Downy Mildew of Cucumber Detected in South Georgia

By Bhabesh Dutta, Downy mildew of cucumber has been detected from the Brooks County, GA. These observations indicate that inoculum of downy mildew is currently in southern GA counties  and under favorable conditions  potential disease outbreak in other cucurbits  can occur. I would suggest our cucurbit growers to look for the downy mildew symptoms in their fields and start applying protective spray of below stated fungicides.

 

 

 

Watermelon: Rotation (foliar application)  with  Orondis ultra (provide protection against both Downy and P. capsici);

Elumin+Bravo/Manzate;

Ranman+Bravo/Manzate;

Previcur flex+Bravo/Manzate

 

Please do not use Bravo after fruit set.

 

Other cucurbits: Orondis opti;

Elumin+Bravo;

Ranman+Bravo

Previcur flex+Bravo

 

If Orondis was used as a soil application, please do not use it as foliar (use restriction according to label).

The Impacts of China Trade Tariffs on Georgia Livestock Industry

By Levi Russell

China implemented a 25 percent increase in import tariffs on United States pork and is expected to increase import tariffs on United States beef products by 25 percent. However, unlike many row crops and other agricultural products, China is not a primary destination for United States meat products. Beef exports to China only resumed recently and there is not yet a significant amount of beef being produced in the United States that is exported to China. In 2017, the United States was the second largest pork producer after China, and the largest pork exporting country (USDA FAS, 2018b). Twenty-two percent of pork produced in the United States enters the export market (USDA FAS, 2018b). From January 2013 to January 2018, the USDA ERS reports that mainland China made up 7.5% of total United States pork exports, coming behind Mexico (29.3%), Japan (25.1%), Canada (10.4%), and South Korea (8.1%). Pork production is mainly concentrated in the Midwest and North Carolina, and Georgia is not in the major pork producing regions. The impact of the tariffs on pork will be minimal on Georgia’s agricultural industry. However, the reductions in pork prices could hurt some of the pork producers in Georgia. For beef and pork (and other meats), the NAFTA trade discussions are a far bigger concern than Chinese tariffs.

Short-term market fluctuations this year in both cattle and hog markets will almost certainly depend much more on rising supplies, domestic consumption, and exports to other countries than on Chinese tariffs. A recent report by the USDA FAS indicates that the reductions in exports to China will mostly be offset by the increases in shipments to Japan, Mexico, and the Philippines. Exports of both pork and beef from the United States are expected to rise this year, in part due to relatively low United States prices (USDA FAS, 2018a).

In the long term, however, these increased tariffs on pork and beef products constitute a missed opportunity, as China is the number one pork-consuming nation in the world. New sources of demand for United States producers are hard to come by and higher tariffs on beef and pork will likely result in increased production in other countries to fulfill China’s growing demand. This will put the United States at a competitive disadvantage in the long term if the tariff increases are put in place on United States beef and pork products.

Some relevant information on Powdery mildew of cucurbits

Powdery mildew is a common disease of cucurbits under field and greenhouse conditions in most areas of the United States.  Although all cucurbits are susceptible, symptoms are less common on cucumber and melon because many commercial cultivars have resistance. This disease can be a major production problem if not manage timely.

Podosphaera xanthii and Erysiphe cichoracearum are the two important fungal organisms that cause cucurbit powdery mildew. P. xanthii is a more aggressive pathogen than E. cichoracearum.  E. cichoracearum requires a lower temperature optimum and hence, this fungus is found mainly during cooler spring and early summer periods. In contrast, P. xanthii are more common during the warmer months.

The causal fungi are obligate parasites and therefore cannot survive in the absence of living host plants. Possible local sources of initial inoculum include conidia from greenhouse-grown cucurbits, and alternate hosts. Verbena, a common ornamental plant and also a common weed, could be an important source of inoculum.

Pathogenically distinct races of Podosphaera xanthii have been differentiated on muskmelon.  Races 1 and 2 have most common in the eastern United States recently.

Fungicides: Quintec, Proline, Torino (rotation in watermelon and cantaloupe)

Proline, Torino, Procure (rotation in other cucurbits)

Pecan herbicide injury

Dr. Lenny Wells shares shares information on herbicide damage in pecan trees.  Row crop planting has started in south Georgia and this means herbicide drift season has arrived. I have been on the road all week looking at drift-damaged trees. Since I cannot make it to every orchard in which this occurs, here are the steps that should be taken when a drift incident happens:

Glyphosate injury on both leaves to the left. ZInc deficiency on leaf to the right.

Glyphosate injury to pecan

If growers have had herbicide drift injury occur on their trees, they should first contact their county agent and take photos for documentation. The Georgia Department of Agriculture should also be contacted to take their own samples as soon as possible if a complaint will be filed. Many of these herbicides have a very short half-life and samples must be taken quickly in order to detect them in leaf tissue.  The next step is to contact the neighbor from whom the drift originated and contact the neighbor’s insurance agency to notify them the incident occurred. Once everything has been documented it is usually a wait and see situation because of the high degree of variability from one case to the next. Often with glyphosate, glufosinate, paraquat, and flumioxazen, the injury is more cosmetic than economic unless there is extensive coverage, leading to significant leaf and flower/nut loss. Quality may also be affected if extensive foliage damage occurs because the trees must expend energy to re-grow new foliage. The only way to know the extent of damage for sure is to evaluate the crop at the end of the season. Repeated injury, of course, will lead to more serious losses and can cause long term damage to the trees.

Paraquat injury to pecan. Damage initially appears as yellowing of tissue and then turns brown and necrotic.

Older paraquat injury to pecan. All damaged tissue has turned brown and necrotic.

