Description

Technical Field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a medicated fertilizer granule containing chlorantraniliprole and clothianidin and a use thereof. Background Art

[0002] Sugarcane is an important sugar and energy crop in my country. The sugarcane industry is an important pillar of economic development in the main producing areas in southern my country and the main source of farmers' income. Its development is of great significance for optimizing industrial structure, increasing agricultural income, improving people's lives, and strengthening the basic position of agriculture. Pests are one of the main factors affecting sugarcane yield, sugar content and quality, especially borers, which have become an important factor restricting sugarcane production and income. For a long time, the use of single chemical agents has caused sugarcane pests in some areas to develop varying degrees of resistance, and the prevention and control effect has been significantly reduced. In addition, the residues and accumulation of active ingredients and metabolites of pesticides cause pollution to agricultural products, resulting in a decrease in food quality and safety. Therefore, it is necessary to develop efficient, low-risk, low-residue, and long-lasting pesticides for use in sugarcane fields.

[0003] Guangxi Shoukong Biotechnology Co., Ltd.'s patent application patent document CN202011466888.X discloses a kind of medicated fertilizer granule containing chlorantraniliprole and dimethomorph, which has a good control effect on sugarcane borers, and can also prevent other sugarcane pests such as aphids and thrips. The company's patent document CN202310434318.X discloses a kind of medicated fertilizer granule containing chlorantraniliprole and clothianidin and its use. A medicated fertilizer granule containing chlorantraniliprole and clothianidin contains the following weight percentage components: chlorantraniliprole 0.01-0.5%, clothianidin 0.01-0.5%, fertilizer 20-60%, dispersing aid 1-10%, binder 2-5%, and filler supplement 100%. The medicated fertilizer granule of the present invention has a good control effect on sugarcane borers, and can also prevent other sugarcane pests such as aphids and thrips. However, in practical application, its control effect on stem borers and improvement of agronomic traits of sugarcane need to be further improved. Summary of the invention

DETAILED DESCRIPTION

[0017] The present invention can be better understood according to the following examples. However, it is easy for those skilled in the art to understand that the contents described in the examples are only used to illustrate the present invention, and should not and will not limit the present invention described in detail in the claims.

[0018] Example 1: 0.16% chlorantraniliprole and clothianidin fertilizer granule formula

[0019] Test materials: Test materials were purchased from the market, and the specific formula is shown in Table 1

[0020] Table 10. Formula of 16% chlorantraniliprole and clothianidin fertilizer granules

[0021]

[0022] Preparation method: After weighing the original drug, synergist, fertilizer, wetting dispersant, filler, etc. in a certain proportion, mix them evenly with a 0.16% chlorfenapyr·thiamethoxam fertilizer granule formula, add a binder and knead them, granulate them, dry them at 50°C for 15 minutes, and obtain the finished product by screening. The fertilizer granules are qualified after testing.

[0023] Example 2 :Effect of 0.16% chlorantraniliprole·clothianidin fertilizer granules on the control of sugarcane borer and its influence on agronomic traits

[0024] Test agent: Example granule formulations 1-7; positive control agent (formulation 4 in CN202310434318.X).

[0025] Test method: The test adopts random block-level arrangement method, with isolation rows set between blocks and plots, and protection rows set around. Each treatment is repeated 3 times, and the plot area is 60m2. During the seeding period, the Chinese medicinal fertilizer granules of Example 1 + 20kg of compound fertilizer were applied in the furrows, and 30kg of compound fertilizer + 5kg of urea were applied during the large soil-raising period;

[0026] Methodology:

[0027] Investigation on the control effect of sugarcane borer: The dry heart rate of sugarcane in each treatment group was investigated 60 days after the application of the drug to evaluate the field control effect of each treatment on sugarcane borer. The control effect calculation formula is as follows:

[0028] Dead core rate (%) = number of dead core seedlings / total number of seedlings × 100%;

[0029] Preventive effect (%) = (control withered heart rate - treatment withered heart rate) / control withered heart rate × 100%.

[0030] Investigation on agronomic traits of sugarcane: The plant height of sugarcane in each treatment group was investigated 120 days after application of the drug.

[0031] The test results are shown in Table 2.

[0032] Table 2 Control effect of fertilizer granules on sugarcane borer

[0033]

[0034]

[0035] As shown in Table 2, compared with the positive control, the medicated fertilizer granule formulations 1-7 of the present invention can significantly improve the control effect of the agent on sugarcane borers, especially the control effect of formulation 1 on sugarcane borers is the highest at 93.4%, which is significantly different from other treatments.

[0036] Table 3 Effect of fertilizer granules on sugarcane plant height

[0037]

[0038] As shown in Table 3, 120 days after application, the synergist component in the formulas 1-7 of the fertilizer granules of the present invention has a growth-promoting effect on sugarcane. The plant height 120 days after application is significantly higher than that of the positive control, especially the sugarcane plant height of formula 1 is 148.3 cm, which is significantly different from other treatments.

[0039] The above is only a preferred embodiment of the present invention. For those skilled in the art, appropriate improvements can be made without departing from the raw materials of the present invention, and these improvements are also within the scope of protection of the present invention.
