The major crops for agrochemical use are cotton, rice, maize, vegetables and top fruit for insecticides small grain cereals, rice, vines and top fruit for fungicides, and maize, soybeans, small grain cereals, rice, industrial weed control, plantations and orchards for herbicides. Other crops that may be of interest include sugar beet, oil-seed rape, potatoes and citrus dependent upon your company s presence in these crops. 

Terbumeton. Terbumeton served as a partner product to terbuthylazine for weed control in vineyards and orchards outside the United States under the trademark Caragard . Its role in these mixtures was to control deep-rooted perennial weeds. As better alternatives were developed, its use was discontinued. 

Triazine herbicides provide selective weed control in crops such as corn, sorghum, and sugarcane. In addition, some members of the triazine family are used for weed control in orchards, horticultural, and perennial crops, etc. A unique selective use of triazine herbicides is in triazine-tolerant rapeseed. Although triazine herbicides provide control of a wide variety of grass and broadleaf weeds, the long-term, widespread, and repetitive use of triazine herbicides in crop and noncrop situations has led to the selection of many triazine-resistant weeds. The physiological and biochemical basis of triazine selectivity between crops and weeds and of resistance to triazine herbicides in weeds is well understood. 

Weed Control with Hot Water Hot water to control weeds in citrus orchards and in other crops has shown potential (Anonymous, 1993a, b). The results of such treatments were comparable to contact herbicides.

Weed Control in Orchards, Vineyards, and Small Fruit... 

In the late 1950s and early 1960s cultivation equipment was the principal method of weed control (Leefe and Longley, 1960 Leonard and Lider, 1961). At the same time, there were early reports showing that selective herbicides such as simazine and diuron could provide excellent weed control in vineyards and orchards in the United States and Europe (Bourdier, 1959 Doll, 1960 Huglin, 1960 Larson and Ries, 1960 Lulliard, 1961 Leonard et al., 1964). 

A variety of preemergence herbicides are used in orchards. They may be used alone or in combination, and are often applied with a low rate of simazine. These combinations are used to increase the weed control spectrum and to decrease the chance of weed resistance. 

The principles of successful weed control in orchards include herbicide placement, movement, adsorption, absorption, translocation of herbicides, and their inherent biological activity. The residual characteristics of the herbicides are also important, as is the response of the trees and weeds. 

Many triazines have been evaluated for weed control in orchards and vineyards, but primary emphasis will be placed on simazine as the herbicide of preference in most of these crops. In general, simazine is better tolerated by most tree fruits, nuts, and vines than high rates of atrazine, prometryn, propazine, terbutryn, terbuthylazine, or metribuzin.
