Description

Technical Field

[0001] The present invention belongs to the technical field of medicine fertilizers, and particularly relates to a medicine fertilizer granule containing chlorantraniliprole and clothianidin and its uses. Background Art

[0002] Guangxi Zhuang Autonomous Region is a key area for the development of the sugar industry in China. The planting area of sugarcane has always ranked first in the country, making great contributions to the development of sugar materials. In recent years, pests such as sugarcane borers and sugarcane thrips have become increasingly serious. Without good control measures or timely control, it will affect the yield of sugarcane and lead to a serious reduction in sugarcane production. Especially in sugarcane pests, the damage caused by sugarcane borers is the most serious. Sugarcane borers, commonly known as borer worms, are mainly distributed in sugarcane-growing areas such as Guangdong, Guangxi Zhuang Autonomous Region, Yunnan, Guizhou, and Hainan. The species include strip borer, yellow borer, white borer, large borer, and Taiwan rice borer. Sugarcane borers occur in multiple generations annually. Often, several borers occur simultaneously, with strong reproductive ability, strong concealment, overlapping generations, and significant differences in occurrence in different regions. It is difficult to control in production. They damage throughout the growth period of sugarcane. At the seedling stage, they damage the growth point and cause dead heart seedlings; in the middle and late growth stages, they bore into and damage the sugarcane stem, destroying the stem tissue, hindering the growth of sugarcane, reducing the yield and sugar content, and causing wind breakage.

[0003] For many years, the pesticides used to control sugarcane borers have mostly been highly toxic and highly residual pesticides, causing serious pollution to the environmental water and soil and harming humans, livestock, and natural enemies. The unreasonable use of these chemical pesticides has made the 3R problem more and more prominent, which is very unfavorable for the safe production of sugarcane. The insecticidal pesticides for sugarcane on the market still have problems such as "high toxicity, serious residue, unstable efficacy, harm to biological natural enemies, and the registered crops are not sugarcane". Therefore, carrying out research on related problems, developing, producing, and promoting more advanced and stable related products is of great significance for the safe, efficient, and stable production of sugarcane.

[0020] According to the following embodiments, the present invention can be better understood. However, those skilled in the art can easily understand that the content described in the embodiments is only used to illustrate the present invention, and should not and will not limit the present invention detailed in the claims.

[0021] Example 1 : Influence of Different Carriers on the Stability of Pesticide-Fertilizer Granules

[0022] Preparation Process: After weighing the technical material, carrier, fertilizer (N, P, K mixed in a certain proportion), and additives in certain proportions, mix them evenly, knead with a binder, granulate, dry at 60 °C for 8 min, and obtain the finished product through screening.

[0023] Specific Formulation is as Follows: Technical Material: Chlorantraniliprole 0.04%, Clothianidin 0.12%; Dispersant Nekal BX (Shanghai Puzhen Biotechnology Co., Ltd.) 6%; Binder Polyvinyl Alcohol (Shanghai Aladdin Biochemical Technology Co., Ltd.) 5%; Fertilizer: Urea 15%, Monoammonium Phosphate 15%, Potassium Chloride 10%; Carrier: Make up to 100%.

[0024] Testing Method: Determine according to "2.3 Other Preparations" in GB / T19136 - 2003. After the test sample is cooled to room temperature, determine the mass fraction of the active ingredient in the test sample within 24 h, and use high performance liquid chromatography for separation and determination.

[0025] Table 1 Influence of Different Carriers on the Stability of Pesticide-Fertilizer Granules

[0026]

[0027] It can be seen from Table 1 that different carriers have a certain influence on the active ingredients chlorantraniliprole and clothianidin. Among them, bentonite and diatomite have a greater influence on the stability of chlorantraniliprole and are not suitable for preparing pesticide-fertilizer granules. Kaolin, silica, diatomite, attapulgite, and bentonite have a smaller influence on the stability of clothianidin; especially in the attapulgite system, the decomposition rate of clothianidin is only 4.10%.

[0028] Table 2 Influence of Different Carrier Combinations on the Stability of Pesticide-Fertilizer Granules

[0029]

[0030] It can be seen from Table 2 that compared with the single use of carriers, after combining the carriers silica and attapulgite, the stability of the active ingredients can be complemented to a certain extent; and when the ratio of silica to attapulgite is 10:1 - 1:10, the decomposition rate of chlorantraniliprole is between 5.22 - 5.74%, and the decomposition rate of clothianidin is between 4.35 - 4.72%. There is no antagonistic effect between the carrier blends, and there is no significant increase in the active decomposition rate.

