Embodiment 1

[0053] Embodiment 1: 50.5% water suspension concentrate

[0054] Formula (weight ratio): metazafen 0.5%, L-lysine 50%, dispersant NNO 10%, fatty alcohol polyoxyethylene ether 4%, ethylene glycol 2%, xanthan gum 1%, water to make up 100% %.

[0055] Preparation method: first dilute L-lysine with water, then add pyraclofen to prepare a mixed solution, then add auxiliary dispersant NNO, ethylene glycol and fatty alcohol polyoxyethylene ether, grind and mix with xanthan gum, High-speed shearing and mixing to obtain a water-suspension dosage form.

Embodiment 2

[0056] Embodiment 2: 60% water dispersible granules

[0057] Formula (weight ratio): pyraclofen 20%, L-lysine 40%, sodium lauryl sulfate 8%, SP-2836 polycarboxylate dispersant 5%, sodium sulfate 2%, kaolin 10%, Diatomaceous earth makes up 100%.

[0058] Preparation method: firstly dilute L-lysine with water, then add pyraclofen to obtain a mixed solution, then add additives, pulverize through a jet mill and granulate to obtain a water-dispersible granule formulation.

Embodiment 3

[0059] Example 3: 45% dispersible oil suspension concentrate

[0060] Formula (weight ratio): pyraclofen 5%, L-lysine 40%, sodium lignosulfonate 10%, YUS-110 emulsifier 12%, ethylene glycol 3%, xanthan gum 1%, epoxy Soybean oil 2%, silicone oil 1%, vegetable oil (soybean oil) to make up to 100%.

[0061] Preparation method: Weigh pyraclofen and L-lysine into a container, add emulsifier, dispersant and soybean oil, mix and disperse at high speed, then use a sand mill to grind, and filter to obtain the Dispersed oil suspension formulation.

Abstract

The invention relates to the technical field of pesticides, in particular to a cotton defoliation ripening composition and a cotton defoliation ripening agent. The cotton defoliation ripening composition is prepared from the following components in parts by weight: 0.01 to 80 parts of pyraflufen-ethyl and 0.1 to 80 parts of L-lysine. The effective components of the cotton defoliation ripening composition comprise pyraflufen-ethyl and L-lysine, the cotton defoliation ripening composition has an obvious synergistic effect on defoliation and ripening of cotton through multiple different action modes, the effect of the cotton defoliation ripening composition is obviously superior to that of preparations such as pyraflufen-ethyl single agent, L-lysine single agent and thidiazuron*diuron, the ripening and defoliation processes can be accelerated while the dosage of different agents such as pyraflufen-ethyl is effectively reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a composition for accelerating the ripening of cotton defoliation and an agent for accelerating the ripening of cotton defoliation. 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. [0003] 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. Nowadays, mechanical harvesting of cotton is the trend of the times. In order to ensure the quality of cotton during machine harvesting, it is necessary to timely defoliate and accelerate the ripening of cotton. At present, the types of si...
