Toxicity parameters of a new cotton defoliant «UzDEF-K» were studied in various ways of exposure. The preparation is established to be referred to the IV hazard class. Hygienic standards of a defoliant in environment objects andfoodstuffs (maximum concentration limit in reservoir’s water - 2,0 mg/l, in working zone air - 2,5 mg/m and atmospheric ambient air - 0,2 mg/m were set). Maximum allowable limit in foodstuffs - cotton oil: “it isn’t allowed”, APC in the soil - 1,15 mg/kg), were scientifically based regulations of safe using of a preparation in agriculture are: a sanitary protection zone-100 m, in terms of attendance at work - 5 days.

Verticillium wilt, caused by the pathogenic fungus , has emerged as a severe threat to cotton globally. However, little is known about the genetic diversity of this pathogen in an infected single cotton plant. In this study, we isolated three new strains from the disease stems of from the cotton field in Western China and assessed their pathogenicity to the cotton cultivar Xinnongmian-1 and its two transgenic lines, as well as two laboratory strains, VD592 and VD991.

Verticillium wilt is a soil-borne disease caused by distinct vegetative compatibility groups (VCG) of the fungus . Defoliating (VCG 1A) and non-defoliating (VCG 2A) pathotypes of have contributed to yield losses of cotton production in Australia. To study the virulence and the infection process of on cotton, two isolates, one representing each VCG, have been transformed with fluorescent protein genes.

Low temperatures decrease the thidiazuron (TDZ) defoliation efficiency in cotton, while cyclanilide (CYC) combined with TDZ can improve the defoliation efficiency at low temperatures, but the mechanism is unknown. This study analyzed the effect of exogenous TDZ and CYC application on cotton leaf abscissions at low temperatures (daily mean temperature: 15°C) using physiology and transcriptomic analysis. The results showed that compared with the TDZ treatment, TDZ combined with CYC accelerated cotton leaf abscission and increased the defoliation rate at low temperatures.

Spraying harvesting aids is an important step before the mechanical harvesting of cotton. To clarify the direct relationship between the droplet density and the defoliation effect of cotton harvest aid solutions, we evaluated the relationship between the droplet density and the defoliation effect. The determination method and evaluation standard of the number of droplets required per square centimeter to achieve 50% leaves defoliation (DN) of the harvest aid solution were further explored.

Verticillium wilt (VW) is an important and widespread disease of cotton and once established is long-lived and difficult to manage. In Australia, the non-defoliating pathotype of is the most common, and extremely virulent. Breeding cotton varieties with increased VW resistance is the most economical and effective method of controlling this disease and is greatly aided by understanding the genetics of resistance.
