The invention relates to compositions useful in the field of agricultural chemistry and methods for making and using the compositions. The compositions include (i) a permeabilizing agent, and (ii) a active component, for example, a pesticide or plant growth regulator, and can include additional components as well, for example, flow agents. The permeabilizing agent, or a mixture of permeabilizing agents, acts as an adjuvant to the active component or chemicals to improve the degree of efficacy of the active component or speed of action of the active component. The permeabilizing agents are typically one or more chelating agents, cationic materials, anionic materials, and zwitterionic materials, and include polyphosphate salts. Examples of cationic materials include polyamines such as ethylenediamine and quaternary ammonium salts. The active components can be pesticides, herbicides, insecticides, fungicides, virucides, bacteriocides, and acaricides. Examples of suitable active components include plant growth regulators, defoliators, dessicants, transfection agents, wood treatments (CCA or other chemicals that are effective against termites), traps, disinfectants, marine paints and the like. The compositions can be prepared by mixing the components in a suitable manner, and the compositions can be used by applying the compositions to a plant in need of treatment thereof in an amount effective for the desired use, employing conventional application techniques. In one embodiment, the active components are defoliants, and the composition is used for plant defoliation, for example, with respect to cotton plants.

The invention provides a suitable machine picking group construction method of dripping irrigation cotton fields in Tarim Basin of South Xinjiang. The method comprises the steps of variety selection, plant row spacing and density configuration, irrigation and fertilizer application of cotton fields with different growing conditions, mepiquat chloride using method formulation and the like. A cotton variety constructed by a machine picking dripping irrigation cotton field group is put forward. The growth period is 131-136 days. The group has a rapid sensitivity to a defoliant; particularly, several days after spraying the defoliant, the leaf defoliation rate of the cotton field group is up to 91.2-94.5 %; the leaf inclination angle in the variety setting period is 46.5-65.1 degrees; the internode distance of fruit branches is 7-12 cm; the leaf size is medium and small; bracts are small; cotton leaves are good, and fluffs on the back of the cotton leaves are few; the ground clearance of cotton bolls at the lowermost portion of cotton plants is 18.0-22.0 cm; the covering of mulching films, and the planting mode of wide and narrow row or equal row spacing are used while planting. According to the method, not only are the leaf defoliation rate of the cotton leaves, the picking net rate of the machine picking, the fiber length of processed ginned cotton, the fiber strength of the processed ginned cotton and the picking efficiency increased, but also the loss rate of the machine picking and the impurity rate of seed cottons are reduced, and the production requirements are completely met.

The invention discloses a cotton defoliant used in the later stage of cotton, which contains 5% to 75% by weight of active ingredients buthiuron and thiadiuron, wherein the weight ratio of buthiuron and thiadiuron is 1:1 to 1:30. The dosage form of the defoliant is an environmentally friendly dosage form such as water-dispersible granules, water-suspension concentrates or dispersible oil-suspension concentrates. The water-dispersible granules and water-suspension concentrates should be added to the spray liquid in the amount of 0.3%~ 1.0% vegetable oil spray adjuvant to increase defoliation effect. The field defoliation application test of the defoliant shows that the defoliation rate investigated on the 15th day after treatment is 28.6%-37.1% higher than that of the conventional defoliating product 50% Thidiazuron WP in the market, and the boll opening rate is increased by 5.2% %~12.7%.
