Problems solved by technology

[0007] 1) The above-mentioned defoliation and ripening agent is only suitable for defoliation and ripening of cotton, and the defoliation effect for other crops is poor, and the present invention finds in the research that pepper also has a higher demand for defoliation, so it needs to be developed A defoliant also suitable for peppers;
[0008] 2) The dosage of the active ingredients in the above two patent applications is ≥180 g / hectare, and the dosage of the medicine is large, so it is necessary to further reduce the dosage of the medicine
After searching, there is currently no report on the composition of cotton and pepper defoliation and ripening composed of Riguron and Thidiazuron

Embodiment 1

[0044] Embodiment 1: 60% water suspension concentrate

[0045] Formula (weight ratio): thiadiuron 20%, rituron 40%, dimethyl sulfoxide 10%, dispersant NNO 10%, fatty alcohol polyoxyethylene ether 4%, ethylene glycol 2%, xanthan gum 1%, water makes up 100%.

[0046] Preparation method: first dilute Liguron with dimethyl sulfoxide, then add thiadizuron to prepare a mixed solution, then add auxiliary dispersant NNO, ethylene glycol, water and fatty alcohol polyoxyethylene ether, after grinding Mix with xanthan gum, high-speed shearing and mixing to obtain a water-suspended dosage form.

Embodiment 2

[0047] Embodiment 2: 80% water dispersible granules

[0048] Formula (weight ratio): thiadiuron 40%, rituron 40%, sodium lauryl sulfate 2%, dimethyl sulfoxide 5%, SP-2836 polycarboxylate dispersant 5%, sodium sulfate 2 %, kaolin 5%, diatomaceous earth make up 100%.

[0049] Preparation method: first dilute Liguron with dimethyl sulfoxide, then add thiadizuron to prepare a mixed solution, then add additives such as sodium lauryl sulfate, sodium sulfate, and SP-2836 polycarboxylate dispersant , kaolin and diatomaceous earth are pulverized by a jet mill and then granulated to obtain a water-dispersible granule dosage form.

Embodiment 3

[0050] Example 3: 65% dispersible oil suspension concentrate

[0051] Formula (weight ratio): thiadiuron 15%, rituron 50%, dimethyl sulfoxide 10%, sodium lignosulfonate 5%, YUS-110 emulsifier 10%, ethylene glycol 3%, xanthan Glue 1%, epoxy soybean oil 2%, silicone oil 1%, vegetable oil (soybean oil) to make up to 100%.

[0052] Preparation method: Weigh thiadizuron and rituron into a container, add dimethyl sulfoxide, sodium lignosulfonate, YUS-110 emulsifier, ethylene glycol, xanthan gum, epoxy soybean oil, silicone oil and soybean oil, after mixing, high-speed shear dispersion, then sand milling with a sand mill, and filtration to obtain a dispersible oil suspension formulation.

Abstract

The invention discloses a defoliation and ripening composition containing thiadizuron and rituron, which includes active ingredients and auxiliary agents, and the weight ratio of the active ingredients to the defoliation and ripening composition is: thiadizuron 0.1-90% and Ligulong 0.1-90%. The composition of the present invention is formed by compounding thiadidiuron and rituron, and the combination of the two has obvious synergistic effect on the defoliation and ripening of cotton and the defoliation of pepper, which is obviously better than the single agent of thiadiuron and rituron. The effect of preparations such as long single agent, thiadizuron and diuron.

Description

technical field [0001] The invention relates to a defoliation and ripening acceleration composition, which belongs to the technical field of pesticides. Background technique [0002] Cotton is a multi-purpose important economic crop. It can be made into fabrics of various specifications and edible oil can be extracted through certain processes. Therefore, cotton plays an important role in my country's agricultural economic pattern. Cotton has an unlimited growth habit, but affected by weather conditions, when the dry frost comes every year, there are still many cotton bolls that cannot be opened in most cotton areas in my country. Cannot be guaranteed. [0003] At the same time, manual picking is a main way of harvesting peppers. This operation mode has relatively high labor intensity, relatively low efficiency and high cost. Therefore, the industrialization process of peppers is subject to certain restrictions. [0004] Therefore, mechanical harvesting of cotton and pepper...
