The term “pesticide” indicates a wide range of compounds such as insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides and plant growth regulators. In Tunisia, weeds and phytopathogenic fungi can cause high yield loss, attaining 80%. Fungi as plant pathogens cause a variety of plant diseases resulting in losses both in food crop production and after harvest. […]

This occurs when a viable virus is formed with DNA components from different bipartite viruses
The monopartite genomic DNA is similar in sequence and genome organization to the DNA-A component of bipartite begomoviruses, with one gene on the v-sense strand encoding the CP, and four genes on the c-sense strand encoding Rep, TrAP, Ren and the C4/AC4 protein. The DNA-B component of the bipartite begomoviruses has two genes, BV1 and BC1, which […]
These programs tend to focus on things that growers do not always value
While water holding capacity and infiltration can be improved with management, soil type is inherent to a location, which is why research should be localized. Increasing soil organic matter will have a greater impact on available water holding capacity in sandy soils than in silty clay loam and silt loam soils . Another focus could be […]
The standard fumigatedbeds had generally low nitrate nitrogen
However, the substrate treatments did not affect the marketable fruit yield. Significant differences were noted only on the cull yield. The highest cull yield was observed in the steamed soil with amendments; this was the case at both Mar Vista Berry and Monterey Bay Academy, and it could be attributed to the very low pH […]
Glyphosate is an effective herbicide that is available to landowners for control of broom
Deer, rabbits, and other herbivores do not readily graze brooms, possibly due to the bitter taste of the stems and the availability of more palatable forage . However, grazing does occur in other parts of the world, where goats control Scotch broom.Using fire to control Scotch and French brooms has had varied results. Some researchers […]
Trees are used to construct poles for hanging tobacco and barns for air drying tobacco
The person may be unable to repay the loan when the loan interest is too high or inflated. In some cases, the person’s work is sufficient to cover the interest but not the principle. Individuals become trapped by debt when it is passed on to future generations. The International Labor Organization Convention 182 describes bonded […]
Much of that reservoir water also goes toward municipal potable water and irrigation for other crops in the area
The water-seeded production system in California is a common method to suppress weedy grasses and non-aquatic weed species. In California, pregerminated rice seed is air-seeded onto fields with a 10- to 15-cm standing flood and the fields are typically maintained continuously flooded throughout the growing season . The California rice cropping system is again unique […]
The levels observed are not concerning in terms of environmental contamination
Additionally, downstream water quality affected by use of herbicidesin water-seeded rice is of paramount concern because of the proximity to other high value crops which may use the water for irrigation and proximity to urban settlements which may use the water for consumption . The US Environmental Protection Agency recorded pendimethalin risk of contaminating surface […]
Farmers may also grow cover crops during the off-season
Similar to the no or little effect of cover crop treatments on insect pest population densities, my research findings cannot confirm that off-season cover cropping reduces crop damage in the subsequent vegetable crop. In contrast, many researchers observed that crop damages can be minimized in a mixed cover and main crop interplanting. These researchers argue […]
Selective suppression of weed species with glucosinolate compounds was documented
Lower population densities of common purslane and all weeds combined were observed at harvest time for cover crop treatments in 2009 compared to summer fallow . Among the cover crops, vegetable crops that had cowpea as a summer cover crop had fewer population of weeds than the marigold . Compared to the previous years, the […]
