Đã điều tra lectin của 6 giống đậu cô ve thấy rằng cả 6 giống đều có hoạt tính lectin trong đó giống đậu cove hạt trắng dạng bụi (white bean core bush type white seeds) có hoạt tính lectin mạnh nhất, đặc biệt đối với hồng cầu trâu, bò, lợn. Lectin của 6 giống này đều không có biểu hiện đặc hiệu nhóm máu. Lectin đậu cove hạt trắng dạng bụi hoạt động tốt nhất ở nhiệt độ 300C – 400C, pH 6,8 – 7,6. Các đường α-D-glucose, α-D-galactose, D-mannose, D-fructose, D-saccharide,  D-lactose, D-arabinose và D-manitose ở nồng độ 0,05 – 0,1 M có tác dụng kìm hãm hoạt tính của lectin đậu cove hạt trắng dạng bụi. Lectin này cũng bị kìm hãm bởi protein của một số huyết thanh người và động vật (trâu, bò, lợn). Đã tinh sạch lectin đậu cove hạt trắng dạng bụi có độ tinh sạch gấp khoảng 52 lần so với dịch thô ban đầu. Trên gel polyacrylamide thấy xuất hiện 5 band có khối lượng phân tử trong khoảng 30 – 97 kDa.

Relationships between the distribution and numbers of apothecia of Sclerotinia sclerotiorum (Lib.) de Bary and the distribution and incidence of white mold of white bean (Phaseolus vulgaris L.) were investigated in a field plot at Arkell, Ont., in 1981 and 1982. The spatial distributions of both apothecia and disease were aggregated and were most consistently described by the negative binomial distribution, although the Poisson, Poisson binomial and logarithmic with zeros distributions were also significant for some sampling dates. Numbers of apothecia were correlated with disease incidence within areas 1.4 (r = 0.07–0.67), 36 (r = 0.11–0.72), and 108 m2 (r = 0.21–0.95). The quantitative relationships between apothecia within a field of beans and the incidence of white mold may be useful in predicting the disease.

Six field experiments were conducted over a two-year period (2013 and 2014) to evaluate the tolerance of white bean and spectrum of weeds controlled with halosulfuron applied preplant incorporated (PPI) alone or tankmixed with trifluralin, pendimethalin, EPTC, dimethenamid-P, or S-metolachlor. Halosulfuron applied alone or in tankmix with trifluralin, pendimethalin, EPTC, dimethenamid-P, or S-metolachlor caused 2% or less visible injury 1 and 4 weeks after emergence (WAE). Halosulfuron applied PPI controlled common lamb's-quarters, wild mustard, redroot pigweed, and common ragweed greater than 90% and green foxtail less than 60% 4 and 8 WAE. Weed biomass and density followed a similar pattern. White bean yield with halosulfuron applied alone or in tankmix with the same herbicides was equivalent to the weed-free control.

Plot Design

The combined effect of N fertilization and Rhizobium inoculation on bean (Phaseolus vulgaris L., cv. Bonita) nodulation and yield was studied in the semi-arid southern region of Puerto Rico. Six N treatments: 0, 22, 45, 90, 180 and 360 kg/ha were tested in inoculated and noninoculated plots arranged in a split-plot design with 4 replications. The application of 22 kg/ha of N in the inoculated plots increased plant nodulation 4 and 8 weeks after planting. Higher rates of N fertilization reduced the number and size of bean nodules at both sampling dates. On the other hand, dry beans consistently increased with applications of 0 to 180 kg/ha of N in the presence of Rhizobium.
