each treatment (two columns were left empty in each treatment space). All treatments used standard agronomic practices, such as pruning, girdling, pesticide spraying, and weed control.

[0061] Experimental treatment:

[0062] Table 1 Experimental Treatment

[0063]

[0064]

[0065] Application method: spraying;

[0066] Number of applications: Based on the actual field conditions and farmers' water usage habits, determine the water usage per citrus tree to be 1.8L. The amount of pesticide applied should be such that the leaves are evenly covered with the pesticide and a few drops of pesticide drip down.

[0067] Application period: Fruit enlargement period (August 5); spray once.

[0068] The experimental plots were cultivated under uniform and consistent conditions, in accordance with local Good Agricultural Practices (GAP). Citrus was fertilized twice during its entire growth period, once during the budding and flowering stage (basal fertilizer) and once during the fruit setting and stabilization stage (topdressing fertilizer). The terrain was flat, the fertility was uniform, and the irrigation conditions were good.

[0069] High temperatures caused citrus fruit to scorch, shrink, and fall off, negatively impacting fruit yield and quality. Based on meteorological data from Fuzhou, Fujian Province, this study compiled statistics on high-temperature weather conditions in Jin'an District, Fuzhou City, from June to September 2023, categorized high-temperature disasters by temperature index, and calculated the percentage of days with high-temperature disasters.

[0070] High temperature damage: 35℃<T≤38℃;

[0071] High-temperature heat damage: 38℃<T≤40℃;

[0072] Severe high-temperature heat damage: T > 40℃;

[0073] Percentage of days with high-temperature disasters (%) = (Number of days with high-temperature disasters + Number of days with high-temperature heat damage + Number of days with severe high-temperature heat damage) / Total number of days in the month × 100.

[0074] Survey: In early October (October 4), the incidence of sunburn on 100 citrus trees was randomly investigated in five directions: east, west, south, north, and center. The average value was taken and the incidence rate was recorded.

[0075] Formula for calculating sunburn injury rate:

[0076] Sunburn damage rate (%) = Number of sunburned fruits / Total number of fruits × 100

[0077] External quality indicators of the fruit: When harvesting the fruit, select 2 fruits from each of the 5 directions (east, south, west, north, and center) of the citrus tree, for a total of 10 fruits per tree.

[0078] Citrus fruits were graded according to the Chinese agricultural industry standard (NY / T1190-2006), with premium and first-class fruits defined as superior fruits, and the rate of superior citrus fruits was calculated.

[0079] Experimental Results and Analysis:

[0080] As shown in Table 2, high-temperature damage began in June 2023, with the peak period for high-temperature fruit damage occurring from June to August. In June, the high-temperature damage lasted for 11 days, accounting for 36.67% of all days. In July, high-temperature damage occurred for 13 days, high-temperature heat damage for 7 days, severe high-temperature heat damage for 2 days, and temperatures exceeding 35℃ for 22 consecutive days, accounting for 70.97% of all days. In August, high-temperature damage occurred for 8 days, high-temperature heat damage for 2 days, and temperatures exceeding 35℃ for a total of 8 days, accounting for 32.26% of all days. In September, the high-temperature damage lasted for 3 days, accounting for 10.00% of all days. The high-temperature damage to citrus fruits ended in October.

[0098] Application method: spraying; blank control: sprayed with water only.

[0099] Application time: During peak flowering period (May 20) and mid-June (June 13), spray once;

[0100] Survey period: mid-July (July 14th). For each tree, 100 fruits were randomly surveyed according to the five directions of east, west, south, north and center to investigate the occurrence of sunburn disease and record the incidence rate.

[0101] Formula for calculating sunburn injury rate:

[0102] Sunburn damage rate (%) = Number of sunburned fruits / Total number of fruits × 100

[0103] Number of applications: Based on the actual field conditions and farmers' water usage habits, determine the amount of water to be 2L per hawthorn tree. The amount of pesticide to be applied should be such that the entire tree is evenly covered with the pesticide and a few drops of pesticide run off.

[0104] According to local fertilization methods, hawthorn is fertilized twice during its entire growth period, once at the early flowering stage (basal fertilizer) and once at the fruit enlargement stage (topdressing).

[0105] Local temperatures: May has 5 days with temperatures above 30°C; June has 22 days with temperatures above 30°C, including 6 days with temperatures above 35°C; July has 26 days with temperatures above 30°C, including 3 days with temperatures above 35°C.

[0106] Experimental Results and Analysis:

[0107] As shown in Table 6, spraying with a 500-fold dilution of 10% compound V water emulsion effectively reduced the day burn rate of hawthorn to 3.73%, while the day burn rate of a 1000-fold dilution was 6.11%. The day burn rates of hawthorn treated with 500-fold and 1000-fold dilutions of 10% compound VII water emulsion were 5.79% and 6.15%, respectively.
