Los escarabajos del pepino están presentes a través de los Estados Unidos y causan un serio daño a los cultivos de cucurbitáceas — pepinos, melones, zapallos, y calabazas.
Insects and mites can cause severe problems in the production of watermelon, squash, cucumber, and cantaloupe either through direct damage to the crop or through transmission of disease agents, such as the aphid-borne mosaic viruses. Common pests of cucurbits are described below. The importance of a particular insect will vary by region and by crop. For example root maggots are more important in North Florida and melon thrips in South Florida.

Powdery Mildew (Sphaerotheca fuliginea Schlechtend.:Fr, Pollaci) Control with Vegetable Oils and Mineral Salts on Cucumber Growing in Greenhouse in Sinaloa, México
The effect of biocompatible products on the growth of cucumber powdery mildew (Sphaerotheca fuliginea) was evaluated. Plants were treated with dispersions or solutions of sunflower, olive and neem oils and potassium bicarbonate, potassium silicate and monopotassium phosphate, and compared with azoxystrobim.
Control de Cenicilla (Sphaerotheca fuliginea Schlechtend.:Fr, Pollaci) con Aceites Vegetales y Sales Minerales en Pepino de Invernadero en Sinaloa, México.
The entire range of crops referred to as cucurbits are affected by various foliar diseases in the Northeast. Most damage appears on leaves and stems, but in several instances the fruit are directly infected or will develop poorly if foliar infections are severe. The diseases discussed are angular leaf spot, caused by the bacterium Pseudomonas syringae pv.
The major emphasis of a plant disease control program for greenhouse vegetable production is on prevention. It is far more expedient to prevent the introduction of a plant pathogen than it is to control it once it is present. The major reason for this is that few fungicides have been or are likely to be labeled for use on vegetables in the greenhouse.
Fresh-market vegetable supplies have been sporadic following several December freezes in Florida, periods of cool, wet weather in coastal California, and several periods of subfreezing temperatures in California and Arizona. In addition, Mexican vegetables were damaged by a 2-day freeze in early February (extent of damage is unknown at this time). As a result, vegetable prices are now at or above the highs experienced a year earlier.
Market, Certification and Production Information for Producers and International Trading Companies
For some people organic agriculture is “farming without chemical fertilizers and pesticides”. This is short and concise, but misses important characteristics. Organic agriculture follows the logic of a living organism in which all elements (soil, plants, farm animals, insects, the farmer etc.) are closely linked with one other. Organic farming therefore must be based on a thorough understanding and clever management of these interactions and processes.
