Texas Agriculture Commissioner Sid Miller is urging Texans to take extreme precaution when receiving unsolicited seed packets from China. These packets have been mailed to multiple states, including Texas, falsely labeled as jewelry. Residents are advised not to plant the seeds as they could contain harmful invasive species or be otherwise unsafe.


"I am urging folks to take this matter seriously," Commissioner Miller said. "An invasive plant species might not sound threatening, but these small invaders could destroy Texas agriculture. TDA has been working closely with USDA to analyze these unknown seeds so we can protect Texas residents."


If you receive a foreign package containing seeds do not open it or plant the contents. Keep contents contained in their original sealed package.


An invasive species is an organism that is not native to a particular region. The introduction of this "alien species" can cause economic or environmental harm. In agriculture, an invasive species can destroy native crops, introduce disease to native plants and may be dangerous for livestock.

Hot hay can ruin your day


Barn fires never happen, until they happen. While racing the rain and harvesting that last cutting may be cause for celebration, hold the applause for a few weeks. Hay that is cut and baled with high moisture is at risk for spontaneous combustion for up to three weeks as the plant cells are still respiring.


When baled at moistures over 20 percent, mesophilic (warm temperature) bacteria release heat, causing temperatures to reach between 130°F and 140°F. If bacteria die and bales cool, you are in the clear, but if thermophilic bacteria take over, temperatures can rise to over 175°F.


Although temperatures of 110°F are common the first five days after baling, it is recommended using a hay temperature probe to monitor the internal temperature for the three-week window post-baling. Bales at risk should not be stacked and should be kept outside or in an area with adequate ventilation to assist in drying.


Higher risk hay as having moisture levels above 20 percent and without the use of a hay preservative. Also, be cautious of hay coming from fields with wet spots or uneven drying. Most fires occur within the first six weeks after baling.


Monitoring at-risk hay


Check at-risk hay twice a day until low temperatures stabilize. Monitor internal temperatures at the center of the stack, or around 8 feet down in larger stacks.


A probe thermometer can be made by using a 3/4-inch pipe with the ends closed into a point and 3/16-inch holes drilled into the bottom 4 inches. A thermometer can then be lowered into the pipe on a string and left inside the stack for 15 minutes for an accurate reading.


Another method to determine fire risk is by sticking a 3/8-inch pipe into the stack twice a day. If it is too hot to hold, hay is at risk for fire.


Take proper safety precautions when checking hay. Using planks to disperse weight can help prevent falling into burned-out cavities. If a harness is not readily available, make sure there are people nearby to help monitor the situation.


Hay bale temperatures of 120°F to 130°F will likely result in mold growth and will make the protein in the hay less available to animals.


While these temperatures will not cause fires, continued mold growth can raise temperatures to dangerous levels. At 160°F to 170°F, there is cause for alarm and the fire department should be alerted immediately.


At those elevated temperatures, other chemical reactions begin to occur that elevate the temperature much higher, resulting in spontaneous combustion of the hay in a relatively short period of time.


When the haystack temperatures exceed 170°F, safely evacuate any livestock or machinery that are located in the same barn. Call the fire department before trying to move hay.


Temperature (°F)Condition and action


125°No action needed.


150°Hay is entering the danger zone. Check twice daily. Disassemble stacked hay bales to promote air circulation to cool the hay outside.


160°Hay has reached the danger zone. Check hay temperature every couple of hours. Disassemble stacked hay to promote air circulation to cool hay, and have fire department present while unstacking from here on.


175°Hot pockets are likely. Alert fire service to possible hay fire incident. Close barns tightly to eliminate oxygen.


190°With the assistance of the fire service, remove hot hay. Be aware the bales may burst into flames. Keep tractors wet.


200°+With the assistance of the fire service, remove hot hay. Most likely, a fire will occur. Keep tractors wet and fire hose lines charged in the barn and along the route of where bales are to be stacked.
