Protein extracted from boll weevil larvae causes abscission of cotton flower buds and debladed petioles. Abscission of buds is preceded by a rapid and persistent flaring of bracts; cell proliferation is induced in the abscission zone of debladed petioles. A possible mode of transmission of the agent from larva to bud tissue is discussed.

In this paper we give examples which show that the convolution theorem (Boll, [1], Hajek, [2]) cannot be extended to infinite-dimensional shift experiments. This answers a question posed by van der Vaart, [9], and which has been considered also by LeCam, [5].

Pantoea ananatis is a bacterium with versatile niches that vary from pathogenic to beneficial. We present the genome of strain CFH 7-1, which was recovered from a diseased greenhouse cotton boll previously caged with a field-collected cotton fleahopper (Pseudatomoscelis seriatus). These data will assist in deciphering the infection process.

Peak bloom is one of the most recognizable periods in cotton development Fields may become blanketed with white blooms as boll loading accelerates to a maximum. This landmark developmental stage signals that a shift is occurring in the crop's biology and your management priorities. This newsletter will profile the crop at peak bloom and outline some management considerations that can affect per...

Two field experiments were carried out in Agricultural Research and Experimental Station, Faculty of Agriculture, Cairo University, Giza, Egypt (2019 2020) to study the response Egyptian cotton cultivars (Giza 92, Giza 94 95) growth, yield fiber properties foliar zinc (Zn) rates (0, 100 200 ppm) nitrogen (N) fertilizers sources; urea (U), ammonium nitrate (AN) sulfate (AS).  Cultivars, N source...

We characterized the level of risk of boll weevil, Anthonomus grandis grandis Boheman, reintroduction to an eradication zone posed by dispersal from cotton modules during and after transport to the gin. Mark-release-recapture experiments in August and September in Texas indicated that most weevils disperse rapidly from the module surface, temperature permitting, unless confined under a module t...