Dicamba and 2,4-d may throw a more complicated scenario into the equation. Based on data from the trials Dr. Eric Prostko and I have been conducting, injury from these materials, especially 2,4-D can be more serious if a high rate of the chemical makes direct contact with the tree’s tissue. In this case we have seen death of those branches that had direct contact. Once again, the degree of damage severity will depend on the rate and coverage. The same steps described above should be taken in the event of drift from these materials.

The Impacts of China Trade Tariff on Georgia Row Crops

By Yangxuan LiuAdam N. Rabinowitz, and Don Shurley

China announced plans to implement a 25 percent increase in import tariffs on major agricultural commodities from the United States, which includes soybeans, corn and corn products, wheat, sorghum, cotton, and tobacco and tobacco products. The overall United States export value for these agricultural commodities to China are worth around 44.7 billion dollars (USDA FAS, 2018a).

United States agriculture relies on the export markets to absorb its excess supply in order to support domestic agricultural prices. The United States is the largest exporting country for corn, cotton, and sorghum, and the second largest exporting country for soybean and wheat (USDA FAS, 2018b). China is the largest trading partner for United States sorghum and soybean, and the second largest trading partner for cotton (USDA FAS, 2018a). In 2017, China bought 81.4% of the United States sorghum exports, 57.3% of the United States soybean exports, 16.7% of the United States cotton exports, 5.7% of the United States wheat export, and 1.6% of the United States corn export (Table 1).

The Chinese tariffs, if implemented, will increase the United States agricultural prices faced by the Chinese consumers relative to other countries. Thus, it will reduce demand for United States agricultural commodities by Chinese consumers. As a result, the United States needs to find alternative foreign markets to export its excess supply in order to sustain current prices. China is the largest importing country for sorghum and soybean (USDA FAS, 2018b). Developing alternative markets for these commodities might be difficult. Although much of the soybeans going to the European Union typically come from Brazil, the European Union (import 14.8% of soybean traded globally) can serve as an alternative market for United States soybeans. Globally, it is a very competitive supply market for soybeans. China could diversify its suppliers in the long run and purchase more soybeans from Brazil (export 39.8% of soybean traded globally) and Argentina (export 17.0% of soybean traded globally) (USDA FAS, 2018b). In the short run, there will not be enough capacity for these countries to increase their production acres. China will still need to buy American soybeans and sorghum to satisfy their domestic consumption.

China is the third largest importing country for cotton, importing 13.1% of cotton traded globally in 2017 (USDA FAS, 2018b). If the Chinese tariffs on U.S. cotton are put into effect, it might provide a near term opportunity for global cotton suppliers like India, Australia, and Brazil to supply more cotton to China. However, the longer term situation could involve more of a re-routing of U.S. exports to other cotton importing countries, like Vietnam, Bangladesh, Indonesia, Pakistan, and India, than a reduction in U.S. cotton production. Recent history of the change in China’s internal cotton policy has shown that the disruptions of Chinese raw cotton imports stimulates the importing of duty free yarn from countries like Vietnam, Indonesia, and the Indian subcontinent (J.R.C. Robinson, personal communication, April 2018; Shurley, 2018).

A study conducted at Purdue University found that the prices of United States soybeans would fall by 2 and 5% under the 10 and 30 percent tariff, respectively (Pack, 2018). Similar effects of price reduction are expected to the other agricultural commodities. The tariff impact on the sorghum price is expected to be larger than the impact on the soybean price, while the impact on the cotton price is expected to be smaller than the impact on the soybean price.

The potential 25 percent increment in tariff for corn, cotton, sorghum, soybeans, and wheat could have a negative impact to Georgia’s agricultural industry. Cotton is the largest crop produced in Georgia with more than 1.27 million acres harvested last year, and contributes $794 million to Georgia’s economy (Table 2). Georgia produced 10.6% (2.25 million bales) of the total United States cotton production in 2017, and is the second largest cotton producing state after Texas. It is also the second largest cotton export state after Texas. Last year, Georgia exported $441 million of cotton, of which $26 million of cotton was exported to China (USDA FAS, 2018a). The Chinese tariffs will have a direct impact on the cotton exported from Georgia because tariffs will impact the entire United States cotton market and the prices received by every United States cotton farmer. It will also have an indirect impact through the prices received by Georgia cotton farmers. Even though Georgia does not export corn, sorghum, soybean, and wheat directly to China, the lower price of these commodities due to Chinese tariffs would impact Georgia farmers.

Thrips Monitoring 2018

UGA  peanut  entomologist  Dr. Mark Abney shares some information on thrip  monitoring,  he has seen across the state and offers recommendations for treating. Peanuts are being planted, and tobacco thrips are moving in Georgia. Trap captures increased significantly at four of our six monitoring locations last week. This means that peanuts emerging over the next couple of weeks will be at relatively high risk for infestation. Using an at-plant insecticide with proven efficacy will usually be sufficient to keep thrips injury low, but growers are still strongly encouraged to scout fields for thrips activity. Growers who are not using an at-plant insecticide should be prepared to make foliar applications (usually acephate) for thrips if they want to avoid injury. Remember that phorate (Thimet) in-furrow is the only insecticide that has been proven to reduce the risk of tomato spotted wilt disease in peanut.  We are in the first two weeks of thrips dispersal, and we do not know how long flights will continue or how large populations will be. We will continue to post weekly updates of trapping data as the planting season progresses.

These data are being provided for informational purposes only and may not be representative of thrips dispersal at your location. Peanut fields should be scouted regularly to quantify actual thrips populations.

If you have questions about thrips or thrips management please contact your local county Extension agent.
