“…Foliar application of pesticides as the major management practices to control pests and diseases has been widely used worldwide to increase crop production (Liu et al, 2015). Recently, there has been much interest in the incorporation of Zn into the routine spraying of foliar pesticide (Ram et al, 2016), with the rationalization that this practice will be more economical and adoptable by farmers due to the elimination of extra labor or machinery input.…”

“…Although one previous study showed that mixed foliar application of Zn and pesticides was as effective as foliar Zn alone in increasing grain Zn, only insecticides controlling aphid were tested (Wang et al, 2015b), leaving it unanswered whether foliar Zn applied together with various pesticides would affect grain Zn concentration. This issue is important because wheat is commonly attacked by other foliar diseases (e.g., head blight, powdery mildew, and leaf rust) and pests (e.g., midge and red spider mite) (Liu et al, 2015). Various kinds of insecticides and fungicides are therefore annually sprayed on wheat plants (Brauns et al, 2018).…”

Improving Zinc Concentration and Bioavailability of Wheat Grain through Combined Foliar Applications of Zinc and Pesticides

Core Ideas Foliar zinc (Zn) applied together with any pesticides caused similar increase in whole grain and grain milling fractions Zn concentrations as compared with foliar Zn application alone. Foliar Zn applied simultaneously with pesticides significantly increased estimated Zn bioavailability in whole grain and grain milling fractions; the increases were comparable to foliar Zn application alone. Higher Zn concentration and bioavailability in whole grain with Zn applied at milk stage with or without pesticides indicated efficient absorption of Zn by wheat plants compared with Zn applied at flowering stage. ABSTRACT Foliar ZnSO4 application has been shown to be effective for increasing Zn concentration in wheat (Triticum aestivum L.) grain but is time and energy consuming. For promoting adoption of this practice by growers, a field experiment was conducted in two seasons to evaluate the effects of foliar Zn combined with six commonly used pesticides (three insecticides and three fungicides) applied at flowering or milk stage on Zn concentration and bioavailability in wheat grain and its milling fractions. Grains were fractionated into flour and bran for analysis of Zn, phytic acid (PA), and other nutrients (protein, P, K, Fe, and Mn). The results showed that foliar application of Zn together with various pesticides, irrespective of pesticide type, was as effective as foliar Zn application alone in improving Zn concentrations in whole grain and in its milling fractions. Combined foliar application of Zn with pesticides did not increase PA concentration but significantly increased the estimated Zn bioavailability in flour by 79.2%, in bran by 95.4%, and in grain by 94.5%. Zinc foliar application (with or without pesticides) at milk stage resulted in a higher Zn concentration and bioavailability in whole grain than Zn applied at flowering stage. There were no adverse effects of combined foliar application of Zn and pesticides on grain yield and other nutrients. Therefore, foliar Zn application can be safely applied with commonly used fungicides or insecticides (particularly at milk stage) to enrich Zn of the whole grain and particularly the flour and represents a useful practice for overcoming human Zn deficiency.

“…Now some tell us that current agricultural practices may threaten future global food security and will have negative effects on global food production [8]. The total agricultural area has decreased since 2000, fertilizer and pesticide consumption have increased, water use efficiency has increased, and available water sources are already being used for irrigation.…”

Agriculture’s Moral Dilemmas and the Need for Agroecology

Those engaged in agriculture possess a definite but unexamined moral confidence or certainty about the correctness of what they do. The basis of the moral confidence is not obvious to those who have it, or to the public. In fact, the moral confidence that pervades agriculture is potentially harmful because it is unexamined. It is necessary that those engaged in agriculture analyze what it is about agriculture in society that favors, inhibits, or limits agriculture. All should strive to nourish and strengthen the aspects of agriculture that are beneficial and change those that are not. To do this all must be confident to study ourselves, our institutions, and be dedicated to the task of modifying the values and goals of both.

“…Industrial agricultural production methods used in Australia may not guarantee food security [92,93]. The sustainability of modern agricultural production is in question in Australia and internationally especially as intensification is likely to lead to a tradeoff between production and more environmental damage [94]. The level of relative poverty in Australia [46], especially among children, contrasts with traditional Australian values of mateship and empathy [95,96].…”

Finding Ways to Improve Australia’s Food Security Situation

Although Australia exports more than half of its agricultural production, there are food security problems as the current food supply systems in Australia fail to deliver healthy diets to all Australians and fail to protect the natural resources on which they depend. In addition, the food systems create "collateral damage" to the natural environment including biodiversity loss. In coming decades, Australia's food supply systems will be increasingly challenged by resource price inflation and falling yields due to climate change. Government and business are aiming to increase production and agricultural exports. This will increase pressure on agricultural resources and exacerbate "collateral" damage to the environment. The Australian public has an ongoing interest in issues associated with the food systems including the environment, education, health and sustainability. A health-giving diet is essential for a full life and over a life-time people need food security. Currently economy development and social planning is undertaken through the pragmatic application of a set of ideas, such as relying on markets and deregulation, collectively referred to as neoliberalism. This paper contends that the neoliberal approach is not solving the current and developing problems in food security and agriculture more generally and suggests that more emphasis should be given to alternatives approaches. Seven alternatives approaches are suggested that could be used to identify gaps and guide the creation of overarching goals in economic development and social planning to improve food security and secure the other material goods and social arrangements that all Australians require to live full lives. However, changing large systems such as those involved in food supply is difficult because vested interests in the existing arrangements make the current systems resilient to change. There are a range of leverage points that have differing abilities to change systems. The paper points out that goals and information flows are good leverage points and suggests establishing overarching goals for the systems relevant to food and restructuring the flow of information about these systems will help reform the food supply systems in Australia.