[0031] Example 2 : Influence of Different Fertilizer and Carrier Combinations on the Stability of Active Ingredients

[0032] Preparation process: After weighing the technical material, binder, carrier, fertilizer and additives in certain proportions, mix them evenly, knead with the binder, granulate, dry at 60 °C for 8 min, and obtain the finished product through screening.

[0033] The specific formula is as follows:

[0034] Technical material: Chlorantraniliprole 0.04%, Clothianidin 0.12%; Dispersant Nekal BX (Shanghai Spectrum Vibration Biotechnology Co., Ltd.) 6%; Binder Polyvinyl Alcohol (Shanghai Aladdin Biochemical Technology Co., Ltd.) 5%; Fertilizer: 15%; Carrier (Silica white + Attapulgite = 1:1) to make up 100%.

[0035] Testing method: Determine according to "2.3 Other preparations" in GB / T19136-2003. After the test sample is cooled to room temperature, determine the mass fraction of the active ingredient in the test sample within 24 h, and use high performance liquid chromatography for separation and determination.

[0036] Table 3 Influence of several common fertilizers on the stability of active ingredients

[0037]

[0038] As can be seen from Table 3, calcium magnesium phosphate fertilizer has a greater influence on the stability of the active ingredient Chlorantraniliprole; ammonium sulfate has a greater influence on the stability of the active ingredient Clothianidin; the remaining urea, ammonium chloride, ammonium sulfate, monoammonium phosphate, diammonium phosphate and potassium chloride have a smaller influence on the stability of the active ingredient.

[0039] Example 3: Influence of different dispersants on the stability of the pesticide-fertilizer granule

[0040] The preparation process is as follows: After weighing the technical material, binder, carrier, fertilizer (N, P, K are mixed in certain proportions) and additives in certain proportions, mix them evenly, knead with the binder, granulate, dry at 60 °C for 8 min, and obtain the finished product through screening.

[0041] Testing method: Determine according to "2.3 Other preparations" in GB / T19136-2003. After the test sample is cooled to room temperature, determine the mass fraction of the active ingredient in the test sample within 24 h, and use high performance liquid chromatography for separation and determination.

[0042] Table 4 Formulation of 0.16% Chlorantraniliprole·Clothianidin pesticide-fertilizer granule

[0043]

[0044]

[0045] As can be seen from Table 4, the choice of dispersing aids has a certain impact on the stability of the active ingredient; when the dispersants are Tersperse 2700 and Morwet D-425, the decomposition of the active ingredient can be reduced. Especially when Tersperse 2700 and Morwet D-425 are combined, the decomposition of the active ingredient can be significantly reduced.

[0046] Example 4 : Control effect of the medicine-fertilizer granule on sugarcane borers

[0047] Experimental design: The test plot is located in a sugarcane plantation in Yongning District, Nanning City, Guangxi Zhuang Autonomous Region. The sugarcane field is a hillside terrace with medium fertility. The soil type is purple sandy loam weathered from sandstone, and the soil layer is loose. 3 treatments are set up in the experiment, and each treatment is repeated 3 times. The area of each plot is 45m 2 , and a randomized block arrangement is adopted. Isolation rows are set between blocks and between plots, and protective rows are set around. The medicine is applied during the weeding and soil hilling of the sugarcane seedling stage. Small ditches are dug around the sugarcane planting holes, and the medicine is scattered into the ditches according to the set treatment dose of the medicine, and the medicine is completely covered with soil layer. Only soil hilling treatment is done in the blank area, and no medicine and fertilizer are applied. 45 days after the medicine application, the total number of sugarcane seedlings, the number of dead heart seedlings and other data in each plot are investigated.

[0048] The calculation formula is as follows:

[0049] Dead heart rate (%) = number of dead heart seedlings / total number of seedlings × 100%;

[0050] Relative control effect (%) = (control dead heart rate - treatment dead heart rate) / control dead heart rate × 100%.

[0051] Table 5 Control effect of the medicine-fertilizer granule on sugarcane borers

[0052]

[0053] As can be seen from Table 5, the medicine-fertilizer granule prepared by the present invention has excellent control effect on sugarcane borers, and the control effect is greater than 88%.

[0054] The above is only the preferred implementation mode of the present invention. For those skilled in the art, without departing from the raw materials of the present invention, appropriate improvements can be made, and these improvements are also within the protection scope of the present invention.
