Parasitoid helps control fruit worm in Sacramento Valley processing tomatoes Texte intégral
1990
M Hoffmann | L Wilson | F Zalom | R Hilton | C Weakley
Naturally occurring populations of the parasitic wasp Trichogramma help control the tomato fruit worm in processing tomatoes grown in the Sacramento Valley. Incorporating this factor into the pest management decision-making process should reduce insecticide applications needed to control the pest.

Por la gran importancia que en el comportamiento adulto de los frutales, tienen las malas hierbas que compiten con ellos en el vivero o en las plantaciones jovenes, se indican a continuacion algunos herbicidas autorizados en frutales de mas de cuatro anos que pueden ser utilizados en viveros con las debidas precauciones. Los autores se basan en sus experiencias en la Comunidad Autonoma de Aragon, una de las principales regiones espanolas productoras de plantones y portainjertos

Effect of paclobutrazol on growth, flowering, fruit setting, fruit quality and yield of apple cv. Anna and Ein Shemer
1990
Phichit Sripinta
Paclobutrazol treated plants produced shorter new shoot/10 square cm trunk cross section area than that in the control plants. Paclobutrazol applied as soil drenching and as foliage spray in the late vegetative stage in the Anna and Ein Shemer cultivars produced early flowering than those of the control trees. Whereas the foliage sprayed at 2 weeds after petal fall in the Ein Shemer cultivar and the soil drenching method at the late vegetative stage in the Anna cultivar caused late flowering. The paclobutrazol applied trees had higher number of spurs, more flowers per tree, higher percent fruit set, greater fruit weight per 10 square cm trunk cross section area, higher fruit firmness at harvest and later harvesting time than those of the control trees. The soil drench and foliage spray methods of the Ein Shemer at the late vegetative stage and foliage spray method in the Anna at the 2 weeks after petal fall produced lesser characters in fruit width, fruit length and fruit weight than those of the control trees. But the foliage sprayed Anna trees at the late vegetative period as well as in the Ein Shemer trees at 2 weeks after petal fall caused an increase in fruit width, fruit length and average fruit weight. The higher concentration of paclobutrazol the more fruit colour development was found.
